Why does my freshwater tank keep filling up?

There is a one-way check-valve inside of the water pump and this often gets dislodged and stuck open. When this happens, water from the city water connection can flow backwards through the pump and into the freshwater tank.

What to look for when filling a fresh water tank?

Check for kinks or obstructions in the vent hose between the water tank and the exterior vent which is typically part of the fill assembly on the side of your RV. If the vent is unscreened, insects can nest in the vent line, plugging it in the process. Check for kinks in the fill hose between the tank and the fill opening.

What happens when there is no air pressure in a water tank?

As water fills the tank, air pressure should increase steadily to 35-40 psi, which triggers a check valve that stops water flow into the tank. This also prevents water from draining. If your tank doesn’t have enough pressure, the valve won’t work, and water will keep flowing in and down the drain.
