Pride Plumbing came out to replace a section of galvanized pipe inside a bathroom wall. We cut an access hole in the bathroom wall, cut the galvanized pipe out, ran new PEX pipe down to the CPVC pipe that the galvanized pipe had previously been connected to, and connected onto it using PEX fittings. We turned the water on and checked for leaks and there weren't any. We then tested the toilet, and it filled very slowly. So, we tested the toilet tank's braided stainless-steel water supply line in a small bucket, and it had ample pressure. We notified the customer that from all the work that had been done, debris had clogged the toilet tank's water fill valve, and it needed to be replaced. He stated that he would do it himself. Finally, we installed a plastic plumbing access panel to cover the hole we cut in the wall.
