The International Association of Plumbing and Mechanical Officials (IAPMO) has made significant progress towards the proposed 2027 editions of the Uniform Plumbing Code (UPC) and Uniform Mechanical Code (UMC) during recent Technical Committee Meetings held in Ontario, CA. These meetings, which took place at the Sheraton Grand Hotel in Los Angeles, involved a thorough review and action on 330 public comments aimed at amending the 2024 editions of the Uniform Codes. The UPC Technical Committee addressed various topics such as plumbing fixtures, water supply systems, and fuel gas provisions, while the UMC Technical Committee discussed areas like mechanical ventilation systems, installation of air-source heat pump water heaters, and requirements for hydrogen fuel gas piping. Following compelling discussions, new task groups have been established for the development of the 2030 editions of the codes, focusing on key aspects like heat pump water heaters, grease interceptors, and ecological sanitation systems. The ongoing balloting process of the UPC and UMC technical committees for the proposed 2027 editions will conclude on June 16, with the resulting Report on Comments expected to be released in early August. IAPMO stresses the importance of community engagement in the code development process to ensure that the Uniform Codes effectively uphold public health, safety, and welfare. The organization also encourages interested parties to participate in shaping future standards to maintain a fair and balanced approach.
