When taking a shower in one of my bathrooms the pipes make a horrible noise and vibrates when turning on the shower and using hot water. At first it only happened when you lowered the water temperature but now it happens even with the water all the way on hot. I have removed everything I can to check it but can't get to anything. Everything is in the wall. I really don't want to remove the entire tub. Please help!

Did this just happened?

Is any plumbing work done in the house?

Thanks,
John

Started about a week ago. We haven't had any work done. The shower in the other bathroom was backing up so I use liquid plumber to clear it up but that's the only thing that has been done.
