Why are lead pipes not used in plumbing anymore?
Water from wells or municipal water systems may contain trace amounts of corrosive elements or compounds that can leach lead from plumbing and dissolve it into the water. Lead is toxic to humans and builds up in the body over time.
What to do if you have lead pipes in your home?
The more the water runs, the less time it has to come into contact with any lead in your plumbing. To flush water from a faucet that might have lead, let the water run for 30 seconds or so.
