Help w/ water pumping issue...

Your feed line from the Fresh tank to the pump has a open. It is allowing air to be drawn in along with water. It can be a loose clamp. It can be a Pick up tube that has fallen down in the tank. Some RV's use a pick up tube like a gasoline tank sending unit in cars. The most common cause of this is IF you have a winter bypass valve kit, that valve is open or partially open. QUICKEST way to confirm your type problem and NOT waste time swapping and buying new pumps:B , is to take a 1 to 3 gallon water container and run a short hose from it to the input of the pump. THAT will tell you if you have a defective pump and confirm it is the FEED from the tank. Also, another common cause of this type problem is the input filter connected to the pump. IF NOT winterized(drained) it will crack and usually not that visible. It will NOT leak water when attempting to draw water, but will allow that air to be sucked. Doug
