I have a shower head that has been installed at about chest height. It's not been worth it to tear apart and re-build the tile wall to move it to a more sensible height, so instead I've installed a hand-held shower head and bracket. This part works fine. The old shower-head tube still sticks out at chest height though, with the hose from the hand shower sticking out past that. I don't like the way the tube sticks out and so I've bought a wall union to replace it, similar to this Grohe unit.
Now my questions:
How do I work out the length of nipple I need between the fitting inside the wall and the union? Will I be able to get the wall union to fit flush against the tile wall?
If I work out I need a certain length of nipple, will I be able to buy that or have it made up?
How do I tighten the parts together? Should I tighten the nipple first, then the union on top? Or do I tighten the two parts together by turning the union?
Is there any good strategy for preventing leaks inside the wall from the inside thread joint? Just use a bunch of pipe dope and hope for the best? It is a shower head and so doesn't carry the same pressure as a regular line and is only pressurised when the shower is running.
