The Ames Fire & Waterworks Series 5000SS Reduced Pressure Detector Assembly, 4 inch, with OSY shutoffs, cubic feet meter, and flood sensor, is designed to protect drinking water supplies from dangerous cross-connections.

This backflow preventer assembly prevents the reverse flow of hazardous materials into the potable water supply due to backsiphonage or backpressure, ideal for health hazard applications in continuous pressure piping systems such as fireline, irrigation, or industrial processing.
