I have a shower head which is loose and moves back and forth. Fortunately I have access to the back of it and when I looked, the flange on the elbow connector right before it goes into the shower head is just hanging there, simply held by the hole in the drywall! The space to access the pipe is really tight - an air handler is in front of it. I can squeeze to get in there, but can't do anything major. Any suggestions on how to secure this easily?
