Faulty pump check valve?

Out camping and just noticed my water tank overflowing, but I didn't fill it and it was empty before we left. I'm assuming that the check valve on my pump is faulty and the city water connection has filled the tank.

Is this something I need to deal with right away, or can it wait?

Pump valve rebuild kits available. Or the pump may just need to be cleaned out. Debris in the rubber valves.
Do you have a strainer housing on the inlet side of the pump ?
Worth installing one if you don't have.

You do need to deal with it cause it will keep filling the tank. You could just plug the hose and cap it off.

City water is filling the tank because the "city water/fill fresh water" valve in the wet bay is a justa wee bit open or it has a bit of grit in it. Crank it back and forth a few times. Worked for me!

Your assumption is probably correct. I had the same problem last year. I pulled the pump and disassembled it. The rubber diaphragm was deformed. No repair parts available for that particular pump so I replaced the entire pump.

You could also solve the problem by installing a check valve in the line on the output side of the pump.
