When I put my shower on there's a water leak on the other back side of the shower.I have another bathroom it gets wet this only happens when the shower is on. I have noticed this. Ive tried to locate the leak it is small leak. Is there a gasket somewhere on the shower valve im missing? Please help!!!!
As you turn on your shower you add pressure on the pipe leading to the shower head. there could be a pin hole on the water line or a solder joint has failed. if you have tile on the wall remove one and take a peek in the wall or look in the wall on the back side . theres no easy fix with out get to the inside to repair it dont wait to long or it will begin to mold inside the wall
