IAPMO Seeks Members for Task Group for Hot Water Recirculation Design, Installation, Commissioning, and Operations

Ontario, Calif. — The International Association of Plumbing and Mechanical Officials (IAPMO®) is seeking volunteers to participate on the new Technical Committee for Hot Water Recirculation System Design, Installation, Commissioning, and Operations.

This new manual will develop a holistic approach to the design, construction, commissioning, and operation of domestic hot water systems for the built environment, including but not limited to commercial and multifamily facilities. The goal of this standard will be to develop prescriptive and performance requirements for domestic hot water recirculation systems to minimize energy and water usage while improving safety.  

“This manual will play a crucial role in improving sustainability by reducing water and energy use of hot water systems while also minimizing the risk of waterborne disease and improving the well-being of building occupants,” said IAPMO Vice President of Technical Services and Research Christoph Lohr, P.E.

Founded in 1926, IAPMO seeks to be a worldwide leader in the plumbing and mechanical industry through the protection of health and safety. IAPMO develops industry standards with a focus on plumbing products, solar heating systems and components, mechanical products (including heating, ventilation, cooling, and refrigeration system products) and products used in the recreational vehicle and manufactured housing industries.

“Maintaining the performance of hot water recirculation system is crucial to plumbing resiliency efforts,” said IAPMO Vice President of Codes and Standards Development Hugo Aguilar, P.E. “This manual will complement the work of our standards process and allow for enhanced technical discussions.”

The deadline to apply is Dec. 31. Anyone interested in serving on the new committee may complete the application online HERE

Individuals with questions may contact Christoph Lohr at (909) 731-0219 or christoph.lohr@iapmo.org.


IAPMO develops and publishes the Uniform Plumbing Code®, the most widely recognized code of practice used by the plumbing industry worldwide; Uniform Mechanical Code®; Uniform Swimming Pool, Spa and Hot Tub Code®; and Uniform Solar Energy, Hydronics and Geothermal Code — the only plumbing, mechanical, solar energy and swimming pool codes designated by ANSI as American National Standards — and the Water Efficiency Standard (WE-Stand)™. IAPMO works with government, contractors, labor force, and manufacturers to produce product standards, technical manuals, personnel certification/educational programs and additional resources in order to meet the ever-evolving demands of the industry in protecting public health and safety.
