The lead piping in homes in America is the connections/joints between the municipal water hook up at the street, and into the house. That's were the problem lead came from in Flint, MI. I don't think there has been 100% lead piping since, say, the Middle Ages. Even back then, they knew that copper, for instance, had a purifying effect. In modern terms, it's antiseptic.
Frankly, I wonder what the replacement of copper with plastic in all the ticky-tack suburban homes is doing to people.
