RV Fresh Water Overflow - RV Water Pump Valve

RV Fresh Water Overflow - RV Water Pump Valve

In this video, Sharon shows you the fix she found for our fresh water fill overflowing.

(If you are in a hurry, skip to the end of the video where the steps involved are listed.)

The water pump and the hoses around it were completely dry, but there was a problem. Sharon placed a call to Winnebago, and she was thrilled to talk with a real person who spoke with two techs -- all in under five minutes.

Before Sharon bought a water pump, she saw another video with an easier approach to the problem. On this trip, once we got set up, we did NOT turn on the city water.

There is a valve either inside or connected to the water pump that sometimes gets stuck open. That allows the city water to backflow through the water pump and down into the fresh water tank.

The valve can get stuck open anytime there is air in the lines. If you don't have the water connected to city water and you don't have the water pump on, but you turn on a faucet, you may get air in the lines.

The first thing you want to do is have the city water connected but turned off, and second, turn on the water pump. Step three is we're going to let that pressurize by leaving it on for 10 minutes or so.

Next turn the water on at the faucet that is farthest away from the water pump. Let the water run until there is a strong flow with no air, no spits and sputters.

Just to be sure all of the air was out of the lines, we repeated the previous step with all of the faucets.
