Does my household plumbing contain lead?
The 1986 Safe Drinking Water Act Lead Ban required the use of “lead-free” pipe, solder, and flux in the installation or repair of any public water system or any plumbing in a residential or non-residential facility providing water for human consumption. If your house was built prior to 1986 your plumbing could have lead in it. There is also potential for your plumbing fixtures such as faucets to contain lead. The US issued a final rule on September 1, 2020, requiring all manufacturers or importers certify that their products, now including fixtures such as faucets, be “lead-free” within 3 years.
