We live in an older house in the US. We got a note in the mail from the city that pipe from the main to the house might be lead. They looked at building plans/ permits. The length is (15ft) so the impact is minimal if it’s actually lead. The piping inside is copper and pvc for drains. But we had the water tested anyway. Lead isn’t good for you.
