If you have a valve to allow you to fill the tank from the city water hookup, it's leaking. If you don't have that valve, then the check valve in the water pump is leaking.
Correct......
2 methods of water leaking into fresh water tank.
'Fill Valve' OR pump internal check valve
Disconnect pump suction line at pump, turn on city water and see if water backflows thru pump
If thru pump.....running it, using the water in fresh water tank can flush any debris/deposits on check valve diagram.
Otherwise....replace pump.
If 'Fill Valve'----replacing it best cure
