No hot water (at all) -- Moen Brantford Posi-Temp Single-Handle Tub/Shower Valve
There is no hot water. Period. When I turn on the faucet there is only cold water. If I turn the handle all the way counter-clockwise, the water flow stops completely -- not even cold water. There is hot water in every other sink/shower in the house (including the sink in the same bathroom). This particular shower faucet is not used often (thank goodness) because it is in the guest bath -- but I have a guest coming! Help, please.
