Sorry for the delay, thanks. I have managed to un glue that collar but cannot get it off the pipe, if we turn it, it stays same place and it try and pull it off it feels like pulling the pipe with it
I removed my current shower arm which has 4 screws securing it to the wall. This pipe is 120mm with no thread it just pushed into the current arm. I wish to replace the arm but cannot find anything that fits. Is the pipe shown in the picture meant to unscrew?
