This Colt™ 3 inch double check detector backflow preventer assembly is engineered to safeguard drinking water supplies by preventing the reverse flow of non-potable fire protection substances and other non-health hazard contaminants into the potable water system due to backsiphonage or backpressure.

It is specifically designed for non-health hazard applications such as fire sprinkler systems where water monitoring is necessary to detect unauthorized water use or underground leaks.
