Lead-Free Plumbing Law


The Reduction of Lead in Drinking Water Act in the United States went into effect earlier this year, on January 4. The act imposes standards that were already enforced in several states. It defines “lead-free” as less than .25% lead on the wetted surface of pipes, pipe fittings, plumbing fittings, and fixtures used for potable water service. Previous federal laws set the limit at 8%. The new law limits solder and flux to .2%. The act considers any water used for human ingestion — including drinking, teeth brushing, food preparation, and dishwashing — as potable.

Only items used for potable water must to meet lead-free standards. Items frequently exempt from the regulation include toilets, bidets, fire hydrants, shower valves, washing machines, backflow preventers, irrigation equipment, and closed-loop hydronic heating systems used exclusively for non-potable service. Watch our video at the link below for more information. Relevant items that do not meet lead-free requirements should be marked on our website.
