Hello everyone. Newbie here. Need help. Issue has been going on so long I forgot most of it, but I’ll skip to the ending. Turning fixtures on and the whole house vibrates, I mean violently the copper pipes slamming. Not always and that’s part of the problem. If I turn my water on, or shower, or flush toilet it’s not been doing it lately. But if I turn the bathtub on in the 2nd bath every pipe in house is slamming cold or hot. If I turn on the outside water lines fully open the piping slams, and the spiciest are in a T before the PRV. So here I am now I have the gauge on the cold water laundry line fully open and it reads just above 100#. If I turn the cold water sink line on it drops to 90. If I flush the toilet by itself it drops to 45 if I turn sink & bath on drops to 35. I’ve messed with the PRV but since put it back,I adjusted it cause I put gauge fitting on outside water lines before I noticed they were pipes ahead of the PRV. Anyways I just turned bath on, no noise and dropped to 40, but when I flushed the toilet, the piping is slamming and the gauge is bouncing all over the place 0 to 100 just all over. Help please. Go figure this is one nasty crawl to get to get to the valve. I’m HVAC/R by trade. Thanks
