I had to replace my shower head and bought a new one. When I went to install it (screw it onto the shower arm) I realized it was up-turned instead of down-turned - so shower head could not be used (wrong angle completely).
The shower arm is "plastered" into the wall so i don't think i can twist it around. What do I do? try to remove the plaster (or whatever it is)? Break through it? I dont' want to remove tile or make this into a major project if avoidable.
