I own a 1998 manufactored home and i recently discovered i have a water leak between my guest bathroom wall and guest bedroom wall. I opened up the wall and have found out that the faucet is plastic. The kind with a pull up thing for a shower. The place were the lines attack dont leak but if i reach up behind the tub near the back of the faucet and turn on the hot water or the shower i get a very wet hand. Do i need to replace the faucet? Does anyone know what could be causing this?
