Hi friends, I'm looking for some advice on installing a Moen shower valve (model #82355). This valve has threaded female inlets for the hot/cold lines and the same for the tub/shower outlets. I am using brass/cpvc male thread adaptors.
Here's the problem: I installed the valve using teflon tape at all connectors and ran a pressure test. After a few minutes a bead of water appeared on the exposed threads of the hot inlet. Everywhere else was bone dry. So, I disconnected the hot, removed the tape, and used teflon joint thread compound (oatey). No go - more water this time. Ok, it must be the fitting. I get another fitting and try it with tape. Same leak. Try it with joint compound. Same leak.
Ok, it must be the valve. So, I call Moen and to their great credit I had another valve in my hands the next day. Install with new fitting (+tape). Guess what? Another leak. Same place - hot inlet. All the other fittings hold perfectly well on both valves, so I sincerely doubt it is my technique. Plus, I've now tried three different fittings, so I doubt that is the problem.
I called Moen back this morning and the only advice I got so far was to buy my fittings from a different store. Ummm... but the cold side doesn't leak. A product specialist is going to call back this afternoon. I can't see what they can do besides send another valve or refund my purchase price. We like the trim on this one, though (it is a matching set with the sink faucet), so I'd rather not go shopping for a new brand. The funny thing is that I specifically chose Moen for its reputation for quality.
If anyone has a suggestion on how I can make this valve work I'd love to hear it. Or perhaps there is a high quality universal valve out there?
Thanks
Bill
