When I turn on the faucet to fill the tub, water also comes out the shower head.
The water is not a lot but it drips on the tub spout and splashes on the floor. Amount of water from shower head varies depending on the position of handle, about half way up it is stronger then when handle is all the way up. The tube spout was replaced but no help.
How do I fix this problem so no water leaks out of shower head while filling the tube??
