I have a 73' Ambassador, on a recent trip we were to far away to hook up to the water supply. I filled the holding tank with our water carrier, so we could have water for the toilet & sink (not to drink). (i bought a longer hose the next morning, LOL)
Anyway all i could get was vibration and noise out of the 12 volt
pump, which i assume is original. Does it need to be primed or did I have a valve in the wrong position?
The control panel showed 1/4 tank & the pump would come on when i flipped the switch. Should i replace the pump or????
