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.

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;

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. For further information on the Code Development Committee responsibilities,
please visit the ICC website at www.iccsafe.org/scoping.

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.

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

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
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.

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.

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 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.

CHAPTER 7
SANITARY DRAINAGE
User note:
About this chapter., Chapter 7 regulates the methods and piping systems that remove water that has served a purpose such as Bushing
water closets, bathing, culinary activities and equipment discharges. The types of materials, drainage faring and the connection methods are
covered for these systems that begin at the receiving fixtures and end at the point of disposal for the liquid waste. A design method for a grav-
ity flow system of vertical and horizontal piping is provided based on the probability of flows from specific fixtures. Vacuum and pumped types
of liquid waste removal methods are also regulated by this chapter.
SECTION 701
GENERAL
701.1 Scope. The provisions of this chapter shall govern the
materials, design, construction and installation of sanitary
drainage systems.
701.2 Connection to sewer required. Sanitary drainage pip-
ing from plumbing fixtures in buildings and sanitary drainage
piping systems from premises shall be connected to a public
sewer. Where a public sewer is not available, the sanitary
drainage piping and systems shall be connected to a private
sewage disposal system in compliance with state or local
requirements. Where state or local requirements do not exist
for private sewage disposal systems, the sanitary drainage
piping and systems shall be connected to an approved private
sewage disposal system that is in accordance with the Inter-
national private Sewage Disposal Code.
Exception: Sanitary drainage piping and systems that con-
vey only the discharge from bathtubs, showers, lavatories,
clothes washers and laundry trays shall not be required to
connect to a public sewer or to a private sewage disposal
system provided that the piping or systems are connected
to a system in accordance with Chapter 13 or 14.
701.3 Separate sewer connection. A building having plumb-
ing fixtures installed and intended for human habitation,
occupancy or use on premises abutting on a street, alley or
easement in which there is a public sewer shall have a sepa-
rate connection with the sewer. Where located on the same
lot, multiple buildings shall not be prohibited from connect-
ing to a common builchng sewer that connects to the public
sewer.
701.4 Sewage treatment. Sewage or other waste from a
plumbing system that is deleterious to surface or subsurface
waters shall not be discharged into the ground or into any
waterway unless it has first been rendered innocuous through
subjection to an approved form of treatment.
701.5 Damage to drainage system or public sewer. Waste
detrimental to the public sewer system or to the functioning
of the sewage -treatment plant shall be treated and disposed of
in accordance with Section 1003 as directed by the code offi-
cial.

1402.2.1.3 Test procedure, other soils. The hole shall
be filled with clear water, and a mmimuin water depth
of 12 inches (305 min) shall be maintained above the
bottom of the hole for a 4-hour period by refilling
whenever necessary or by use of an automatic siphon
Water remaining in the hole after 4 hours shall not be
removed Thereafter, the soil shall be allowed to swell
not less than 16 hours or more than 30 hours Immedi-
ately after the soil swelling period, the measurements
for determining the percolation rate shall be made as
follows any soil sloughed into the hole shall be
removed and the water level shall be adjusted to 6
inches (152 min) above the gravel or coarse sand
Thereupon, from a fixed reference point, the water
level shall be measured at 30-minute intervals for a
period of 4 hours, unless two successive water level
drops do not vary by more than'/1, inch (1 59 min) Not
fewer than three water level drops shall be observed
and recorded The hole shall be filled with clear water
to a point not more than 6 inches (152 min) above the
gravel or coarse sand whenever it becomes nearly
empty Adjustments of the water level shall not be
made during the three measurement periods except to
the limits of the last measured water level drop Where
the first 6 inches (152 min) of water seeps away in less
than 30 minutes, the time interval between measure-
ments shall be 10 in mutes and the test run for 1 hour
The water depth shall not exceed 5 inches (127 min) at
any time during the measurement period The drop that
occurs during the final measurement period shall be
used in calculating the percolation rate
1402.2.1.4 Mechanical test equipment. Mechanical
percolation test equipment shall be of an approved
type
1402.2.2 Permeability evaluation. Soil shall be evaluated
for estimated percolation based on structure and texture in
accordance with accepted soil evaluation practices Bor-
ings shall be made in accordance with Section 1402 2 1 1
for evaluating the soil
1402.3 Subsurface landscape irrigation site location. The
surface grade of all soil absorption systems shall be located at
a point lower than the surface grade of any water well or res-
ervoir on the same or adjoining lot Where this is not possi-
ble, the site shall be located so surface water drainage from
the site is not directed toward a well or reservoir The soil
absorption system shall be located with a ininunurn horizon-
tal distance between various elements as indicated in Table
1402 3 Private sewage disposal systems in compacted areas,
such as parking lots and driveways, are prohibited Surface
water shall be diverted away from any soil absorption site on

INSTALLATION
1403.1 Installation. Absorption systems shall be installed in
accordance with Sections 1403 1 1 through 1403 15 to pro-
vide landscape irrigation without surfacing of water
1403.1.1 Absorption area. The total absorption area
required shall be computed from the estimated daily gray
water discharge and the design -loading rate based on the
percolation rate for the site The required absorption area
equals the estimated gray water discharge divided by the
design -loading rate from Table 1403 1 1
1403.1.2 Seepage trench excavations. 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 excava-
tions 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 side -
wall 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
Smeared or compacted soil surfaces in the sidewalls or
bottom of seepage trench or bed excavations shall be scar-
ified to the depth of smearing or compaction and the loose
material removed Where ram 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

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

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 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

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

APPENDIX E
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 dif-
ference 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 pre-
vention devices, check valves, water softeners, instanta-
neous 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 sys-
tem losses are subtracted from the mimmum water pres-
sure 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 aver-
age pressure loss, as long as the pressure available for fric-
tion 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 pres-
sure 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 fric-
tion losses to the most remote outlet (measured length is
called developed length)
Exception: Where the main is above the highest fix-
ture, the resulting psi must be considered a pressure
gam (static head gam) 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
lnnits, then every run of pipe will 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 dif-
ferences
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
Step 6
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 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-

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 -
me flow in a section (Column 3) and trial pipe size (Col-
umn 5) Maximum friction head loss per 100 feet is
determined on the basis of total pressure available for fric-
tion 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 mdi-
cates 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 fric-
tion 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 deter-
mined 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 differ-
ence 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 opera-
tions using Columns 5, 6, 8 and 9 should again be
repeated
TABLE E.2
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 pro-
cess should be repeated to obtain an economically
designed system
Answer: The final figures entered in Column 5 become
the design pipe size for the respective sections Repeating
this operation a second time using the same sketch but
considering the demand for hot water, it is possible to size
the hot water distribution piping This has been worked up
as a part of the overall problem in the tabular arrangement
used for sizing the service and water distribution piping
Note that consideration must be given to the pressure
losses from the street main to the water heater (Section A-
B) in determining the hot water pipe sizes

APPENDIX E
SECTION E201
SELECTION OF PIPE SIZE
E201.1 Size of water service mains, branch mains and ris-
ers. The minimum size water service pipe shall be '/q inch
(191 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 prac-
tice 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 E103 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
21 Determme the difference in elevation between
the source of supply and the highest water sup-
ply outlet Where the highest water supply out-
let is located above the source of supply, deduct
0 5 psi (3 4 kPa) for each foot (0 3 m) of differ-
ence in elevation Where the highest water sup-
ply 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
22 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 pres-
sure downstream of the pressure -reducing
valve, whichever is smaller
23 Deduct all pressure losses due to special equip-
ment 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
24 Deduct the pressure in excess of 8 psi (55 kPa)
due to installation of the special plumbing fix-
ture, such as temperature controlled shower and
flushometer tank water closet Using the result-
ing minunurn available pressure, find the corre-
sponding 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 devel-
oped length
To determme the size of water service pipe, meter and
main distribution pipe to the building using the appro-
priate 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 E103 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
To determme 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 sup-
ply 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 The size of any branch
or main does not need to be larger than the size of the
main distribution pipe to the building established in
Step 4
SECTION E202
DETERMINATION OF PIPE VOLUMES
E202.1 Determining volume of piping systems. Where
required for engineering design purposes, Table E202 1 shall
be used to determme the approximate internal volume of
water distribution piping
