Bill, it's either the check valve in the pump or the Anderson valve. More than likely it's the pump. You might consider heading over to the Heartland Owners for much more discussion of this problem. A check valve can be added without doing any cutting of existing pipes. Good luck.

When we had this problem (after a few days on city water the fresh water tank would start overflowing) it turned out to be the ball valve for switching from city water to tank fill. It was leaking slightly. Replaced valve and all is well.

Thanks Mel, that should be easy to install.

Has anyone used the "shark bite" brand of check valve? This type should be super easy also, just cut the pex and slip it in.

Yep, same exact problem.

Same problem on my unit, used pump to flush it, no help. Finally turned off city water, turned on pump and opened winterizing valve to suck in air briefly. This has fixed the problem, for now. Seems to have cleaned valve.

I even took my pump apart and cleaned it out (didn't really see anything in it) and it still leaked so I installed a shark bite inline check valve in the pex line between the pump and tank. Two days later and the system is still holding pressure and no longer leaking back to tank. Super easy to install, used PVC cutter and slipped in the shark bite valve. Took less than five minutes.

There should be no way that the "City Water" could be flowing into and filling the RV water tank. I haven't had time yet to take in for repair. Just wondering if anyone else with a Heartland rig has had the same problem. There should be some sort of check valve that would not allow the city water to flow into the RV water tank. I'm guessing a bad water pump in the RV.

Just a follow up.
Took the rig back to dealer for repair. Worked fine....for a couple of trips, then the same problem. I went to Lowes, bought a valve to restrict the back flow and installed it myself. Owning an RV requires a person to be a "jack of all trades".
