AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER Introduction Development PREFACE 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 com- patible with all of the International Codes" (I -Codes) published by the International Code Council° (ICC'), including the International Building Code°, International Energy Conservation Code', Inter- national Existing Building Code', International Fire Code°, International Fuel Gas Code°, Interna- tional Green Construction Code', International Mechanical Code', International Private Sewage Disposal Code', International Property Maintenance Code', International Residential Code°, Inter- national Swimming Pool and Spa Code', International Wildland-Urban Interface Code', Interna- tional 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, con- struction 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. In addition to the codes themselves, the code development process brings together building pro- fessionals 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. 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 par- ticular types or classes of materials, products or methods of construction. 2018 INTERNATIONAL PLUMBING CODE" I " ' (ATFIght @ 2017 ICC ALL RIGHTS RESERVED Awned by H®Ih¢ Van DmA(Rv dme Oo,dA od om),(Qty of FRmdNmod) O[do, N=b,, *1 008170DI 01 JM 15, m0 oc ss AM (PET) Mt,b,mt to ( LEA Ag,, ^®'^Rt, ICC No fwN¢[TAodomo,,m AtO, goodomo- by any Ot Party o, AAmboemd,Oo[vsd Mglo—ody oTyncg and Nyodwg LMARISAd ANY VNAVTHO RIVER REICLA VCTION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT. AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER Maintenance The International Plumbing Code is kept up to date through the review of proposed changes submit- ted by code enforcement officials, industry representatives, design professionals and other inter- ested 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 nomi- nated by the following industry partners and approved bythe 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) 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 devel- opment 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 consti- tutes a recommendation to the voting membership for final action on the proposed change. Pro- posed 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 sectionsthat have [BS] in front of them (e.g., [BS] 309.2) are considered bythe IBC —Structural Code Development Committee at the code development hearings. The bracketed letter designations for committees responsible for portions of this code are as fol- lows: [A] = Administrative Code Development Committee; [BE] = IBC —Egress Code Development Committee; [BG] = IBC —General Code Development Committee; IV 2018 INTERNATIONAL PLUMBING CODE® S ( firill ' UER CopynghtOo2.017 ICC ALL RIGHTS RESERVED A—LDd by H®Ih¢ Van DmA(Rvdme Oo,dA od om),(Qty of FRmdNmod)O[do,N=b,,*1008170DI 01 JM 15.

For the development of the 2021 edition of the I -Codes, there will be two groups of code devel- opment committees and they will meet in separate years. Note that these are tentative groupings. Group A Codes Group B Codes (Heard in 2018, Code Change Proposals (Heard in 2019, Code Change Proposals Deadline: January 8, 2018) Deadline: January 7, 2019) International Building Code Administrative Provisions (Chapter 1 of all — Egress (Chapters 10, 11, Appendix E) codes except IECC, IRC and IgCC, administra- - Fire Safety (Chapters 7, 8, 9, 14, 26) tive updates to currently referenced Stan- -General (Chapters 2-6, 12, 27-33, dards, and designated definitions) Appendices A, B, C, D, K, N) International Fire Code International Building Code —Structural (Chapters 15-25, Appendices F, G,H,I,1,L,M) International Fuel Gas Code International Existing Building Code International Mechanical Code International Energy Conservation Code — Commercial International Plumbing Code International Energy Conservation Code — Residential — IECC—Residential — IRC—Energy (Chapter 11) International Property Maintenance Code International Green Construction Code (Chapter 1) International Private Sewage Disposal Code International Residential Code — IRC—Building (Chapters 1-10, Appendices E, F, H,1, K, L, M, 0, 0, R, S, T) International Residential Code —IRC—Mechanical(Chapters 12-23) — IRC—Plumbing (Chapters 25-33, Appendices G, I, N, P) International Swimming Pool and Spa Code International Wildland-Urban Interface Code International Zoning Code Note: Proposed changesto the ICC Performance Code IN will be heard by the code development committee noted in brack- ets [ ] in the text of the ICC Performance Code IN Code change proposals submitted for code sections that have a letter designation in front of them will be heard by the respective committee responsible for such code sections. Because differ- ent committees hold Committee Action Hearings in different years, proposals for the PC 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 Resi- dential Code and International Green Construction Code. Therefore, any proposals received for Chapter 1 of this code will be assigned tothe Administrative Code Development Committee for con- sideration in 2019. It is very important that anyone submitting code change proposals understands which code development committee is responsible for the section of the code that is the subject of the code change proposal.

AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER 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 (M*) 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. Coordination of the International Codes Italicized Terms Adoption 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 pos- sible, 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. 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 defi- nitions apply. The words and terms selected have code -specific definitions that the user should read carefully to facilitate better understanding of the code. 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 for- mats. 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/pri- vate partnership for code development between jurisdictions and the ICC. The ICC also recognizes the need for jurisdictions to make laws available to the public. All I -Codes and I -Standards, along with the laws of many jurisdictions, are available for free in a nondownloadable form on the ICC's website. Jurisdictions should contact the ICC at adop- tions@iccsafe.org to learn how to adopt and distribute laws based on the International Plumb- ing Code in a manner that provides necessary access, while maintaining the ICC's copyright. 2018 INTERNAT10NAL PLUMBING CODE® (ATFIgbtOO?.o17 ICC ALL RIGHTS RESERVED A—LDd by HDO,, Van Dme(Rvdme pooch od om).(Qty of PnmdNmod)Odo,N=b,,*1008170DI 01 JM 15. xm.o oc 45 AM (PET) Mt,b,mt to Lie Ag,, ^®,At, ICC No fwN¢[TAodomo,,m ALO, goodomo- by any tlud Party o, Axmboem a Romsl Mglo—ody oTyncg andoNyb,IyogT,oIRb¢d ANY VNAVTHORIVED REICLA VCIION OR DISTRIBUTION IS A VIOLATION OF THE FEDERALCOPYRIGHTACT 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 mini- mum 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 wastewater 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 occu- pants 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 require- ments for providing safe water to a building as well as a safe manner in which liquid -borne wastes are carried away from a building. 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.

AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER 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 establish- ing the scope of the code, Chapter 1 identifies which buildings and structures come under its pur- view. 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 adminis- trative 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 mean- ing 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. Chapter 3 General Regulations. The content of Chapter 3 is often referred to as "miscella- neous," 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 mem- bers, as well as prevent undue stress and strain on pipes. The building's structural stability is pro- tected 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 condi- tion, as well as privacy for those occupants. Chapter 4 Fixtures, Faucets and Fixture Fittings. This chapter regulates the minimum num- ber of plumbing fixtures that must be provided for every type of building. This chapter also regu- lates 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 instal- lation 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 sup- plies water for space heating, this chapter regulates the maximum water temperature supplied to the water distribution system. 2018 INTERNATIONAL PLUMBING CODE CITFIgbtOO?.o17 ICC ALL RIGHTS RESERVED A—LDd by HDO,, Van Dme(Rvdme pooch od om).(Qty of PnmdNmod)Odo,N=b,,x1008170DI 01 JM 15. xm.o oc 45 AM (PET) LAt,—t to Lie Ag,, ^®'^Rt, ICC No fwN¢[TAodomo,,m AtO, goodomo- by anytlt Party o, Axmboem a Romsl Mglo—ody oT,,g and Nyodwg LMARISd 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 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 require- ments 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 protec- tion 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 pre- scribed 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 drain- age system are also included in this chapter. 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 indi- rect connection prevents sewage from backing up into a fixture or appliance, thus providing protec- tion 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 pres- sure 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 fix- tures 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 associ- ated 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 tothe footings and foundation of the building and prevents flooding of the lower levels of the build- ing. 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 design- ers in some jurisdictions to use nonpotable water for irrigation and flushing of water closets and uri- nals. 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 over- all requirements for these systems. 2018 INTERNAT10NAL PLUMBING CODe A I i l i CITFIghtOo2.017 ICC ALL RIGHTS RESERVED A—LDd by H®Ih¢ Van Dme(Rv dme pooch od om),(Qty of FRmdNmod)O[do,N=b,,*1008170DI 01 JM 15.

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 neces- sary 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 arethen listed in either alphabetical or numeric order based upon the stan- dard 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 tem- perature information for designers and installers of plumbing systems in areas where freezing tem- peratures 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. xii 2018 INTERNAT10NAL PLUMBING CODE rill l i CopynghtOo2.017 ICC ALL RIGHTS RESERVED A—LDd by H®Ih¢ Van DmA(Rv dme Oo,dA od om),(Qty of FRmdNmod)O[do,N=b,,*1008170DI 01 JM 15.

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. ElOLLl 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 unpractical 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 bwldmg 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. E102.2.1 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, and add the sum to the total demand for fixtures The result is the estimated supply demand for the building supply SECTION E103 SELECTION OF PIPE SIZE E103.1 General. Decide from Table 604 3 what is the desir- able 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. E103.2.1 Pipe sizes can be selected according to the fol- lowing procedure or by other design methods conform mg 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 sys- tem 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 gam (due to head) is com- puted 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, soft- eners, 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 7 Loss due to pipe friction can be calculated where 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 rec- ommendations Note: For the purposes of all examples, the fol- lowing metric conversions are applicable 1 cubic foot per minute = 0 4719 L/s 2018 INTERNAT10NAL PLUMBING CODE® 139 I I I I CITFIght @ 2017 ICC ALL RIGHTS RESERVED A—LDd by H®Ih¢ Van Dme(Rv dme Oo,dv od om),(Qtyof PnmdNmod) O,do, N=b¢ x1 00e170DI 01 JM 15, m0 oc ss AM (PET) tto ( Lie Affiee^® Rt,ICC NofwN¢[TAodomoo.m AtO,Pepeodomo- by any Ot Party o, Axmboemdm6o d Mglo—ody mpyncg and Nyodwg LARISAd ANY VNAVTHO RIVER REICLA VCTION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT.

The size of water service mains, branch mains and risers by the segmented loss method must be determmed 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 pro- cedure 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 hydrau- lic 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 assess- ing the impact of water conservation on demand are not yet complete The following steps are necessary for the seg- mented loss method 1 Preliminary. Obtain the necessary information regard - mg 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 mformation 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 consid- eration pressure fluctuations The lowest pressure must be selected to guarantee a continuous, adequate supply of water The lowest pressure in the public main usu- ally occurs in the summer because of lawn sprinkling and supplying water for au -conditioning cooling tow- ers Future demands placed on the public main as a result of large growth or expansion should be consid- ered 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 E103 3(3) When estimat- mg peak demand sizing methods typically use water supply fixture units (w s f u ) [see Table E103 3(2)] Tlus 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 21 Estimate continuous supply demand in gallons per minute (L/m) for items such as lawn sprm- klers and air conditioners, and add the sum to the total demand for fixtures The result is the estimated supply demand for the building sup- ply 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 31 Pressure required at the fixture to produce required flow See Sections 604 3 and 604 5 32 Static pressure loss or gam (because of head) is computed at 0 433 psi per foot (9 8 kPa/m) of elevation change 33 Loss through a water meter The friction or pressure loss can be obtained from the manufac- turer 34 Loss through taps in water main [see Table E103 3(4)] 35 Losses through special devices such as filters, softeners, backflow prevention devices and pressure regulators These values must be obtained from the manufacturers 36 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 37 Loss caused by pipe friction can be calculated where 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 pip- ing 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 140 2018 INTERNAT10NAL PLUMBING CODE® 11 1 UER CopyngbtOo2.017 ICC ALL RIGHTS RESERVED A—LDd by H®Ih¢ Van DmA(Rvdme Oo,dA od om),(Qty of ERmdNmod)O[do,N=b,,*1008170DI 01 JM 15, ZMO oc ss AM (PET) mt to S I ( 1, sAg,e^ '^Rt, ICC No otths TAodomoo. m At6sodomo- by any Ot Party o[ AAmboemd,Oo[vsd Mgle —ooly o,and Nyodwg GMIRISAd ANY VNAVTHO OLDER REPROD ,,MN OR D ISIRIEVTION IS VIOLATION OP THE FED REAL COPYRIGHT 11 AND THE LICENSE AGREEMENT, AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER APPENDIX E 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 that includes the corre- sponding water supply fixture unit and conver- sion to gallons per minute (L/m) flow rate to be expected through each section Sizing methods require the determination of the "most hydrauli- cally remote" fixture to compute the pressure loss caused by pipe and fittings The hydrauli- cally remote fixture represents the most down- stream 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, eleva- tion and the residual pressure required by Table 6043 The two most common and frequent complaints about the water supply system oper- ation 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-mch (51 mm) corporation cock at which point the minimum pressure is 55 psi (379 2 kPa) In the building base- ment, 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 E103 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 El03 3(1) should first be constructed The steps to be fol- lowed 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 break- ing at major changes in elevation or where branches lead to fixture groups After point B [see Figure E103 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 lme-by-line recommended tabular arrangement for use in solving pipe sizing The objective in designing the water supply system is to ensure an adequate water supply and pressure to all fix- tures and equipment Column 2 provides the pounds per square inch (psi) to be considered separately from the min- imum pressure available at the main Losses to take into consideration are the following the differences in eleva- tion 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 back - flow 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 E103 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 fix- ture 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 sys- tems, add the gallon -per -minute demand to the intermit- tent 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 pres- sures at different times of day and year The available pressure can be checked from nearby bwldmgs 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 dis- placement type, compound type and turbine type The maximum pressure loss of such devices takes into consid- eration the meter size, safe operating capacity (gpm) and maximum rates for continuous operations (gpm) Typi- cally, equipment imparts greater pressure losses than pip- ing Line D: Select from Table E103 3(4) and enter the pres- sure 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 INTERNAT10NAL PLUMBING CODE® 141 I 1 1 1 CALFIEIL @ 2017 ICC ALL RIGHTS RESERVED Awned by H®Ih¢ Van Dme(Rv dme Oo,dv od om).(Dtyof PnmdNmod)O,do,N=b¢*1008170DI 01 JM 15.

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 mea- sured to determine the developed length However, in sys- tems 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 far- ther from the main source of supply The following for- mula is an acceptable method to determine trial pipe 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 per- centage 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 gpm = 2'/ inches To deter- mine the equivalent length of run to the most remote out- let, 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 It x 15 = 338 ft) The total equivalent length of run for determining a trial pipe size is 338 feet Example: 936 (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) Step 7 Column 6: Select from Table E103 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 devel- oped length plus the equivalent lengths of pipe corre- 142 2018 INTERNAT10NAL PLUMBING CODE® CopyngbtOo2.017 ICC ALL RIGHTS RESERVED A—LDd by H®Ih¢ Van DmA(Raodme Oo,dA od om),(Qty of FRmdNmod)O[do,N=b,,*1008170DI 01 JM 15, ZMO oc ss AM (PET) Mt,mmt to Fk ff., I (firill RR 1, s Ag,e^ '^Rt, ICC No o tths TAodomoo. m At y goodomo- by any Ot Party o[ AAmboemd,Oo[vsd Mgle —ooly oTymg and Nyodwg GMIRISAd ANY VNAVTHO OLDER REPROD ,,MN OR D ISIRIEVTION IS VIOLATION OP THE FEDERAL COPYRIGHT 11 AND THE LICENSE AGREEMENT, AND REJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER APPENDIX E TABLE E.1 PRESSURE LOSS PRESSURE LOSS COLD WATER FITTINGSfVALVES EXPRESSED AS HOTWATER FITTINGS/ EXPRESSED AS PIPE SECTION EQUIVALENT LENGTH PIPE SECTION VALVES EQUIVALENT OF TUBE OF TUBE (feet) (feet) 3-2'/L" Gate valves 3 A-B 3-2'/," Gate valves 3 A-B 1-2'/z' Side branch tee 12 1-2'/L" Side branch tee 12 1-2'/," Straight run tee 05 B-C 1-2" Straight ran tee 7 B-C 1-2" 90-degree ell 05 C-F 1-2'/," Side branch tee 12 C-F 1-1'/L" Side branch tee 7 C-D 1-2'/L" 90-degree ell 7 C-D 1-'/," 90-degree ell 4 D-E 1-2'/," Side branch tee 12 D-E 1-1'/L" Side branch tee 7 For SI 1 foot= 304 8 min, l inch = 25 4 mm sponding 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 esti- mate for this example is found in Table E 1 Step 8 Column 7: Add the figures from Column 4 and Column 6, and enter in Column 7 Express the sum in hundreds of feet Step 9 Column 8: Select from Figure E103 3(3) the friction loss per 100 feet (30 480 mm) of pipe for the gallon -per -min -
