Hi
I have a Delta shower faucet - brand new, just installed.
I turn only the H supply line on. C is turned off.
When I install the valve correctly with H on the left side, I do not get any water.
When I install the valve incorrectly with H on the right side, I get hot water when I first turn the knob (supposed to be cold).
I have tried 2 different brand new valves. No success. Valve RP46074
Any idea what is wrong?

Thanks
Brett

The system is working as it should...it's a pressure BALANCED valve. For it to work, it needs pressure on BOTH sides.
