The International Association of Plumbing and Mechanical Officials

Founded in 1926, the International Association of Plumbing and Mechanical Officials (IAPMO®) has been protecting the public’s health and safety for over 90 years by working in concert with government and industry to implement comprehensive plumbing and mechanical systems around the world.

The IAPMO code development process ensures openness and transparency for the development of consensus-based codes for use in the built environment. Our codes are unique, as they remain the only codes developed exclusively for plumbing and mechanical applications that employ an ANSI-accredited development process, providing a voice and a vote to all industry stakeholders.

IAPMO provides leadership toward addressing the global need for sound water efficiency-based codes and standards while working to avoid unintended consequences that have the potential to compromise health and safety. IAPMO supports science-based research and policy-based initiatives at all levels of government, with the goal of helping provide for the safe use of water in buildings around the world.

Alongside North America, IAPMO has assisted with code development in Saudi Arabia, China, India, Jordan, Egypt, Israel, Vietnam, Indonesia, Philippines, Venezuela, Colombia, and the United Arab Emirates, and, in support of the World Plumbing Council, has also worked with the World Health Organization to help bring sound, efficient plumbing systems to developing nations.

Finally, IAPMO’s foundation – the International Water, Sanitation and Hygiene Foundation (IWSH) – provides an additional platform to engage world-class skilled Champions and Experts for collaborations with government, industry and communities-in-need to encourage sustainable development, action and change for better public health.
