fresh water pump not working
[Gary B] Brain, check to see if a bypass valve is open, either for the water heater, or a tank / line drain etc. This happened to me last winter on our way south, when we got to warmer weather I put water in the tank, went in and turned on the pump, got a little squirt of water then nothing, pump was running, it was dark and I saming oh no. Finally discovered I hadn't closed the valve for filling the tank, and the pump was just ciculating water in a small cicle. Good luck GB
