It can only get in the tank through the pump. There is no other avenue from the city water connection to the fresh water tank.
You could:
Replace the pump
Take pump apart and rinse all parts off. This may fix it.
Install another check valve
Install a manual valve
Not true, my tank is filled from city water connection and has nothing to do with the pump, I have to open the tank valve to fill tank or close it to use city pressure.
Your pump has a check valve, if that check valve fails the tank can fill by flowing backwards thru the pump.
My tank has a ball valve on it and can not fill unless that valve is open. The check valve in the pump has nothing to do with it. If I'm on city water the tank valve is closed and completely isolated from water system so pump check valve or not it can not fill.
Then your system is unique and not like every other RV built.
