water pump

[ezgoin]

Getting ready for our first long trip. We went to the park and checked everything. The water pump worked fine hookeed up to city water. We are trying to get the water to work from the holding tank. No go. Don't know what to do, or where the water pump is located on our 2008 Georgetown. Any help would be appreciated. Thanks

your not supposed to use the pump when hooked to city water. I assume there is water in the tank? Does the pump run?

Did you fill the fresh water tank? Did you turn on the water pump? Is the winterizing valve closed?

To repeat Flybob's question: Have you turned the water pump on?

Here's an explanation, if you don't know how it all works:

Power to the pump runs through a main switch and a pressure switch. When the main pump switch is turned ON, and pressure in the water line is low, the pressure switch closes and starts the pump. When the pump brings the pressure up, the pressure switch opens and turns the pump off. City water pressure is higher than the setpoint of the pressure switch, so city water will always keep the pump from running (unless you put a REALLY large demand on it by maybe opening every faucet - I'm assuming you're not doing that).

So, if you were hooked to city water previously, the pump should not have been running (even if the main switch was turned on), as the higher city water pressure should have opened the pressure switch that controls the pump, keeping the pump off. Now that you're off city water, the main pump switch must be turned ON, then the pressure switch will turn the pump on and off as needed to keep the pressure up.

The main pump switch should be on your main panel somewhere; probably next to the tank level indicators.

Thanks for the information. We filled the holding tank, then flipped the pump switch and opened up the faucet and no water or pressure.

You have to wait. If the water heater is empty you have to pump 6 gallons of water into it before you will see water. if the RV is new and was winterized, check to see that the winterizing valve ( where the antifreeze is introduced) is closed or the pump will just pump air. If everything is off and quiet, you should hear the pump run. Is the pump running.

If the pump is running, you should be able to hear it. (Many folks complain because they tend to be noisy!) Being you have a 2008 model, it's possible the pump is fried; could be the fuse, also.

Did you turn the valve from city water to fresh water tank.
