Fresh Water Tank

[Loving Life]

Our fresh water tank seems to be "filling itself". After being hooked up to water at a campground (putting NO water in the fresh water tank); water seems to be seeping back through the pump and putting water in the fresh water tank. We have had multiple campers and this has never happened. Thoughts or ideas?

I would think that your water pump has a bad check valve, allowing water to go back to the draw line side and putting water in the tank instead of drawing from it, Even though you are on city water. Pretty sure it is a bad water pump.

X2, but I think you can replace just the check valve and not the whole pump. In the interim I there is a valve down by the pump that you can close and it will keep water from going back to the tank. It is supposed to keep the pump from drawing tank water when winterizing.

X3 the Water Pump Check valve. Had the same issue and just closed that inline valve. Just remember to re-open that valve if you move and plan to use water from the fresh water tank.

Mine did this once and hasn't done it again.

Mark, that's a good point -

I'm certainly sure it could be some sediment caught in the check valve and drawing water from the tank might clear it up so it works fine the next time. Hard to say, but worth a try!

Try shutting off the city water and draw from the tank for a bit to clean out the check valve.

Thanks for the great ideas. We'll try them in a week or so--after Phoenix RV rally.
