I installed a 12" ceiling mount shower arm but having problems with it leaking.
Its a standard 1/2 IPS connection but on one end the threads are tapered and is about 2". The reason for the length is the escutcheon is supposed to screw on all the way to the end of the thread area so no threads are exposed, then a nut.
So if I screw this on to my connection a good majority of the threads arent used since its tapered. I thought it was bottoming out so I cut off a good inch of tapered thread but it still leaks. I am using teflon tape and a little pipe dope over the threads.
Where am I going wrong on this?
Also, I had to use brass fittings to extend the length from my drop elbow. The reason, I extended the copper line over the 2x4 rafter and soldered a standard drop elbow. This extension over the ceiling is supported by hardwood which is screwed into 2 rafters. In order to have a straight pipe coming out of the ceiling I had to add approx. 2.5" threaded brass fitting and a coupler to gain this length to be right abouve the sheetrock. I did this to get the most of the 12 arm out of the ceiling. However, I gained potential problems of 3 additional areas to leak. The only leak I am mentioning is at the 12" shower arm and not the fittings.
