my shower head broke behind the wall. I can see a connection just behind the wall, but I don't know how to get to it without cutting through the wall. If I do have to cut the wall, what is my best way of doing this and what would be the easiest way to take out the broken pipe from the wall? I am a widow and my husband did all these things, with me watching, so I know what has to be done, I just don't know how to start.
