    Deadline to Submit Proposed Changes to 2024 National Standard Plumbing Code (NSPC) is March 1

    In order to facilitate the development of an updated National Standard Plumbing Code — Illustrated™ (NSPC), the IAPMO NSPC Committee requests proposed changes to the 2021 NSPC. All proposals are due by March 1, 2022. 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, please visit www.iapmo.org/nspc.

    All proposed changes must be submitted in electronic form to nspc@iapmo.org. 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. EST deadline March 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.”

    For more information, please contact the IAPMO NSPC staff at nspc@iapmo.org.
