I have three shower head arms and when I tighten them down, the arm is pointing at 12:00 instead of 6:00. They are actually falling in different positions. I used the exact same drop ears but I think the threads on the arms are slightly different. Can I cut some threads off the arm and chase back with a threader? The walls are tiled so no access to the drop ear
Thank you

If you wrap enough tape on the shower arm threads, you should be able to get the arm tight enough half a turn earlier.
Do check for leaks after doing this. Cap off the arm with 1/2 in NPT cap, pull back the arm flange, turn on the water and observe.

Yes, you can carefully cut off a little of the thread on the holder (for example, with a file or grinding wheel) and re-cut it with a thread cutter to turn the holder to the desired position. This will allow you to “turn” it to 6:00. Do this gradually, checking the fit so as not to strip the thread.

I have encountered your situation more often than not. Usually teflon tape solves the problem as george described above. But in some cases, if you examine the threads, you can see they are uneven or too shallow on one side. Toss these, they will never seal properly. Here's a link to some replacements from the sponsor here, [www.plumbingsupply.com] (they're a good vendor)
