Abstract: Embodiments relate to a system configured to provide communication alerts for a backflow preventer. The communication alerts can be alerts regarding tampering with and/or improper operation of the backflow preventer or a component of the backflow preventer. The system can further be configured to record and track performance measures of at least one backflow preventer within a system of backflow preventers. In some embodiments, a first network of backflow preventers can be established to communicate with a second network so that communication alerts can be disseminated to appropriate individuals for enhanced tracking, monitoring, and/or maintenance of the backflow preventers. Some embodiments of the system can include transmitting a command signal from a computer device of the second network to the backflow preventer to control aspects or components of the backflow preventer.

Abstract: Embodiments relate to a leak detection device. In some embodiments, the leak detection device can be used within a backflow preventer to detect faulty or degraded operation of the backflow preventer or plumbing system instability. Embodiments of the leak detection device can include a movable magnetic element and a reed switch or electrical conductor element. When a leak occurs, fluid causes the movable magnetic element to move relative to the reed switch or electrical conductor element and cause the reed switch or electrical conductor element to generate a signal.
