Sounds like the pipe your referring to is your overflow tube for your freshwater tank.
It's possible that your City water fill valve may be malfunctioning and allowing a small amount of water to bypass into your freshwater tank overfilling slowly to the point of it seeping out the overflow. Also, the check valve built in to your water pump can go bad and allow water back into your FW tank when on city water. The best way to tell if either of these is your problem is to totally drain your Fresh tank and then monitor your guages when connected to city water and see if the tank is slowly rising, or just leave the valve open to your freswater drain and watch for a slow drip while connected to city water. Both ways will verify you have water feeding back while on city water.
