IAPMO concludes technical committee meeting for 2023 WE•Stand

The International Association of Plumbing and Mechanical Officials (IAPMO^®) concluded its technical committee meeting toward the development of the 2023 edition of its Water Efficiency and Sanitation Standard (WE•Stand).

With previous editions being an American National Standard, WE•Stand focuses on achieving safe and efficient water use in both residential and non-residential buildings.

The technical committee, consisting of a broad coalition of industry experts — installers, inspection officials, contractors, engineers, and manufacturers — considered public comments to amend the WE•Stand in advance of the release of the 2023 edition. The actions to accept, modify, or reject these comments were electronically balloted to the technical committee for formal voting between June 5-26. The results of the votes will be made public in the Report on Comments to be published for review in September.

 The WE•Stand technical committee met and considered public comments seeking to amend the code in such areas as:

• temporary connections to plumbing equipment for testing;
• general requirements for plumbing and mechanical systems;
• maximum flow rates for fixture fittings;
• reverse osmosis water treatment systems;
• water consumption rates for combination ovens;
• steam sterilizers used in medical and laboratory facilities;
• leak detection and control devices;
• backflow protection;
• the Water Demand Calculator (WDC);
• gradient of horizontal urine diversion piping;
• maximum hot water system ratios;
• disinfection devices;
• onsite wastewater treatment systems for direct potable water reuse;
• and water efficiency rating systems.
