IAPMO’s Water Demand Calculator ® included as a sizing option in Appendix G.
New Appendix M addressing the impact of water temperature on the potential for scalding and Legionella growth.

“The 2024 NSPC reflects the most recent changes in the plumbing industry concerning new products, installation procedures, and public health and safety, consistent with the code’s long tradition of establishing safety requirements for water supply and sanitation systems,” NSPC Committee Chairman Tom Pitcherello said.
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.
