Very Small leak at Shower Valve on Cold Water Side, Threaded. Tighten it more or ?
I just installed a new Moen shower valve. It takes threaded fittings. I used pex for my hot and cold supply and copper (sweated) for my tub spout and riser. Since the Moens I looked at only came with a shower valve that would take a threaded fitting that is what I went with. The problem I am having is as follows: I bought (2) 1/2 threaded to pex brass fittings. I teflon taped them and installed them on the valve. After everything was connected I turned on the water and I had a small leak on both of the Pex fittings on the threaded valve side not the pex clamp side. I turned off the water and tightened them some more. The hot side is now leak free however the cold side leaks a very small amount. I tightened the crap out of it but can still tighten it some more. However I don't want to over tighten it but I want to stop the leak. What would you guys do? Would you tighten it some more or take it back apart and retry it? My copper sweat joints with the threaded 1/2 pipe thread all work great with no leaks. Any info would be appreciated. Thanks.
