I have a palm harbour mobile home. The shower arm itself needs replaced. But after I remove the flange and shower head. The arm itself will turn in circles. Its almost like there's a swivel om the arm and it keeps turning and won't come loose. Any ideas on how to remove this type of shower arm?

Unusual, show us a picture.

I will take one tonight thanks

Duh

OK here's pics

The whole deal and the inside turns in circles but won't loosen.

Speedball1 used to be a plumber for mobile home companies, he will likely come along with a fix

I am going to have to fix mine too. I found out it has a nut and a large washer on the inside of the wall and the trim ring on the front side tightens up against it. I will probably have to cut out a small hole on the opposite wall to remove the nut and washer and install the new shower arm
