If the pipe is silvery gray and: 1) is easily scratched, 2) the metal seems soft, and 3) a magnet doesn’t stick to it, you likely have a lead pipe.
If you have a lead service line, it should be replaced. Please contact us first to ensure the utility-owned portion is inspected and replaced (if needed) at the same time. Partial service line replacement can actually increase the amount of lead released into your water. Until then, you should follow the previous recommendations to reduce your exposure to lead. You should also consider water filters for drinking and cooking, especially if high risk individuals live in the home.
