I think the idea was that water pipes will build up a later of calcium anyway, so they aren't harmful.

In Germany there are probably tons of lead pipes still in existence and and only from 2026 is there a law that they all _have_ to replaced (previously they could stay as long as the water lead content was in the permitted range, but I don't think anybody ever checked).

Right... Maybe in that 20% of the world that has mostly calcium rocks.

Water tends to slowly eat away calcium, not the other way around.
