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

    I would recommend you to talk with a hot plumber in your area, as they might tell you what’s causing the build-up.

    Probably not helpful to you, but if someone has an issue with lime build-up:

    but I live in a limestone-heavy place (also known as HARD water 🎸😎) and pipes are more choked than my heart arteries. That said, I tried many stuff (cleaning vinegar, cleaning vinegar + baking powder, specific products, etc.) and from all of them the best has been citric acid: There is a huge difference in quality between products, (not represented by price!) but by concentration, get the cleaning type not the food type.

    What I do:

    • Turn off the main and drain the lines. (Turn off all filtration stuff)
    • Get a five-gallon mix in a bucket with warm or hot-ish water.
    • Use a high-point access to let the solution in.
    • Let it do its thing for a morning (e.g. 6 hours maybe but 4h also will do the trick).
    • And then flush it, flush it GOOD.

    For the hard stuff, there’s sulfamic acid, but so far I never needed it, and it is not so good for PVC or PEX. If someone is desperate and using PVC, muriatic acid can do wonders (and a lot of damage).
