This is ambiguous. There is a city water inlet and a tank fill inlet. (Not all rigs have a separate tank fill inlet.) If you connected to the city water inlet, then you do, indeed, have a backflow preventer in the water pump that has failed. If you connected it to the tank fill inlet, you need to stand there while it fills till water comes out the inlet and vent, then turn the water off.
The units without a separate tank fill inlet have a valve that you turn to switch between city water and tank fill. If that valve is turned wrong, that will happen.
