I have a 2000 Lance 820 that I purchased last fall. When I filled up the water tank and tried to get water flow from the faucets, nothing happened. The pump is running and when I put the valve under the sink in the "winterize" position you can hear the pump pushing air through the line. Any suggestions?
You might try opening all of the faucets in the RV to try to get the prime back. Another trick is to elevate the anti-freeze line and add water to it to put pressure on the inlet side of the pump for the same purpose.
