Milwaukee Valve Co. has manufactured drinking water valves for many decades. In association with requirements for our industry and products, we’ve been closely following the rapidly changing legal landscape in this area. In 2003, Milwaukee Valve became the first U.S. valve company to offer a bronze valve that met the requirements of NSF 61. Later that same year, multiple lines of brass plumbing valves also meeting this standard were introduced.
More recently, the California requirements for limitation of lead in valves to less than .25% on a total weight basis have been driving the industry and the rest of the regulatory landscape, so that most valve makers are rushing now to produce valves that meet the much-tighter limit.
