Abstract
The present disclosure is directed to systems and methods useful for backflow prevention system that includes an actuated valve, a valve controller, one or more upstream sensors, and one or more downstream sensors. Upon detecting conditions conducive to backflow through the system using either or both the one or more upstream sensors, and the one or more downstream sensors, the valve controller causes the actuated valve to close. The system may be enhanced through the use of a qualifying check valve disposed between the actuated valve and the one or more downstream sensors to slow or impede backflow through the system. The system may be enhanced by inclusion of a run-out length between the actuated valve and the one or more downstream sensors to account for the latency in the actuator causing the valve to transition to the CLOSED position.
