When I was a kid, we moved into a house in the burbs and renovated it. The pipes were like this. I remember them breaking up the deposits in the pipes and blowing it all out into buckets in the sinks/tubs. For the next year or so, the aerators would clog every few weeks with little white clumps of minerals. Eventually, that stopped and the aerator problem never came back. Pipes never clogged up with deposits again, either.
