Pressure Balanced faucet question
We just had a pressure balanced tub/shower faucet installed in our bathroom, and something is wrong, but I'm not sure what. When testing it, we turned off the hot water going into the bathroom, and now no cold water comes out of the tub/shower either. So my biggest question is, is that normal? Do Pressure Balanced systmes shut off the cold water too when the hot water is shut off?
The big problem we are having is that the pressure in the tub/shower is very low, especially for the cold water. In the sink next to the tub, hot water comes out of the cold water tap, but if you run it for a while, it turns cold. I suspect these problems are all related.
I would apprecaite any suggestions.
