Ontario, Calif. — The International Association of Plumbing and Mechanical Officials (IAPMO®) concluded technical committee meetings toward the American National Standards Institute (ANSI)-accredited development of the 2024 editions of the Uniform Solar, Hydronics and Geothermal Code (USHGC®) and Uniform Swimming Pool, Spa and Hot Tub Code (USPSHTC®).
The technical committees, consisting of a broad coalition of industry experts — installers, inspection officials, contractors, engineers, and manufacturers — considered public comments to amend the USHGC and USPSHTC in advance of the release of the 2024 editions. Their actions to accept, modify, or reject these comments were electronically balloted to the technical committees for formal voting between June 5-26. The results of these votes will be made public in the Report on Comments to be published for review in September.
The USHGC technical committee met and considered public comments seeking to amend the code in such areas as: hangers and supports for piping and tubing; disposal of hydronic fluid; freeze protection; comingling of hydronic system fluid and potable water; expansion tanks; engineered fluid expansion storage systems; oxygen diffusion corrosion; vented closed-loop systems; non-oxygen barrier closed-loop systems; joints between different materials; automatic makeup fluid; drainback systems; combustibles within ducts or plenums; site surveys; shutoff valves for equipment and appliances; ground heat-exchanger installation practices; vertical and horizontal setbacks for ground-heat exchangers; tracer and warning markings for buried piping; simplified schematics for closed-loop and open-loop geothermal energy systems; ambient temperature loops and distributed energy systems; and net zero and net positive buildings.
The USHGC is a model code developed by IAPMO to govern the installation and inspection of solar energy systems as a means of promoting the public’s health, safety, and welfare.
The USPSHTC technical committee met and considered public comments seeking to amend the code in such areas as: construction site fencing; slip-resistant walkway surfaces; artificial and underwater lighting levels; zero-depth entries; pool wall slopes; float lines; finishes and surfaces; handholds; walkways; deck drainage; turnover time; water chemistry; oxidation reduction potential; ozone removal; surge tank storage capacity; and elevated pools, spas, and aquatic venues.
The USPSHTC is a model code developed by IAPMO to govern the installation and inspection of both public and private swimming pools, spas, and hot tubs to ensure the safety of their operation.

IAPMO® has released Peak Water Demand Study: Full Study, a comprehensive analysis redefining water supply system sizing for residential and multi-family buildings. Based on real-world data from more than 1,000 households, the full study provides an evidence-based approach to right-sizing plumbing systems — demonstrating reductions in water waste, construction costs, and public health risks.
ASSE/IAPMO/ANSI Series 6000-2024, the Professional Qualifications Standard for Medical Gas Systems Personnel, has been designated as an American National Standard by the American National Standards Institute (ANSI) and is now available for purchase. This new edition of the ASSE Series 6000 builds on the 2021 version and includes key updates, including the addition of Standard 6070 for Medical Gas Systems Design Instructors.
New Jersey has officially declared March as March4Water Month, recognizing the importance of strong water infrastructure, while California has introduced legislation to follow suit. These actions highlight the growing recognition of the need for policies that strengthen plumbing systems and safeguard access to clean, reliable water in the face of natural disasters and other infrastructure challenges.
