Hi Everyone, I wasn't sure if I should post this in the shower forum, but since it has to do with rough-ins I posted here.
My issue- I had a plumber run water lines over to a bathroom where we were adding a shower and install a Kohler K-304-K Rite Temp valve. When he put it in, it looked like it was sticking way too far out from the studs, but when I pointed it out he told me I had misinterpreted the instructions, that he had been doing this for years and years- yadda yadda.
Well, I put up the durock, and after reading the installation about a thousand times, looking at videos, etc- I have a big problem. Two, possibly. First, he did install it WAY too far out on the studs. The plastic ring is supposed to sit behind the durock, but it sits a good 1/4" outside of it... on one side. On the other side, it sits outside the durock about a 1/2"! So now, not only is it too far out, but it is twisted about a 1/4" to the left.
Asking him to come and fix it is not an option- It turns out this guy has major temper issues and blew up at me when I apparently asked too many questions. I was asking questions because I knew things were not right! (I won't even get into the other things he ended up messing up that I had to fix).
So, as I see it my options are these:
1. Take down the durock, have a plumber come in and pay yet more $ so that he can move the pipes/valve to where they should be.
2. Take down the durock, shim out the studs 3/4" and re-durock.
3. Have a breakdown. Oh wait, I've already done that.
I am attaching photos of the rough in before drywall, the install manual close up, and the valve as it looks with the durock around it (profile from the side, and then top view so you can see the angle. The dome is not on the valve in those photos). What kills me is the "very tough" plumbing inspector looked at all of his work and passed him. I guess they don't really look at the details when doing an inspection?? Who knows.
At any rate, I appreciate any advice you all can give me.
