Can "lead-free" plumbing fixtures or devices leach lead?

Yes, as noted in response to Question 2, any plumbing device or fixture that contains lead and is in contact with the water is a potential source of contamination. Brass fittings and plumbing fixtures, containing 8% or less lead, have been found to contribute high lead levels for a considerable period of time after their installation, even in cases where these devices are in contact with relatively non-corrosive waters. The amount of lead that may leach into the water from a brass faucet or fixture is not solely related to the amount of lead contained in the alloy. The amount of lead leaching from a brass alloy is greatly influenced by the manufacturing process. • Is There a Performance Standard Limiting the Leaching of Lead into Drinking Water from Faucets, Fittings, Fixtures, Pipes and Plumbing Devices? A voluntary standard, NSF International's consensus Standard 61, (ANSI/NSF Standard 61: Drinking Water System Components-Health Effects), including inline and endpoint devices has bee ... more
