This 2 inch double check detector backflow preventer assembly is designed to prevent the reverse flow of fire protection substances and water of non-potable quality from being pumped or siphoned into the potable water supply due to backsiphonage and or backpressure in accordance with national plumbing codes and water authority requirements. It is ideal for protection at cross-connections identified as non-health hazards such as on fire protection systems and from other contaminants found at the service line entrance. This compact modular design with a single access cover for easy maintenance is approved for horizontal and vertical flow up installation. It consists of a cast bronze body, outside stem and yoke resilient seated gate valves, captured spring check valves, and four test cocks. It comes with a gallon per minute meter to detect underground leaks and unauthorized water use. The double check valve includes a freeze sensor for use with SentryPlus Alert(R) technology to signal facility personnel when temperature nears and reaches the freezing point. Freeze alerts feature available with add-on connection kit for building management systems (BMS), irrigation management systems (IMS), and Wi-Fi networks.
