I replaced my water installation some weeks ago. The copper pipes did not show build-up. I cut the pipe at the hydrofor to make it easier getting it up the stairs that was another story. I think it’s 45 years of build-up

    This build up can be the only thing keeping you from drinking lead too. I believe damage to the buildup due to a reduction in water additives was what happened in flint.
