brass nipple lengths
On a current tile job I stalled a separate drop elbow for a handheld shower. The fixture requires a properly-sized 1/2" threaded nipple for the base to rest snugly against the tile wall. As it happens, the tile was floated out a bit, so a 3" nipple is too short, but a 3 1/2" will probably be too long. Is there a simple solution to this before I open it from the wall behind it to make an adjustment to the elbow? Thanks much.
