The International Association of Plumbing and Mechanical Officials (IAPMO) published the 2021 Uniform Plumbing Code (UPC) in the first quarter of 2020.
As anticipated, the 2021 edition of the UPC has some significant modifications to the sections covering drinking water treatment products. As the 2021 revision of the UPC becomes adopted by states and local jurisdictions, it’s important for industry manufacturers and dealers to understand the code changes that affect drinking water treatment product installations.
