Which organization is associated with the Uniform Plumbing Codes?

• A. ANSI
• B. IAPMO
• C. ASHRAE
• D. EPA

Answer: (B)

The key idea is recognizing who creates and maintains model codes for plumbing safety. The Uniform Plumbing Code is published by the International Association of Plumbing and Mechanical Officials, known as IAPMO. This organization specializes in developing uniform codes for plumbing and related systems that many jurisdictions adopt as their local standards. ANSI, while important as an accrediting body that approves standards developers, does not write the plumbing code itself. ASHRAE focuses on HVAC, energy efficiency, and related standards, not the plumbing code. The EPA handles environmental protection and water quality regulations, not code development for plumbing installations. So when you see the Uniform Plumbing Code, the organization responsible for its creation and ongoing stewardship is IAPMO.
