The tub faucet in our second bathroom has been loose for some time. I finally had a plumber come out and he said the piping isn't properly secured behind the wall. We currently don't have an access panel so he said he will need to go through the drywall behind the shower in order to fix it. Before I let him do this work I just wanted to get a second opinion. If that's the only solution then I'm fine with that, it just makes me nervous to go through the wall and then have to fix that once he is done. Thank you for any advice!
