A backflow prevention device for use with a conventional washing machine system that is uniquely designed to automatically disrupt the power to the washing machine should the drain line leading from the washing machine become clogged. The backflow prevention device includes an internally mounted micro switch that is operably interconnected with a portable ground fault circuit interrupter plug that is connected to a duplex outlet. The washing machine is connected to the ground fault circuit interrupter plug so that, upon being actuated, the micro switch will cause a low voltage default to be sent to the ground fault circuit interrupter which triggers it in a manner to automatically cause an interruption of power to the washing machine.
