Plumbing Manufacturers International (PMI) represents its members’ interests when providing technical input into the development of codes and standards, as well as when using its technical expertise to advocate for sound environmental and public health policies. Working with PMI members represented on its Technical Committee, PMI participates in federal, state and local regulatory and legislative processes and supports the plumbing manufacturing industry’s growth and expansion.

Throughout the year, PMI members strategize and conduct technical information exchange sessions via frequent Tech Talk conference calls and at the annual PMI Manufacturing Success Conference.

PMI efforts have led to codes and standards harmonization and uniformity within North America, enabling manufacturers to make one-type-fits-all products that benefit consumers. PMI’s Product Category Rule (PCR) Guidance Documents help program operators apply consistent rules and calculations when developing PCRs for products.

PMI’s staff and members play leading roles as contributors to key industry bodies, thereby ensuring a practical, common-sense approach to the development of codes and standards. PMI members or staff have participated in committees organized by the Alliance for Water Efficiency (AWE), American National Standards Institute (ANSI), American Society of Heating Refrigerating and Air-Conditioning Engineers (ASHRAE), American Society of Mechanical Engineers (ASME), American Society for Testing and Materials (ASTM), CSA Group, International Association of Plumbing and Mechanical Officials (IAPMO), International Code Council (ICC), NSF International, Plumbing-Heating-Cooling Contractors Association (PHCC), and other organizations.
