Help with water newbie
I would try adding some more water. The design of the FW tank it does bulge downward, and the pick up line from the pump could be elevated slightly above the water level. Speaking of water level......the light indicators are never really accurate. Add plenty water, try again, and check valves as per Lloyds suggestion.
