How much lead can a faucet or plumbing device contain?
Under the 1996 amendments to the Safe Drinking Water Act (SDWA), no plumbing product used in the installation or repair of any plumbing providing water for human consumption can contain more than 8.0 percent lead. The amount of lead contained in the plumbing product is usually governed by its manufacturing process. In order to find out how much lead is contained in a plumbing product, one should contact the manufacturer or the importer/distributor. Another approach is to send the plumbing product to a laboratory and have it analyzed for lead content. However this approach may not be practical, since the cost of the test could be several times of the purchase price of the product.
