Abstract
The backflow valve of the present invention includes a valve housing having a cavity therein with an inlet and an outlet to the valve cavity. A switch is in communication with the valve cavity and is moveable from an off position to an on position in response to liquid filling the valve cavity. A valve is moveable in response to the movement of the switch to the on position. The valve moves to a closed position shutting off the fluid flow through the backflow valve.
