HELP! City water running and water pump won't off.

[philhyde]

This evening we arrived in Los Angeles after several long travel days from Oregon. After connecting the city water, I noticed that a 'running' noise was coming from behind the RV connections (behind the panel where the city connection is and near where the water pump is). After running around like mad trying to make sure all of the faucets were turned off, we were completely stumped how the water was still running, and more importantly, where it is going.

While we were standing there, the fresh water filler vent spurted water and started to gurgle. The same gurgle that is heard when the tank is being filled from the outside. My RV also has a "power" fill valve which seems to divert water from the city connection into the fresh tank.

So, it would seem that the fresh tank is being filled by the 'running' water I am hearing. Since I assume the water pump can pull from the fresh tank, my only guess is that some part of the pump failed which is allowing water from the city side back through the pump into the fresh tank. Does this make any sense?

Any other suggestions?

Thanks in advance...

It's possible the check valve in the pump is bad. In over 12 years of full timing we have had that happen to two pumps.

Check you holding tank fill valve in the convience center. Bet it's not set to city water but to the holding tank fill position.

Sounds like the Power full value is in the fill position. Pump will run it you are filling the fresh water tank.

After you check and make sure all your settings are correct to run off city water then cycle your pump on and off a couple of times. If it is a check valve that may free it up, not sure it that works but it's an idea....

Thanks. I did check the city fill valve and its in the right position.

The water flowing noise is coming from the pump so that seems like the likely culprit.

Replacing the pump solved the problem. In the process I upgraded to the "quad" pump from Flojet.

Thanks for your replies!
