The old shower arm has developed a crack and it's weeping water and getting worse. I have to replace it before it damages the wall.
I got it unscrewed easily, but what I found wasn't what I was expecting. From all the descriptions I found on the net and from looking at the replacement arms available in hardware stores, I expected the arm to screw into a fitting behind the wall, sticking out through a hole which can be covered by a flange. Instead, I found this:
A pipe sticking out into the shower. Attached to that is this:
Maybe I have my terminology wrong - which is the "arm", the copper pipe or the chrome cowl? Anyway, I would like to find a replacement for the chrome piece to save myself from hacking open the wall. However, I can't find any similar piece in any physical or on-line store. Can anyone suggest a source for this piece? Any other suggestions on other ways to repair this?
