The U.S. Environmental Protection Agency finalized its changes to existing regulations to provide a framework of compliance under the Reduction of Lead in Drinking Water Act of 2011 (RLDWA). The changes codify aspects of RLDWA, which lowered the allowable maximum lead content of plumbing products to further protect the public from lead used in plumbing materials that provide water for human consumption.

The final rule “requires manufacturers with 10 or more employees, and importers entering products purchased from or manufactured by manufacturers with 10 or more employees, to obtain third-party certification by an ANSI-accredited third-party certification body. The requiring of third-party certification will not pose a significant impact on the current products sold since current model plumbing codes adopted by state and local authorities already require that plumbing system products intended for potable water applications comply with NSF/ANSI 372, Drinking Water System Components — Lead Content.”

The plumbing manufacturing industry began transitioning its products to the new lower lead levels circa 2014. Even better, the International Plumbing Code and International Residential Code were amended to reflect the RLDWA lead content requirements in drinking water pipes, pipe fittings, joints, valves, faucets and fixture fittings in the 2015 edition. For several years, ICC Evaluation Service has offered certification service to the requirements of NSF/ANSI 372 and is available to address your certification needs.
