Abstract: A backflow preventer for preventing a reverse flow of water in a plumbing system including a body having an inlet and an outlet. The body forms an intermediate zone between the inlet and outlet. An inlet check valve prevents the reverse flow of water from the intermediate zone through the inlet. An outlet check valve prevents the flow of water from the outlet into the intermediate zone. An inlet pressure sensor, an intermediate pressure sensor and an outlet pressure sensor provide readings for the respective zones. A controller monitors a pressure differential between the outlet pressure zone and the intermediate pressure zone to compare the pressure differential to a pre-set range. The controller generates a warning/error message when the pressure differential is outside the pre-set range. The controller can also monitor an inlet pressure in the inlet zone to generate a message if the inlet pressure varies inappropriately.

Abstract: A sprinkler backflow alert system includes a sprinkler system, a building fire panel, a backflow preventor including at least one shut-off valve, a fluid detection system, and a tamper switch. The backflow preventor may be fluidly coupled upstream of the sprinkler system. The fluid detection system is configured to detect a discharge of water from the backflow preventor and generate a water discharge signal corresponding to the backflow discharge. The tamper switch is configured to detect a change in a position of the at least one shut-off valve and generate a tamper signal in the event the at least one shut-off valve is closed or partially closed. When a backflow discharge event occurs, a signal is sent to the fire panel triggering the building fire alarm as well as sending an alert to the local fire department and facility owner.

Abstract: Systems for isolating a region of a water distribution network are disclosed. In embodiments the systems and methods utilize at least one control valve system that includes a valve, a pressure sensor, an actuator, and a controller. The controller determines a water pressure at the control valve system based at least in part on a sensor signal from the pressure sensor. When the detected pressure is less than or equal to a low pressure threshold the controller issued a control signal that causes the actuator to move the valve to a fully closed position. Multiple control valve systems may be employed to isolate a region of a water distribution network. Methods of isolating a portion of a water distribution network, water distribution network including a control valve system, and control valve systems for use in water distribution networks are also disclosed.
