I'm working on a bathroom remodel and will be installing a Kohler shower valve with output to 2 way transfer value with 2 outputs: 1 to shower head and 1 to hand help sprayer. Both of these will use a standard brass drop elbow. I'm OK on the shower head - the angled shower arm with male threads will extend into the finished wall and screw into that elbow. So the shower head elbow will have a temporary 6" nipple with cap installed for testing, and that test nipple/cap can be easily removed after the finished wall is in place, with enough pipe exposed to attach a pipe wrench.
My question is related to the connection for the hand help sprayer. That uses a small finished elbow (with the nice factory finish) that does not extend into the wall to the drop elbow, and will need a properly size nipple installed in that drop elbow. So if I understand correctly, about 1/2" of that nipple should extend past the finished wall for the connection of that finished elbow for the hand held sprayer hose. That exposed 1/2" of the nipple is all thread, so how do you tighten that nipple down without tearing up the threads, after the finished wall is in? My assumption is, that instead of installing another temporary 6" nipple & cap here, I should attach the properly sized permanent nipple before the finished wall goes in, then cap it for pressure test, and not try to install it after the finished wall is in place. How do you pros usually handle this?
