The 2021 NSPC Illustrated edition – an updated version of the 2018 National Standard Plumbing Code Illustrated – is now available at the IAPMO Online Store. This code book provides the latest information about common materials, fixtures, devices and equipment systems used or installed in plumbing systems. The illustrations and supplementary notes make it an indispensable training tool. 

In this new edition, 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 (WESStand). 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).

This new edition is printed in the popular Illustrated format with comments and illustrations clearly shown as supplemental information.
