Water Pump Not Working

[kcarver]

We bought a used 2008 Casita Freedom. We are starting to un-winterize it. The battery is testing good. The lights inside the camper turn on ok. I filled up the fresh water tank to flush the lines, but the water pump doesn't come on. Don't understand what could be wrong. I flipped the switch to on and turned on the kitchen faucets. But I hear nothing, and no water is coming thru.

Check fuses, voltage at pump, voltage at switch, pressure switch on pump.

And, remove and clean aerator on faucet. If that is plugged with debris, the pump senses back pressure and won't start ( just like a gas pump, shutting down automatically ).

Thank you for the responses. We figured out what happened. Because it had been winterized, we had to hook up the city water and let the water flow in that way first. We also opened up the hot water bypass valve thinking that would also help (not sure if that made a difference or not). Once we did those two things, the pump came on and we were able to un-winterize the holding tank.

Know you fixed it but for general info:

Had to take end off of our pump and clean the little pump diaphragms once. Worked great when put back together. Was a problem with dirt from our water source one summer. Hand pump well to buckets into trailer.

Ours ran but did not pressurize, otherwise would have checked the fuse.
