AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER PREFACE Introduction The International Plumbing Code (IPC ) establishes minimum requirements for plumbing systems using prescriptive and performance -related provisions. It is founded on broad -based principles that make possible the use of new materials and new plumbing designs. This 2018 edition is fully compatible with all of the International Codes (I -Codes) published by the International Code Council (ICC ), including the International Building Code , International Energy Conservation Code , International Existing Building Code , International Fire Code , International Fuel Gas Code International Green Construction Code International Mechanical Code International Private Sewage Disposal Code International Property Maintenance Code , International Residential Code , International Swimming Pool and Spa Code , International Wildland-Urban Interface Code , International Zoning Code and International Code Council Performance Code The I -Codes, including this International Plumbing Code, are used in a variety of ways in both the public and private sectors. Most industry professionals are familiar with the I -Codes as the basis of laws and regulations in communities across the U.S. and in other countries. However, the impact of the codes extends well beyond the regulatory arena, as they are used in a variety of nonregulatory settings, including: Voluntary compliance programs such as those promoting sustainability, energy efficiency and disaster resistance. The insurance industry, to estimate and manage risk, and as a tool in underwriting and rate decisions. Certification and credentialing of individuals involved in the fields of building design, construction and safety. Certification of building and construction -related products. U.S. federal agencies, to guide construction in an array of government -owned properties. Facilities management. Best practices" benchmarks for designers and builders, including those who are engaged in projects in jurisdictions that do not have a formal regulatory system or a governmental enforcement mechanism. College, university and professional school textbooks and curricula. Reference works related to building design and construction. 2018 INTERNATIONAL PLUMBING CODE M CopyngbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,dv od om).(Qty of PnmdNmod)Odo,Nomb,,x1ooe1voM 01 JM 15. x m.o oc ae AM (PET) Mt,b,mt to LET Ag,, ^®'^Rt, ICC No fwN¢[TAodomo,,m AtO, Tgoodomo- by anytlt Party oT ATmboemd,Oo d Mglo—ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER REICLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT. AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER In addition to the codes themselves, the code development process brings together building professionals on a regular basis. It provides an international forum for discussion and deliberation about building design, construction methods, safety, performance requirements, technological advances and innovative products. Development This 2018 edition presents the code as originally issued, with changes reflected in the 2003 through 2015 editions and with further changes approved by the ICC Code Development Process through 2017. A new edition such as this is promulgated every 3 years. This code is founded on principles intended to establish provisions consistent with the scope of a plumbing code that adequately protects public health, safety and welfare; provisions that do not unnecessarily increase construction costs; provisions that do not restrict the use of new materials, products or methods of construction; and provisions that do not give preferential treatment to particular types or classes of materials, products or methods of construction. Maintenance The International Plumbing Code is kept up to date through the review of proposed changes submitted by code enforcement officials, industry representatives, design professionals and other interested parties. Proposed changes are carefully considered through an open code development process in which all interested and affected parties may participate. The ICC Code Development Process reflects principles of openness, transparency, balance, due process and consensus, the principles embodied in OMB Circular A-119, which governs the federal government's use of private -sector standards. The ICC process is open to anyone; there is no cost to participate, and people can participate without travel cost through the ICC's cloud - based app, cdp-Access . A broad cross section of interests are represented in the ICC Code Development Process. The codes, which are updated regularly, include safeguards that allow for emergency action when required for health and safety reasons. In order to ensure that organizations with a direct and material interest in the codes have a voice in the process, the ICC has developed partnerships with key industry segments that support the ICC's important public safety mission. Some code development committee members were nominated by the following industry partners and approved by the ICC Board: American Institute of Architects (AIA) American Society of Plumbing Engineers (ASPE) National Association of Home Builders (NAHB) Plumbing Heating and Cooling Contractors (PHCC) 2018 INTERNATIONAL PLUMBING CODE (ATFIgbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,dv od om).(Qty of PnmdNmod)Odo,Nomb,,x1ooe1voM 01 JM 15. xm.o oc ae AM (PET) Mt,b,mt to LET Ag,, ^®'^Rt, ICC No fwN¢[TAodomo,,m AtO, Tgoodomo- by anytlt Party oT ATmboemd,Oo d Mglo—ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER REICLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT. AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER The Code Development Committees evaluate and make recommendations regarding proposed changes to the codes. Their recommendations are then subject to public comment and council -wide votes. The ICC's governmental members —public safety officials who have no financial or business interest in the outcome —cast the final votes on proposed changes. The contents of this work are subject to change through the code development cycles and by any governmental entity that enacts the code into law. For more information regarding the code development process, contact the Codes and Standards Development Department of the International Code Council. While the I -Code development procedure is thorough and comprehensive, the ICC, its members and those participating in the development of the codes disclaim any liability resulting from the publication or use of the I -Codes, or from compliance or noncompliance with their provisions. The ICC does not have the power or authority to police or enforce compliance with the contents of this code. Code Development Committee Responsibilities (Letter Designations in Front of Section Numbers) In each code development cycle, proposed changes to the code are considered at the Committee Action Hearings by the International Plumbing Code Development Committee, whose action constitutes a recommendation to the voting membership for final action on the proposed change. Proposed changes to a code section that has a number beginning with a letter in brackets are considered by a different code development committee. For example, proposed changes to code sections that have [BS] in front of them (e.g., [BS] 309.2) are considered by the IBC —Structural Code Development Committee at the code development hearings. The bracketed letter designations for committees responsible for portions of this code are as follows: [A] = Administrative Code Development Committee; [BE] = IBC —Egress Code Development Committee; [BG] = IBC —General Code Development Committee; [BS] = IBC —Structural Code Development Committee; [E] = International Energy Conservation Code Development Committee; [F] = International Fire Code Development Committee; and [M] = International Mechanical Code Development Committee. For the development of the 2021 edition of the I -Codes, there will be two groups of code development committees and they will meet in separate years. Note that these are tentative groupings. 2018 INTERNATIONAL PLUMBING CODE 6 CopyngbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,dv od om).(Qty of PnmdNmod)Odo,Nomb,,x1ooe1voM 01 JM 15. xm.o oc ae AM (PET) Mt,b,mt to LET Ag,, ^®'^Rt, ICC No fwN¢[TAodomoo.m AtO, Tgoodomo- by anytlt Party oT ATmboemd,Oo d Mglo—ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER REICLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT.

Because different committees hold Committee Action Hearings in different years, proposals for the IPC will be heard by committees in both the 2018 (Group A) and the 2019 (Group B) code development cycles. For instance, every section of Chapter 1 of this code is designated as the responsibility of the Administrative Code Development Committee, which is part of the Group B portion of the hearings. This committee will hold its Committee Action Hearings in 2019 to consider code change proposals for Chapter 1 of all I -Codes except the International Energy Conservation Code, International Residential Code and International Green Construction Code. Therefore, any proposals received for Chapter 1 of this code will be assigned to the Administrative Code Development Committee for consideration in 2019. 2018 INTERNATIONAL PLUMBING CODE 7 CopyngbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(R dme pooch od om).(Dby of PnmdNmod)Odo,Nomb,,x1ooe1voM 01 JM 15. x m.o oc ae AM (PET) Mt,b,mt to Lie Ag,, ^®'^Rt, ICC No fwN¢[Todomoo.m AtO, goodomo- by anytlt Party o, Axmboemd,Oo d Mglo—ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER REICLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT.

Marginal Markings Solid vertical lines in the margins within the body of the code indicate a technical change from the requirements of the 2015 edition. Deletion indicators in the form of an arrow (—) are provided in the margin where an entire section, paragraph, exception or table has been deleted or an item in a list of items or a table has been deleted. A single asterisk ['] placed in the margin indicates that text or a table has been relocated within the code. A double asterisk ["] placed in the margin indicates that the text or table immediately following it has been relocated there from elsewhere in the code. The following table indicates such relocations in the 2018 edition of the International Plumbing Code. 2018 LOCATION 2015 LOCATION 802.2 804.1 Coordination of the International Codes The coordination of technical provisions is one of the strengths of the ICC family of model codes. The codes can be used as a complete set of complementary documents, which will provide users with full integration and coordination of technical provisions. Individual codes can also be used in subsets or as stand-alone documents. To make sure that each individual code is as complete as possible, some technical provisions that are relevant to more than one subject area are duplicated in some of the model codes. This allows users maximum flexibility in their application of the I -Codes. Italicized Terms Words and terms defined in Chapter 2, Definitions, are italicized where they appear in code text and the Chapter 2 definition applies. Where such words and terms are not italicized, common - use definitions apply. The words and terms selected have code -specific definitions that the user should read carefully to facilitate better understanding of the code. Adoption The International Code Council maintains a copyright in all of its codes and standards. Maintaining copyright allows the ICC to fund its mission through sales of books, in both print and electronic formats. The ICC welcomes adoption of its codes by jurisdictions that recognize and acknowledge the ICC's copyright in the code, and further acknowledge the substantial shared value of the public/private partnership for code development between jurisdictions and the ICC. 2018 INTERNATIONAL PLUMBING CODE (ATFIgbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rvdme Oo,dT od om).(Qty of PnmdNmod)Odo,N=b,,x1ooe1voM 01 JM 15. xm.o oc ae AM (PET) Mt,b,mt to LET Ag,, ^®'^Rt, ICC No fwN¢[TAodomo,,m AtO, Tgoodomo- by anytlt Party oT ATmboemd,Oo[vsd Mglo—ody oTyncg and Nyodwg TMARISd ANY VNAVTHO RIVER REICLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT.

AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER EFFECTIVE USE OF THE INTERNATIONAL PLUMBING CODE The International Plumbing Code (IPC) is a model code that regulates the design and installation of plumbing systems including the plumbing fixtures in all types of buildings except for detached one -and two-family dwellings and townhouses that are not more than three stories above grade in height. The regulations for plumbing systems in one- and two-family dwellings and townhouses are covered by Chapters 25 through 33 of the International Residential Code (IRC). The IPC addresses general plumbing regulations, fixture requirements, water heater installations and systems for water distribution, sanitary drainage, special wastes, venting, storm drainage and medical gases. The IPC does not address fuel gas piping systems as those systems are covered by the International Fuel Gas Code (IFGC). The IPC also does not regulate swimming pool piping systems, process piping systems, or utility -owned piping and systems. The purpose of the IPC is to the establish the minimum acceptable level of safety to protect life and property from the potential dangers associated with supplying potable water to plumbing fixtures and outlets and the conveyance of bacteria -laden waste water from fixtures. The IPC is primarily a specification -oriented (prescriptive) code with some performance - oriented text. For example, Section 405.1 is a performance statement but Chapter 6 contains the prescriptive requirements that will cause Section 405.1 to be satisfied. Where a building contains plumbing fixtures, those fixtures requiring water must be provided with an adequate supply of water for proper operation. The number of required plumbing fixtures for a building is specified by this code and is based upon the anticipated maximum number of occupants for the building and the type of building occupancy. This code provides prescriptive criteria for sizing piping systems connected to those fixtures. Through the use of code -approved materials and the installation requirements specified in this code, plumbing systems will perform their intended function over the life of the building. In summary, the IPC sets forth the minimum requirements for providing safe water to a building as well as a safe manner in which liquid - borne wastes are carried away from a building. 2018 INTERNATIONAL PLUMBING CODE 10 CopyngbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,dv od om).(Qty of PnmdNmod)Odo,Nomb,,x1ooe1voM 01 JM 15. xm.o oc ae AM (PET) Mt,b,mt to LET Ag,, ^®'^Rt, ICC No fwN¢[TAodomoo.m AtO, Tgoodomo- by anytlt Party oT ATmboemd,Oo d Mglo—ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER REICLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT. AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER Arrangement and Format of the 2018 IPC The format of the IPC allows each chapter to be devoted to a particular subject with the exception of Chapter 3 which contains general subject matters that are not extensive enough to warrant their own independent chapter. Chapters Subjects 1-2 Administration and Definitions 3 General Regulations 4 Fixtures Faucets and Fixture Fittings 5 Water Heaters 6 Water Supply and Distribution 7 Sanitary Drainage 8 Indirect/Special Waste 9 Vents 10 Traps, Interceptors and Separators 11 Storm Drainage 12 Special Piping Medical Gas 13 Nonpotable Water Systems 14 Subsurface Landscape Irrigation Systems 15 Referenced Standards Appendices A-E Appendices The following is a chapter -by -chapter synopsis of the scope and intent of the provisions of the International Plumbing Code: Chapter 1 Scope and Administration. This chapter contains provisions for the application, enforcement and administration of subsequent requirements of the code. In addition to establishing the scope of the code, Chapter 1 identifies which buildings and structures come under its purview. Chapter 1 is largely concerned with maintaining "due process of law" in enforcing the requirements contained in the body of this code. Only through careful observation of the administrative provisions can the code official reasonably expect to demonstrate that "equal protection under the law" has been provided. Chapter 2 Definitions. Chapter 2 is the repository of the definitions of terms used in the body of the code. Codes are technical documents and every word, term and punctuation mark can impact the meaning of the code text and the intended results. The code often uses terms that have a unique meaning in the code and the code meaning can differ substantially from the ordinarily understood meaning of the term as used outside of the code. The terms defined in Chapter 2 are deemed to be of prime importance in establishing the meaning and intent of the code text that uses the terms. The user of the code should be familiar with and consult this chapter because the definitions are essential to the correct interpretation of the code and because the user may not be aware that a term is defined. Where understanding of a term's definition is especially key to or necessary for understanding of a particular code provision, the term is shown in italics. This is true only for those terms that have a meaning that is unique to the code. In other words, the generally understood meaning of a term or phrase might not be sufficient or consistent with the meaning prescribed by the code; therefore, it is essential that the code -defined meaning be known. Guidance regarding tense, gender and plurality of defined terms as well as guidance regarding terms not defined in this code is provided. 2018 INTERNATIONAL PLUMBING CODE 11 (ATFIgbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(R dme pooch od om).(Dby of PnmdNmod)Odo,Nomb,,x1ooe1voM 01 JM 15. xm.o oc ae AM (PET) Mt,b,mt to Lie Ag,, ^®'^Rt, ICC No fwN¢[TAodomoo.m AtO, goodomo- by anytlt Party o, Axmboemd,Oo d Mglo—ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER REICLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT. AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER Chapter 3 General Regulations. The content of Chapter 3 is often referred to as "miscellaneous," rather than general regulations. This is the only chapter in the code whose requirements do not interrelate. If a requirement cannot be located in another chapter, it should be located in this chapter. Chapter 3 contains safety requirements for the installation of plumbing and nonplumbing requirements for all types of fixtures. This chapter also has requirements for the identification of pipe, pipe fittings, traps, fixtures, materials and devices used in plumbing systems. The safety requirements of this chapter provide protection for the building's structural members, as well as prevent undue stress and strain on pipes. The building's structural stability is protected by the regulations for cutting and notching of structural members. Additional protection for the building occupants includes requirements to maintain the plumbing in a safe and sanitary condition, as well as privacy for those occupants. Chapter 4 Fixtures, Faucets and Fixture Fittings. This chapter regulates the minimum number of plumbing fixtures that must be provided for every type of building. This chapter also regulates the quality of fixtures and faucets by requiring those items to comply with nationally recognized standards. Because fixtures must be properly installed so that they are usable by the occupants of the building, this chapter contains the requirements for the installation of fixtures. Because the requirements for the number of plumbing fixtures affects the design of a building, Chapter 29 of the International Building Code (IBC) includes, verbatim, many of the requirements listed in Chapter 4 of this code. Chapter 5 Water Heaters. Chapter 5 regulates the design, approval and installation of water heaters and related safety devices. The intent is to minimize the hazards associated with the installation and operation of water heaters. Although this code does not regulate the size of a water heater, it does regulate all other aspects of the water heater installation such as temperature and pressure relief valves, safety drip pans, installation and connections. Where a water heater also supplies water for space heating, this chapter regulates the maximum water temperature supplied to the water distribution system. Chapter 6 Water Supply and Distribution. This chapter regulates the supply of potable water from both public and individual sources to every fixture and outlet so that it remains potable and uncontaminated. Chapter 6 also regulates the design of the water distribution system, which will allow fixtures to function properly and also help prevent backflow conditions. The unique requirements of the water supply for health care facilities are addressed separately. It is critical that the potable water supply system remain free of actual or potential sanitary hazards by providing protection against backflow. Chapter 7 Sanitary Drainage. The purpose of Chapter 7 is to regulate the materials, design and installation of sanitary drainage piping systems as well as the connections made to the system. The intent is to design and install sanitary drainage systems that will function reliably, that are neither undersized nor oversized and that are constructed from materials, fittings and connections as prescribed herein. This chapter addresses the proper use of fittings for directing the flow into and within the sanitary drain piping system. Materials and provisions necessary for servicing the drainage system are also included in this chapter. 2018 INTERNATIONAL PLUMBING CODE 12 CITFIgbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,d—od om).(Qty of IFnmd—od)Odo,Nomb,,x1ooe1voM 01 JM 15. xm.o oc ae AM (PET) Mt,—t to LET Ag,,—®'^Rt, ICC No fwN¢[TAodomoo.m AtO, Tgoodomo- by anytlt Party oT ATmboem-thowd Mglo—ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER REICLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT. AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER Chapter 8 Indirect/Special Waste. This chapter regulates drainage installations that require an indirect connection to the sanitary drainage system. Fixtures and plumbing appliances, such as those associated with food preparation or handling, health care facilities and potable liquids, must be protected from contamination that can result from connection to the drainage system. An indirect connection prevents sewage from backing up into a fixture or appliance, thus providing protection against potential health hazards. The chapter also regulates special wastes containing hazardous chemicals. Special waste must be treated to prevent any damage to the sanitary drainage piping and to protect the sewage treatment processes. Chapter 9 Vents. Chapter 9 covers the requirements for vents and venting. Knowing why venting is required makes it easier to understand the intent of this chapter. Venting protects every trap against the loss of its seal. Provisions set forth in this chapter are geared toward limiting the pressure differentials in the drainage system to a maximum of 1 inch of water column (249 Pa) above or below atmospheric pressure (i.e., positive or negative pressures). Chapter 10 Traps, Interceptors and Separators. This chapter contains design requirements and installation limitations for traps. Prohibited types of traps are specifically identified. Where fixtures do not frequently replenish the water in traps, a method is provided to ensure that the water seal of the trap will be maintained. Requirements for the design and location of various types of interceptors and separators are provided. Specific venting requirements are given for separators and interceptors as those requirements are not addressed in Chapter 9. Chapter 11 Storm Drainage. Chapter 11 regulates the removal of storm water typically associated with rainfall. The proper installation of a storm drainage system reduces the possibility of structural collapse of a flat roof, prevents the leakage of water through the roof, prevents damage to the footings and foundation of the building and prevents flooding of the lower levels of the building. Chapter 12 Special Piping and Storage Systems. This chapter contains the requirements for the design, installation, storage, handling and use of nonflammable medical gas systems, including inhalation anesthetic and vacuum piping systems, bulk oxygen storage systems and oxygen -fuel gas systems used for welding and cutting operations. The intent of these requirements is to minimize the potential fire and explosion hazards associated with the gases used in these systems. Chapter 13 Nonpotable Water Systems. This chapter regulates the design and installation of nonpotable water systems. The reduction of potable water use in buildings has led building designers in some jurisdictions to use nonpotable water for irrigation and flushing of water closets and urinals. This chapter provides the overall requirements for these systems. Chapter 14 Subsurface Landscape Irrigation Systems. This chapter regulates the design and installation of subsurface landscape irrigation systems for the disposal of on -site nonpotable water such as graywater. The reduction of potable water use in buildings has led building designers in some jurisdictions to use on -site nonpotable water for irrigation. This chapter provides the overall requirements for these systems. 2018 INTERNATIONAL PLUMBING CODE 13 CITFIgbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,dv od om).(Qty of PnmdNmod)Odo,Nomb,,x1ooe1voM 01 JM 15. xm.o oc ae AM (PET) Mt,b,mt to LET Ag,, ^®'^Rt, ICC No fwN¢[TAodomo,,m AtO, Tgoodomo- by anytlt Party oT ATmboemd,Oo d Mglo—ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER REICLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT. AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER Chapter 15 Referenced Standards. Chapter 15 contains a comprehensive list of all standards that are referenced in the code. The standards are part of the code to the extent of the reference to the standard. Compliance with the referenced standard is necessary for compliance with this code. By providing specifically adopted standards, the construction and installation requirements necessary for compliance with the code can be readily determined. The basis for code compliance is, therefore, established and available on an equal basis to the code official, contractor, designer and owner. Chapter 15 is organized in a manner that makes it easy to locate specific standards. It lists all of the referenced standards, alphabetically, by acronym of the promulgating agency of the standard. Each agency's standards are then listed in either alphabetical or numeric order based upon the standard identification. The list also contains the title of the standard; the edition (date) of the standard referenced; any addenda included as part of the ICC adoption; and the section or sections of this code that reference the standard. Appendix A Plumbing Permit Fee Schedule. Appendix A provides a format for a fee schedule. Appendix B Rates of Rainfall for Various Cities. Appendix B provides specific rainfall rates for major cities in the United States. Appendix C Structural Safety. Appendix C is provided so that the user does not have to refer to another code book for limitations for cutting, notching and boring of sawn lumber and cold - formed steel framing. Appendix D Degree Day and Design Temperatures. This appendix provides valuable temperature information for designers and installers of plumbing systems in areas where freezing temperatures might exist. Appendix E Sizing of Water Piping System. Appendix E provides two recognized methods for sizing the water service and water distribution piping for any structure. The method under Section E103 provides friction loss diagrams which require the user to "plot' points and read values from the diagrams in order to perform the required calculations and necessary checks. This method is the most accurate of the two presented in this appendix. The method under Section E201 is known to be conservative; however, very few calculations are necessary in order to determine a pipe size that satisfies the flow requirements of any application. 2018 INTERNATIONAL PLUMBING CODE 14 CopyngbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,d—od om).(Qty of IFnmd—od)Odo,Nomb,,x1ooe1voM 01 JM 15. xm.o oc ae AM (PET) Mt,—t to LET Ag,,—®'^Rt, ICC No fwN¢[TAodomo,,m AtO, Tgoodomo- by anytlt Party oT ATmboem-thowd Mglo—ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER REICLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT.

Seepage trench excavations shall be not less than 1 foot (304 mm) in width and not greater than 5 feet (1524 mm) in width. Trench excavations shall be spaced not less than 2 feet (610 mm) apart. The soil absorption area of a seepage trench shall be computed by using the bottom of the trench area (width) multiplied by the length of pipe. Individual seepage trenches shall be not greater than 100 feet (30 480 mm) in developed length. 1403.1.3 Seepage bed excavations. Seepage bed excavations shall be not less than 5 feet (1524 mm) in width and have more than one distribution pipe. The absorption area of a seepage bed shall be computed by using the bottom of the trench area. Distribution piping in a seepage bed shall be uniformly spaced not greater than 5 feet (1524 mm) and not less than 3 feet (914 mm) apart, and greater than 3 feet (914 mm) and not less than 1 foot (305 mm) from the sidewall or headwall. 1403.1.4 Excavation and construction. The bottom of a trench or bed excavation shall be level. Seepage trenches or beds shall not be excavated where the soil is so wet that such material rolled between the hands forms a soil wire. AII-smeared or compacted soil surfaces in the sidewalls or bottom of seepage trench or -bed excavations shall be scarified to the depth of smearing or compaction and the loose material removed. Where rain falls on an open excavation, the soil shall be left until sufficiently dry so a soil wire will not form when soil from the excavation bottom is rolled between the hands. The bottom area shall then be scarified and loose material removed. 1403.1.5 Aggregate and backfill. Not less than 6 inches in depth of aggregate, ranging in size from / to 2 / inches (12.7 mm z z to 64 mm), shall be laid into the trench below the distribution piping elevation. The aggregate shall be evenly distributed not less than 2 inches (51 mm) in depth over the top of the distribution pipe. The aggregate shall be covered with approved synthetic materials or 9 inches (229 mm) of uncompacted marsh hay or straw. Building paper shall not be used to cover the aggregate. Not less than 9 inches (229 mm) of soil backfill shall be provided above the covering. 1403.2 Distribution piping. Distribution piping shall be not less than 3 inches (76 mm) in diameter. Materials shall comply with Table 1403.2. The top of the distribution pipe shall be not less than 8 inches (203 mm) below the original surface. The slope of the distribution pipes shall be not less than 2 inches (51 mm) and not greater than 4 inches (102 mm) per 100 feet (30 480 mm).

AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER APPENDIX E SIZING OF WATER PIPING SYSTEM The provisions contained in this appendix are not mandatory unless specifically referenced in the adopting ordinance. User note: About this appendix. The sizing of water service and water distribution piping is not specified in Chapter 6 as it is left up to the designer of the system with the code official approving the design method. Appendix E provides several methods that could be used by a system designer. SECTION E101 GENERAL E101.1 Scope. E101.1.1 This appendix outlines two procedures for sizing a water piping system (see Sections E103.3 and E201.1). The design procedures are based on the minimum static pressure available from the supply source, the head changes in the system caused by friction and elevation, and the rates of flow necessary for operation of various fixtures. E101.1.2 Because of the variable conditions encountered in hydraulic design, it is impractical to specify definite and detailed rules for sizing of the water piping system. Accordingly, other sizing or design methods conforming to good engineering practice standards are acceptable alternatives to those presented herein. SECTION E102 INFORMATION REQUIRED E102.1 Preliminary. Obtain the necessary information regarding the minimum daily static service pressure in the area where the building is to be located. If the building supply is to be metered, obtain information regarding friction loss relative to the rate of flow for meters in the range of sizes likely to be used. Friction loss data can be obtained from most manufacturers of water meters. E102.2 Demand load. Ell 02.2.1 Estimate the supply demand of the building main and the principal branches and risers of the system by totaling the corresponding demand from the applicable part of Table E103.3(3). E102.2.2 Estimate continuous supply demands in gallons per minute (L/m) for items such as lawn sprinklers; and air conditioners, et- and add the sum to the total demand for fixtures. The result is the estimated supply demand for the building supply. 2018 INTERNATIONAL PLUMBING CODE 291 CopyngbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,d—od om).(Qty of IFnmd—od)Odo,Nomb,,x1ooe1voM 01 JM 15. x m.o oc ae AM (PET) Mt,—t to LET Ag,,—®'^Rt, ICC No fwN¢[TAodomoo.m AtO, Tgoodomo- by anytlt Party oT ATmboem-thowd Mglo—ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER REICLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT. AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER SECTION E103 SELECTION OF PIPE SIZE E103.1 General. Decide from Table 604.3 what is the desirable minimum residual pressure that should be maintained at the highest fixture in the supply system. If the highest group of fixtures contains flushometer valves, the pressure for the group should be not less than 15 pounds per square inch (psi) (103.4 kPa) flowing. For flush tank supplies, the available pressure should be not less than 8 psi (55.2 kPa) flowing, except blowout action fixtures must be not less than 25 psi (172.4 kPa) flowing. E103.2 Pipe sizing. El03.2.1 Pipe sizes can be selected according to the following procedure or by other design methods conforming to acceptable engineering practice and approved by the administrative authority. The sizes selected must not be less than the minimum required by this code. E103.2.2 Water pipe sizing procedures are based on a system of pressure requirements and losses, the sum of which must not exceed the minimum pressure available at the supply source. These pressures are as follows: 1. Pressure required at fixture to produce required flow. See Sections 604.3 and 604.5. 2. Static pressure loss or gain (due to head) is computed at 0.433 psi per foot (9.8 kPa/m) of elevation change. Example: Assume that the highest fixture supply outlet is 20 feet (6096 mm) above or below the supply source. This produces a static pressure differential of 20 feet by 0.433 psi/foot (2096 mm by 9.8 kPa/m) and an 8.66 psi (59.8 kPa) loss. 3. Loss through water meter. The friction or pressure loss can be obtained from meter manufacturers. 4. Loss through taps in water main. 5. Losses through special devices such as filters, softeners, backflow prevention devices and pressure regulators. These values must be obtained from the manufacturers. 6. Loss through valves and fittings. Losses for these items are calculated by converting to equivalent length of piping and adding to the total pipe length. 2018 INTERNATIONAL PLUMBING CODE 292 CopyngbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,d—od om).(Qty of IFnmd—od)Odo,Nomb,,x1ooe1voM 01 JM 15. x m.o oc ae AM (PET) Mt,—t to LET Ag,,—®'^Rt, ICC No fwN¢[TAodomoo.m AtO, Tgoodomo- by anytlt Party oT ATmboem-thowd Mglo—ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER REICLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT. AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER Loss due to pipe friction can be calculated whegm the pipe size, the pipe length and the flow through the pipe are known. With these three items, the friction loss can be determined. For piping flow charts not included, use manufacturers' tables and velocity recommendations. Note: For the purposes of all examples, the following metric conversions are applicable: 1 cubic foot per minute = 0.4719 L/s 2 1 square foot = 0.0929 m 1 degree = 0.0175 rad 1 pound per square inch = 6.895 kPa 1 inch = 25.4 mm 1 foot = 304.8 mm 1 gallon per minute = 3.785 L/m E103.3 Segmented loss method. The size of water service mains, branch mains and risers by the segmented loss method must be determined according to water supply demand [gpm (L/m)], available water pressure [psi (kPa)] and friction loss caused by the water meter and developed length of pipe [feet (m)], including equivalent length of fittings. This design procedure is based on the following parameters: Calculates the friction loss through each length of the pipe. Based on a system of pressure losses, the sum of which must not exceed the minimum pressure available at the street main or other source of supply. Pipe sizing based on estimated peak demand, total pressure losses caused by difference in elevation, equipment, developed length and pressure required at most remote fixture, loss through taps in water main, losses through fittings, filters, backflow prevention devices, valves and pipe friction. Because of the variable conditions encountered in hydraulic design, it is impractical to specify definite and detailed rules for sizing of the water piping system. Current sizing methods do not address the differences in the probability of use and flow characteristics of fixtures between types of occupancies. Creating an exact model of predicting the demand for a building is impossible and final studies assessing the impact of water conservation on demand are not yet complete. The following steps are necessary for the segmented loss method. 2018 INTERNATIONAL PLUMBING CODE 293 (ATFIgbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,d—od om).(Qty of IFnmd—od)Odo,Nomb,,x1ooe1voM 01 JM 15. xm.o oc ae AM (PET) Mt,—t to LET Ag,,—®'^Rt, ICC No fwN¢[TAodomoo.m AtO, Tgoodomo- by anytlt Party oT ATmboem-thowd Mglo—ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER REICLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT. AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER Preliminary. Obtain the necessary information regarding the minimum daily static service pressure in the area where the building is to be located. If the building supply is to be metered, obtain information regarding friction loss relative to the rate of flow for meters in the range of sizes to be used. Friction loss data can be obtained from manufacturers of_ water meters. It is essential that enough pressure be available to overcome all system losses caused by friction and elevation so that plumbing fixtures operate properly. Section 604.6 requires the water -distribution system to be designed for the minimum pressure available taking into consideration pressure fluctuations. The lowest pressure must be selected to guarantee a continuous, adequate supply of water. The lowest pressure in the public main usually -occurs in the summer because of lawn sprinkling and: supplying water for air-conditioning cooling towers. Future demands placed on the public main as a result of large growth or expansion should also be considered. The available pressure will decrease as additional loads are placed on the public system. 2. Demand load. Estimate the supply demand of the building main and the principal branches and risers of the system by totaling the corresponding demand from the applicable part of Table El03.3(3). When estimating peak demand sizing methods typically use water supply fixture units (w.s.f.u.) [see Table E103.3(2)]. This numerical factor measures the load - producing effect of a single plumbing fixture of a given kind. The use of such fixture units can be applied to a single basic probability curve (or table), found in the various sizing methods [Table E103.3(3)]. The fixture units are then converted into gallons per minute (L/m) flow rate for estimating demand. 2.1. Estimate continuous supply demand in gallons per minute (L/m) for items such as lawn sprinklers; and air conditioners, etG—., and add the sum to the total demand for fixtures. The result is the estimated supply demand for the building supply. Fixture units cannot be applied to constant use fixtures such as hose bibbs, lawn sprinklers and air conditioners. These types of fixtures must be assigned the gallon per minute (L/m) value. 3. Selection of pipe size. This water pipe sizing procedure is based on a system of pressure requirements and losses, the sum of which must not exceed the minimum pressure available at the supply source. These pressures are as follows: 3.1. Pressure required at the fixture to produce required flow. See Sections 604.3 and 604.5. 3.2. Static pressure loss or gain (because of head) is computed at 0.433 psi per foot (9.8 kPa/m) of elevation change. 3.3. Loss through a water meter. The friction or pressure loss can be obtained from the manufacturer. 3.4. Loss through taps in water main [see Table El03.3(4)]. 2018 INTERNATIONAL PLUMBING CODE 294 CopyngbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,dv od om).(Qty of PnmdNmod)Odo,Nomb,,x1ooe1voM 01 JM 15. xm.o oc ae AM (PET) Mt,b,mt to LET Ag,, ^®'^Rt, ICC No fwN¢[TAodomoo.m AtO, Tgoodomo- by anytlt Party oT ATmboemd,Oo d Mglo—ody oTyncg and Nyodwg LARISd ANY VNAVTHO RIVER REICLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT. AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER 3.5. Losses through special devices such as filters, softeners, backflow prevention devices and pressure regulators. These values must be obtained from the manufacturers. 3.6. Loss through valves and fittings [see Tables E103.3(5) and E103.3(6)]. Losses for these items are calculated by converting to equivalent length of piping and adding to the total pipe length. 3.7. Loss caused by pipe friction can be calculated whe44m the pipe size, the pipe length and the flow through the pipe are known. With these three items, the friction loss -can be determined using Figures E103.3(2) through E103.3(7). When using charts, use pipe inside diameters. For piping flow charts not included, use manufacturers' tables and velocity recommendations. Before attempting to size any water supply system, it is necessary to gather preliminary information that includes available pressure, piping material, select design velocity, elevation differences and developed length to most remote fixture. The water supply system is divided into sections at major changes in elevation or where branches lead to fixture groups. The peak demand must be determined in each part of the hot and cold water supply system whishlhal includes the corresponding water supply fixture unit and conversion to gallons per minute (Um) flow rate to be expected through each section. Sizing methods require the determination of the "most hydraulically remote" fixture to compute the pressure loss caused by pipe and fittings. The hydraulically remote fixture represents the most downstream fixture along the -circuit of piping requiring the most available pressure to operate properly. Consideration must be given to all pressure demands and losses, such as friction caused by pipe, fittings and equipment, elevation and the residual pressure required by Table 604.3. The two most common and frequent complaints about the water supply system operation are lack of adequate pressure and noise. Problem: What size Type L copper water pipe, service and distribution will be required to serve a two-story factory building having on each floor, back-to-back, two toilet rooms each equipped with hot and cold water? The highest fixture is 21 feet (6401 mm) above the street main, which is tapped with a 2-inch (51 mm) corporation cock at which point the minimum pressure is 55 psi (379.2 kPa). In the building basement, a 2-inch (51 mm) meter with a maximum pressure drop of 11 psi (75.8 kPa) and 3-inch (76 mm) reduced pressure principle backflow preventer with a maximum pressure drop of 9 psi (621 kPa) are to be installed. The system is shown by Figure El03.3(1). To be determined are the pipe sizes for the service main and the cold and hot water distribution pipes. Solution: A tabular arrangement such as shown in Table E103.3(1) should first be constructed. The steps to be followed are indicated by the tabular arrangement itself as they are in sequence, Columns 1 through 10 and Lines A through L. Step 1 Columns 1 and 2: Divide the system into sections breaking at major changes in elevation or where branches lead to fixture groups. After point B [see Figure El03.3(1)], separate consideration will be given to the hot and cold water piping. Enter the sections to be considered in the service and cold water piping in Column 1 of the tabular arrangement. Column 1 of Table E103.3(1) provides a line -by-line recommended tabular arrangement for use in solving pipe sizing. 2018 INTERNATIONAL PLUMBING CODE 295 (ATFIgbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,dv od om).(Qty of PnmdNmod)Odo,Nomb,,x1ooe1voM 01 JM 15. xm.o oc ae AM (PET) Mt,b,mt to LET Ag,, ^®'^Rt, ICC No fwN¢[TAodomoo.m AtO, Tgoodomo- by anytlt Party oT ATmboemd,Oo d Mglo—ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER REICLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT. AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER The objective in designing the water supply system is to ensure an adequate water supply and pressure to all fixtures and equipment. Column 2 provides the pounds per square inch (psi) to be considered separately from the minimum pressure available at the main. Losses to take into consideration are the following: the differences in elevation between the water supply source and the highest water supply outlet, meter pressure losses, the tap in main loss, special fixture devices such as water softeners and backflow prevention devices and the pressure required at the most remote fixture outlet. The difference in elevation can result in an increase or decrease in available pressure at the main. Where the water supply outlet is located above the source, this results in a loss in the available pressure and is subtracted from the pressure at the water source. Where the highest water supply outlet is located below the water supply source, there will be an increase in pressure that is added to the available pressure of the water source. Column 3: According to Table El03.3(3), determine the gpm (L/m) of flow to be expected in each section of the system. These flows range from 28.6 to 108 gpm. Load values for fixtures must be determined as water supply fixture units and then converted to a gallon - per -minute (gpm) rating to determine peak demand. When calculating peak demands, the water supply fixture units are added and then converted to the gallon -per -minute rating. For continuous flow fixtures such as hose bibbs and lawn sprinkler systems, add the gallon -per - minute demand to the intermittent demand of fixtures. For example, a total of 120 water supply fixture units is converted to a demand of 48 gallons per minute. Two hose bibbs X 5 gpm demand = 10 gpm. Total gpm rating = 48.0 gpm + 10 gpm = 58.0 gpm demand. Step 2 Line A: Enter the minimum pressure available at the main source of supply in Column 2. This is 55 psi (379.2 kPa). The local -water authorities generally keep records of pressures at different times of day and year. The available pressure can also be checked from nearby buildings or from fire department hydrant checks. Line B: Determine from Table 604.3 the highest pressure required for the fixtures on the system, which is 15 psi (103.4 kPa), to operate a flushometer valve. The most remote fixture outlet is necessary to compute the pressure loss caused by pipe and fittings, and represents the most downstream fixture along the circuit of piping requiring the available pressure to operate properly as indicated by Table 604.3. Line C: Determine the pressure loss for the meter size given or assumed. The total water flow from the main through the service as determined in Step 1 will serve to aid in the meter selected. There are three common types of water meters; the pressure losses are determined by the American Water Works Association Standards for displacement type, compound type and turbine type. The maximum pressure loss of such devices takes into consideration the meter size, safe operating capacity (gpm) and maximum rates for continuous operations (gpm). Typically, equipment imparts greater pressure losses than piping. Line D: Select from Table E103.3(4) and enter the pressure loss for the tap size given or assumed. The loss of pressure through taps and tees in pounds per square inch (psi) is based on the total gallon -per -minute flow rate and size of the tap. 2018 INTERNATIONAL PLUMBING CODE 296 CopyngbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,dv od om).(Qty of PnmdNmod)Odo,Nomb,,x1ooe1voM 01 JM 15. xm.o oc ae AM (PET) Mt,b,mt to LET Ag,, ^®'^Rt, ICC No fwN¢[TAodomoo.m AtO, Tgoodomo- by anytlt Party oT ATmboemd,Oo d Mglo—ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER REICLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT. AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER Line E: Determine the difference in elevation between the main and source of supply and the highest fixture on the system. Multiply this figure, expressed in feet, by 0.43 psi (2.9 kPa). Enter the resulting psi loss on Line E. The difference in elevation between the water supply source and the highest water supply outlet has a significant impact on the sizing of the water supply system. The difference in elevation usually results in a loss in the available pressure because the water supply outlet is generally located above the water supply source. The loss is caused by the pressure required to lift the water to the outlet. The pressure loss is subtracted from the pressure at the water source. Where the highest water supply outlet is located below the water source, there will be an increase in pressure that is added to the available pressure of the water source. Lines F, G and H: The pressure losses through filters, backflow prevention devices or other special fixtures must be obtained from the manufacturer or estimated and entered on these lines. Equipment such as backflow prevention devices, check valves, water softeners, instantaneous or tankless water heaters, filters and strainers can impart a much greater pressure loss than the piping. The pressure losses can range from 8 psi to 30 psi. Step 3 Line I: The sum of the pressure requirements and losses that affect the overall system (Lines B through H) is entered on this line. Summarizing the steps, all of the system losses are subtracted from the minimum water pressure. The remainder is the pressure available for friction, defined as the energy available to push the water through the pipes to each fixture. This force can be used as an average pressure loss, as long as the pressure available for friction is not exceeded. Saving a certain amount for available water supply pressures as an area incurs growth, or because of aging of the pipe or equipment added to the system is recommended. Step 4 Line J: Subtract Line I from Line A. This gives the pressure that remains available from overcoming friction losses in the system. This figure is a guide to the pipe size that is chosen for each section, incorporating the total friction losses to the most remote outlet (measured length is called developed length). Exception: Wheals the main is above the highest fixture, the resulting psi must be considered a pressure gain (static head gain) and omitted from the sums of Lines B through H and added to Line J. The maximum friction head loss that can be tolerated in the system during peak demand is the difference between the static pressure at the highest and most remote outlet at no -flow conditions and the minimum flow pressure required at that outlet. If the losses are within the required limits, then every run of pipe will alse be within the required friction head loss. Static pressure loss is the most remote outlet in feet X 0.433 = loss in psi caused by elevation differences. Step 5 Column 4: Enter the length of each section from the main to the most remote outlet (at Point E). Divide the water supply system into sections breaking at major changes in elevation or where branches lead to fixture groups. 2018 INTERNATIONAL PLUMBING CODE 297 CopyngbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,dv od om).(Qty of PnmdNmod)Odo,Nomb,,x1ooe1voM 01 JM 15. xm.o oc ae AM (PET) Mt,b,mt to LET Ag,, ^®'^Rt, ICC No fwN¢[TAodomo,,m AtO, Tgoodomo- by anytlt Party oT ATmboemd,Oo d Mglo—ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER REICLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT. AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER Step 6 Step 7 E103.3.3. Selection of pipe size, Step 6 Column 5: When selecting a trial pipe size, the length from the water service or meter to the most remote fixture outlet must be measured to determine the developed length. However, in systems having a flushometer valve or temperature controlled shower at the topmost floors the developed length would be from the water meter to the most remote flushometer valve on the system. A rule of thumb is that size will become progressively smaller as the system extends farther from the main source of supply. Trial pipe size may be arriyeda�he following formula is an acceptable method to determine trial nine size: Line J: (Pressure available to overcome pipe friction) X 100/equivalent length of run total developed length to most remote fixture X percentage factor of 1.5 (note: a percentage factor is used only as an estimate for friction losses imposed for fittings for initial trial pipe size) = psi (average pressure drops per 100 feet of pipe). For trial pipe size, see Figure E 103.3(3) (Type L copper) based on 2.77 psi and a 108 1 gpm = 2 / inches. To determine the equivalent length of run to the most remote outlet, 2 the developed length is determined and added to the friction losses for fittings and valves. The developed lengths of the designated pipe sections are as follows: A-B 54ft B-C 8ft C-D 13ft D -E 150ft Total developed length = 225 ft The equivalent length of the friction loss in fittings and valves must be added to the developed length (most remote outlet). Where the size of fittings and valves is not known, the added friction loss should be approximated. A general rule that has been used is to add 50 percent of the developed length to allow for fittings and valves. For example, the equivalent length of run equals the developed length of run (225 ft X 1.5 = 338 ft). The total equivalent length of run for determining a trial pipe size is 338 feet. Example: 9.36 (pressure available to overcome pipe friction) X 100/338 (equivalent length of run = 225 X 1.5) = 2.77 psi (average pressure drop per 100 feet of pipe). Column 6: Select from Table El03.3(6) the equivalent lengths for the trial pipe size of fittings and valves on each pipe section. Enter the sum for each section in Column 6. (The number of fittings to be used in this example must be an estimate.) The equivalent length of piping is the developed length plus the equivalent lengths of pipe corresponding to friction head losses for fittings and valves. Where the size of fittings and valves is not known, the added friction head losses must be approximated. An estimate for this example is found in Table E.1. 2018 INTERNATIONAL PLUMBING CODE 298 CopyngbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,d—od om).(Qty of IFnmd—od)Odo,Nomb,,x1ooe1voM 01 JM 15. xm.o oc ae AM (PET) Mt,—t to LET Ag,,—®'^^I, ICC No fwN¢[TAodomoo.m AtO, Tgoodomo- by anytlt Party oT ATmboem-thowd Mglo—ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER REICLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT. AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER Step 8 Step 9 Column 7: Add the figures from Column 4 and Column 6, and enter in Column 7. Express the sum in hundreds of feet. Column 8: Select from Figure El03.3(3) the friction loss per 100 feet (30 480 mm) of pipe for the gallon -per -minute flow in a section (Column 3) and trial pipe size (Column 5). Maximum friction head loss per 100 feet is determined on the basis of total pressure available for friction head loss and the longest equivalent length of run. The selection is based on the gallon -per -minute demand, the uniform friction head loss and the maximum design velocity. Where the size indicated by hydraulic table indicates a velocity in excess of the selected velocity, a size must be selected that produces the required velocity. Step 10 Column 9: Multiply the figures in Columns 7 and 8 for each section and enter in Column 9. Total friction loss is determined by multiplying the friction loss per 100 feet (30 480 mm) for each pipe section in the total developed length by the pressure loss in fittings expressed as equivalent length in feet. Note: Section C-F should be considered in the total pipe friction losses only if greater loss occurs in Section C-F than in pipe section D- E. Section C-F is not considered in the total developed length. Total friction loss in equivalent length is determined in Table E.2. Step 11 Line K: Enter the sum of the values in Column 9. The value is the total friction loss in equivalent length for each designated pipe section. Step 12 Line L: Subtract Line J from Line K and enter in Column 10. The result should always be a positive or plus figure. If it is not, repeat the operation using Columns 5, 6, 8 and 9 until a balance or near balance is obtained. If the difference between Lines J and K is a high positive number, it is an indication that the pipe sizes are too large and should be reduced, thus saving materials. In such a case, the operations using Columns 5, 6, 8 and 9 should again be repeated. The total friction losses are determined and subtracted from the pressure available to overcome pipe friction for trial pipe size. This number is critical as it provides a guide to whether the pipe size selected is too large and the process shouldbe repeated to obtain an economically designed system. 2018 INTERNATIONAL PLUMBING CODE 299 CopyngbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,d—od om).(Qty of IFnmd—od)Odo,Nomb,,x1ooe1voM 01 JM 15. xm.o oc ae AM (PET) Mt,—t to LET Ag,,—®'^Rt, ICC No fwN¢[TAodomoo.m AtO, Tgoodomo- by anytlt Party oT ATmboem-thowd Mglo—ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER REICLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT.

AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER SECTION E201 SELECTION OF PIPE SIZE E201.1 Size of water service mains, branch mains and risers. 3 The minimum size water service pipe shall be / inch (19.1 mm). The size of water service mains, branch mains and risers shall be determined according to water supply demand [gpm (L/m)], available water pressure [psi (kPa)] and friction loss due to the water meter and developed length of pipe [feet (m)], including equivalent length of fittings. The size of each water distribution system shall be determined according to the procedure outlined in this section or by other design methods conforming to acceptable engineering practice and approved by the code official: 1. Supply load in the building water distribution system shall be determined by total load on the pipe being sized, in terms of water -supply fixture units (w.s.f.u.), as shown in Table El03.3(2). For fixtures not listed, choose a w.s.f.u. value of a fixture with similar flow characteristics. 2. Obtain the minimum daily static service pressure [psi (kPa)] available (as determined by the local water authority) at the water meter or other source of supply at the installation location. Adjust this minimum daily static pressure [psi (kPa)] for the following conditions: 2.1. Determine the difference in elevation between the source of supply and the highest water supply outlet. Where the highest water supply outlet is located above the source of supply, deduct 0.5 psi (3.4 kPa) for each foot (0.3 m) of difference in elevation. Where the highest water supply outlet is located below the source of supply, add 0.5 psi (3.4 kPa) for each foot (0.3 m) of difference in elevation. 2.2. Where a water pressure -reducing valve is installed in the water distribution system, the minimum daily static water pressure available is 80 percent of the minimum daily static water pressure at the source of supply or the set pressure downstream of the pressure -reducing valve, whichever is smaller. 2.3. Deduct all pressure losses due to special equipment such as a backflow preventer, water filter and water softener. Pressure loss data for each piece of equipment shall be obtained through the manufacturer of such devices. 2.4. Deduct the pressure in excess of 8 psi (55 kPa) due to installation of the special plumbing fixture, such as temperature controlled shower and flushometer tank water closet. Using the resulting minimum available pressure, find the corresponding pressure range in Table E201.1. 3. The maximum developed length for water piping is the actual length of pipe between the source of supply and the most remote fixture, including either hot (through the water heater) or cold water branches multiplied by a factor of 1.2 to compensate for pressure loss through fittings. Select the appropriate column in Table E201.1 equal to or greater than the calculated maximum developed length. 2018 INTERNATIONAL PLUMBING CODE 315 CopyngbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,dv od om).(Qty of PnmdNmod)Odo,Nomb,,x1ooe1voM 01 JM 15. x m.o oc ae AM (PET) Mt,b,mt to LET Ag,, ^®'^^I, ICC No fwN¢[TAodomo,,m AtO, Tgoodomo- by anytlt Party oT ATmboemd,Oo d Mglo—ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER REICLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT.

To determine the size of water service pipe, meter and main distribution pipe to the building using the appropriate table, follow down the selected "maximum developed length" column to a fixture unit equal to, or greater than the total installation demand calculated by using the "combined" water supply fixture unit column of Table El03.3(2). Read the water service pipe and meter sizes in the first left-hand column and the main distribution pipe to the building in the second left-hand column on the same row. 5. To determine the size of each water distribution pipe, start at the most remote outlet on each branch (either hot or cold branch) and, working back toward the main distribution pipe to the building, add up the water supply fixture unit demand passing through each segment of the distribution system using the related hot or cold column of Table E103.3(2). Knowing demand, the size of each segment shall be read from the second left-hand column of the same table and maximum developed length column selected in Steps 1 and 2, under the same or next smaller size meter row.
