I had an issue with my pipes rattling and to say the least it was driving me crazy. I have called at least 6 or 7 plumbers over the course of this year to try to fix the problem. Some had no clue and some told me that we had to cut open walls to locate a loose pipe to secure it. I probably would have done it too if I had any trust in the plumbers who gave me that advice. I called Priority plumbing and their plumber Tony took some time to investigate the issue. He determined that it mostly happens when the toilets flush so instead of ripping open the walls, he replaced the components in the tank with parts that dont open and close rapidly. Turns out the home depot chepo brand was the cause of this whole mess. Lesson learned, call a reputable professional company when it comes to Plumbing, Electrical or any other professional trade. You definately get what you pay for.
