Dear friends, once again this novice DIY'er must fall on the mercy of the experts!
I'm building a shower and will install the mixer and arm inside a stud wall, with hardiebacker 12mm and tiles on the side facing into the shower cubicle. All is going well so far in that I have the wall built, the mixer valve installed and everything connected up. I cannot, however, figure out how I'm meant to install the shower arm (pictures below).
I think that a so-called "drop ear elbow" is the correct thing to use. It will accept the male 1/2" thread on the arm and I can screw it down nicely to a noggin. Two problems I have, though, the first being that when I screw my arm into my backplate, it doesn't all align nicely and the plate ends up at about a 35 degree angle relative to the square arm. I'm assuming that a tight fitting here is essential in order to prevent leakage, as well as to support the arm. What to do? Should I cut or file a bit of the thread off in order to get these two things to marry up correctly?
Problem the second (or rather question) is to how figure out exactly where to mount the elbow. Getting exactly the right depth here is crucial, of course, but I'm quite unclear as to how to go about doing it. Should I make a "mock up" of the board/tile, drill a hole through it and then use that to correctly position the arm? Then screw the elbow on to figure out the correct position? What then?
As you can see, I'm a little lost here so any advice much appreciated!
