Shower pipes came unanchored
A couple of questions;
1) I think my shower pipes have become unanchored. How do I determine if this is the case before tearing out the wall? When turning on the shower it runs fine and makes no noise for about 3 minutes and then starts banging very loudly. I have seen no evidence of any water leaks. We do have hard water.
2) If I do have to tear out the wall to get to the pipes; how do I remove a cultured marble piece without destroying it in an effort to reuse it? It is one piece about 4 feet wide by 5 feet tall.
