Hi All,
So I am using the fresh water tank instead of hooking up to city water. I notice every so often I heat my water pump click on for a few seconds while I am not using any water. It quickly turns on and shuts off. Could I have a leak somewhere in the fresh water system? When the pump sense this small change in water pressure and energiz? I don't use the ice maker anymore and toilet level always stays the same.
Thanks
Jason

You could have a leak, but often such symptoms just mean a faucet somewhere isn’t fully closed. Check any outside “shower” shutoffs and that the water manifold drain valves are fully closed. Then feel around the pump’s fittings for dampness. After that I reckon I’d start looking behind drawers and cabinets for any sign of fitting failure, especially any newly worked on area or appliance.

Jason,
Two other possibilities are the check valves inside the water pump and the check valve inside the city water connection. To isolate the problem, if you can remove the output water line from the pump and temporarily install a female cap. If it continues to cycle it is the pump. If it stops cycling, you have a leak somewhere. A 30 year old coach has more potential of a leak. The water line to the ice maker is a good place to look. Hope this helps, Fred

When our water pump cycled every few minutes, we found a split in the small, plastic water line that feeds the ice maker. The split was near the propane flame that heats the fridge's cooling system. You say you're not using the ice maker but did you turn off the water supply valve feeding the ice maker. Our supply valve is in the box with the freshwater pump. Anyways, when we removed the exterior access panel behind the fridge, it was obvious there was a "squirter." Other than that, as previously stated, look for a dripping faucet; a dripping valve on the clothes washer, dish washer, or toilet; a dripping splice on a water line; or a failed back-flow valve in the freshwater pump or water-fill valve.
