If the pressure is to high at the faucet creating back pressure and I turn down the water at the main water shut off, would that reduce the the pressure enough to stop the water from coming out the shower. I thought that would be the case but I was wrong and water still came out the shower head when filling the tub.
Question: If reducing the pressure there doesn't help then how much help would replacing the Pex line for copper be?
Can anyone she'd some light on my situation. I might add that there is a considerable amount of water coming from the shower head. The shower head mixer and faucet are Moen products
