IAPMO released the 2021 edition of the National Standard Plumbing Code – Illustrated (NSPC). An updated version of the 2018 NSPC, the book may be purchased via the IAPMO web store at http://bit.ly/2vvHDfV.
The 2021 NSPC provides the latest information about common materials, fixtures, devices and equipment systems used or installed in plumbing systems. This new edition is printed in the popular illustrated format, with comments and illustrations clearly shown as supplemental information. The illustrations and supplementary notes make it an indispensable training tool.
Appendix G, intended to promote safe and efficient water use in both residential and non-residential buildings, has been updated with revised excerpts from the 2017 Water Efficiency and Sanitation Standard (WE•Stand). Also new in the 2021 edition is Appendix L: Tiny Houses, which was added to address safe and reliable plumbing system requirements for both permanent single tiny houses (Part I) and for tiny house communities (Part II).
“In keeping with the NSPC’s long history of establishing safety requirements for both water supply and sanitation systems, the NSPC Committee has kept the 2021 NSPC up to date with the latest changes in the plumbing industry regarding new products, installation procedures, and public health and safety,” said Frank Maddalon, NSPC Code Committee chairman.
First published in 1933, the NSPC is designed to ensure the proper installation of plumbing systems, providing local and state governments, code administration bodies, and the industry with a modern code to protect health and promote safety. In 2017, IAPMO and the Plumbing-Heating-Cooling Contractors — National Association (PHCC) executed an agreement transferring ownership of the NSPC to IAPMO.
