New replacement shower arm is leaking
The shower arm on my shower broke and I had to replace the shower arm and flange. I put pipe thread seal tape on the end of the new pipe before putting it in. I tighten the arm on the pipe and turned on the water to check for leaks. It still leaks. I tried to tighten it more but ended up breaking the new shower arm. I got a new shower arm and tried again. It still leaks, I tighten it again but I'm afraid to tighten it too much or it will break again. What else can I do to stop the new shower arm from leaking?
Thanks,
Gina
