Water Pump

I checked for water leaks and don't have any. However, when everything is turned off, water pump goes off about every 15 minutes for 1-2 seconds and is annoying when sleeping.

We are on a 5 week road trip and this started after around 7 days into the trip.

Any help is appreciated.

Thanks

Here are a few things to check:

1) Take a look at the city water inlet. Is there water around it? If so, you could have a leak on the one way valve in there.
2) Another thing is to check to make sure your hot water take pressure relief valve is not weeping. Sometimes they go bad and leak enough to bleed off pressure.
3) Check all the sinks and toilet water connections. Sometimes they work loose which let's pressure bleed off.

Make sure you bleed ALL the air from the system. Including the exterior shower if you have one.

You are losing pressure somewhere in the system...obviously.

Are you boondocking all the time?

If you are connected to RV park water supply you don't need the pump turned on.

Until you find the problem I'd shut off the pump at night, turning it on only if you used the bathroom.

I had a similar situation on my Endeavor when I first bought it. Looked all over the coach and didn't find anything. One day I had the fridge access door off and noticed there was a pin hole leak in the ice maker line. It was leaking into the fridge drain pan so the leak really didn't show up anywhere.

If your pump is cycling on it has to be losing pressure somewhere. You could cap the pump outlet and see if it cycles. That will eliminate the pump from the equation and you can move on with your search.
