fresh water pump losing prime/ any ideas
Went on the first trip with the family this weekend and had a great time.
Had to use the water pump and it worked great when the fresh water tank was near full. After we used some of the water ,I would guess 5-10 gallons the pump started to loose prime. We had to keep the faucet on longer than desired to work the air out of the pump and build up enough pressure to shut off. If we didn't continue to run the faucet the pump would keep running becuase it was not primed "air trapped". I could not see any leaks. Is there a check valve between the pump and the tank? Why would the water on inlet side of the pump drain back into the tank? Any ideas ??
