Additionally, is the intake screen clogged on the pump??? Is the pump running but not pumping water or does it not run at all... Look for a collapsed intake hose... The pressure switch could also be bad... Also looked for clogged intake water lines... Do you have any water pressure at all???
Need a little more information other than it stopped working...
[Brian] The pump is trying to work but nothing is coming out of the taps. Everything was drained over the winter and I was putting it back in service. I put water in directly with a hose to blow out air in the lines and then I put water into the fresh water tank. It worked for a couple of minutes and then stopped pumping (pumnp still works electrically).
[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
[Brian] Gary thanks for your response as it makes sense. I went looking for bypasses and couldn't find any that were open, if in fact they were bypasses. I will keep looking, but my problem still isn't solved.
