I have a problem with the hot water in my guest bathroom shower stall fixture. The fixture is a Danze single-handle unit.
When I turn the shower on, plenty of cold water comes out, no problem. But when I continue to rotate the lever all the way around to the point where the hot water should come out, there is an audible sort of thunk in the line and I feel a jolt in the handle; the water volume is reduced probably by 75%, and only cold water comes out.
Our hot water source is a Noritz tankless gas water heater, located on the outside of our house. The discharge temperature is set at 120F.
Since the Noritz tankless system obviously can not select where it is sending the hot water, and every other hot water outlet in the house works fine, I suspect that the problem must be in the Danze fixture. So I replaced the cartridge in the Danze fixture with a new one, but the same problem persists.
Can anyone help me?
