I have a Cardinal 37'RK and can NOT get the water to pump out of the fresh water tank.
I have filled the tank to overflow.
Made sure the little vent hose is clear (water shoots back out and I can feel the air coming out as the tank is being filled.
I can disconnect the hose from the tank, hook it to another source of water and the pump will pump the water thru the system.
I can't SEE the tank so where is the tank located?
So what next?
