Q: Does my JABSCO fresh water pump inlet hose need to be primed, filled with water, in order to draw from the fresh water tank? Pump seems to run fine but no water is moving. Tank is impossible to get to. I disconnect and reconnected the inlet hose and no blockages are visible. Suggestions?

 

A: The pump is self-priming to 1.8m as it says on the details on the website.

If your pump is not priming (and there is water in the tank) it is most likely due to either an air leak on the suction side or the valves in the pump are worn and need to be replaced.
