The water is running well from the hot water faucet, but how does the tank get filled for a shower?? Does the house water auto fill the hot water tank?
When you either hook up to an outside water source, or use the pump and on-board water, your water heater will automatically fill. Just make sure you close the bypass valve and divert the water to the tank.
It may be un-necessary, but anytime we hook to a water source, I bleed any air that may be in the water heater tank. I do this, by opening the hot water valve at the kitchen sink. I let water run, until I'm satisfied that there is no air in the tank.
Hope this helps...
