Together, the engineers who design products, plumbers who install, test, repair, and inspect systems, officials who enforce regulations, and educators who teach our nation’s plumbers join together to offer their expertise and collectively reach consensus on product and personnel requirements.

Draft product standards and professional qualifications (PQ) standards are developed by working group members. Working groups are typically composed of manufacturer representatives, school representatives, test lab representatives, and outside experts who work in the field. If you have something of value to add, we welcome you to sit on a working group and lend your expertise.
