Stem hole showing
Had plumber install new tub faucet (one piece) in fiberglass tub/shower. Center stem continues to leak behind wall after 3 additional trips back to my house to 'fix'. I discovered small hole coming from the fixture in the center - appears to be the bottom of the stem hole(plumber did not mention this). His staff said it can't be lowered. Wasn't aware this fixture wasn't same height as previous. Any solutions at this point besides buying
2nd new fixture? Plumber caulked it twice already.
Re: Stem hole showing
If you have a hole (small, medium or large) in your fixture, then you have a defective fixture.
If you bought the fixture yourself, go get a 2nd one.
If your plumber provided the fixture, insist that he installs a new one.
