PREFACE
Introduction
The International Plumbing Code® ( I PC®) 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 2021 edition is fully compati
ble with all of the International Codes® (I-Codes®) published by the International Code Council® (ICC®),
including the International Building Code®, International Energy Conservation Code®, International
Existing Building Code®, International Fire Code®, International Fuel Gas Code®, International Green
Construction Code®, International Mechanical Code®, International Private Sewage Disposal Code®,
International Property Maintenance Code®, International Residential Code®, International Swimming
Pool and Spa Code®, International Wildland-Urban Interface Code®, International Zoning Code® and
International Code Council Performance Code®.
The I-Codes, including this International Plumbing Code, are used in a variety of ways in both the
public and private sectors. Most industry professionals are familiar with the I-Codes as the basis of
laws and regulations in communities across the US 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 set
tings, including:
•
•
•
Voluntary compliance programs such as those promoting sustainability, energy efficiency and
disaster resistance.
The insurance industry, to estimate and manage risk, and as a tool in underwriting and rate
decisions.
Certification and credentialing of individuals involved in the fields of building design, construction and safety.
•
Certification of building and construction-related products.
•
US 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.
Development
This 2021 edition presents the code as originally issued, with changes reflected in the 2003 through
2018 editions and with further changes approved by the ICC Code Development Process through 2019.
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 adequatel
