This Colt Series LFC500 2 1/2 inch Lead Free Reduced Pressure Detector Backflow Preventer Assembly provides critical protection to the potable water system from contamination. It is specifically designed to prevent the reverse flow of non-potable fire protection substances and water from being pumped or siphoned into the drinking water supply due to backsiphonage or backpressure. Additionally, it monitors unauthorized water use from the fire protection system.
