This is an extremely common problem. As noted, its a leaking check valve in the pump. You hook to city water and your fresh water tank slowly fills and overflows.
Remove the city water altogether and then run the pump extensively by opening faucets. Shut the pump off, and reconnect your city water. It probably will be ok after that.

Zillions of Youtube videos about this. Here is one that covers it pretty good.
