Fresh water tank keeps filling

[Orrin]

My outback 340BH fresh water tank keeps filling, slowly, while I’m set at city connection. What do I do?

The water pump internal check valve isn’t closing...this allows city water to flow thru the water pump and back fill your water tank...

With city water off and valves set for using water from tank bump the pump off and on with one faucet open ..
Do this several times..

Then drain fresh water tank and leave drain open and turn city water back on with valves set properly city water.

Often just cycling the water pum0 in and off a few times will clear the valve and let it seat.. if problem still continues then remove internal check valve and clean and reinstall

Thanks! I had the same thing happen to my 2020. I toggled the blue handle between fresh and city a few times with the drain open before it closed correctly. Thought I was going to have to replace something.
