Submission Deadline Extended to April 1 for Proposed Changes to the 2024 NSPC

The National Standard Plumbing Code (NSPC) Committee has extended the deadline to submit proposed changes to the 2024 NSPC to April 1. Proposals accepted by the technical committee will appear in the 2024 NSPC.

The NSPC uses an annual review process and publishes the complete code every three years. For a copy of the code change form with instructions, or more information on the NSPC, visit

All proposed changes must be submitted in electronic form to [email protected]. If a standard is referenced, a copy of that standard must accompany the proposed code change that is submitted to the committee.

No proposals will be accepted after the 5 p.m. EDT deadline on April 1, 2022.

IAPMO urges its members and other interested parties to get involved in the code development process. Designed to ensure the proper installation of plumbing systems, the NSPC provides local and state governments, code administrative bodies, and the industry with a modern code to protect public health, safety, and welfare.

“The NSPC is developed by all segments involved in the p-h-c industry: contractors, inspectors, manufacturers, engineers, and labor,” said NSPC Chairman Frank Maddalon. “The NSPC has played a vital role as the state code for New Jersey and the testing code authority for master plumbers and inspectors since 1977.”
