Hey guys and Gals. If someone can give me some guidence, it would take a huge weight off my shoulders.
Essentially my pipes are banging in a two story condo, whenever any fixture is turned off. Found out from the previous owner. That up until 10 years ago the condo had PB pipe. When it ruptured all the pipes in the condo were changed to copper. Apparently the pipes have been banging for ten years. (yeesh) So this is where I’m at. Pipes bang at the same place when any fixture is turned off (but given it is a two story condo. I cant narrow the exact location down since its somewhere near the stairwell. So instead of tearing the walls apart, I installed an air chamber @ the hot water heater. Well, this worked for about two days and then the banging returned. (Figured it just flooded) I Checked the pressure and it is @ 60 psi. (which seems normal) If I decrease it to 40 or so psi by closing the ball valve the banging will go away. I guess my question is. Since the pressure seems normal. Is it probably just a loose/unstrapped pipe? And even if that is the case, since a simple air chamber made it go away for a couple of days. Would taking it out and replacing it with either an arrestor or expansion tank be the way to go?
Any ideas would be greatly appreciated. Since, short of tearing the walls down, I really don’t know which way to go.
