Hello,
I have just installed an American Standard Shower Set, “Hamptonâ€, model 7221.712. I can not eliminate drip leaks at the point where the water service pipes mate with the “rough-in†valve. The parts in question are called “Ground Joint Inlet†(part # M962341-0070A) on the parts list, but called “Coupling Nut and Union Swivel†on the Installation Instructions. This connection is a mating of a beveled male copper fitting into a beveled bowl shape on the valve. The tightening of the coupling nut is apparently supposed to ‘force fit’ a mate point with the valve.
I have used proper sized wrenches/slip joint pliers to really tighten these two joints, but cannot eliminate a drip leak. The installation is square and plumb, and there are no obvious flaws in either mating surface.
Help! What can I do to fix this? Thanks very much in advance for your expertise.
