This Colt™ 8 inch lead free double check detector backflow preventer assembly (DCDA) is designed to prevent the reverse flow of non-potable water and fire protection substances into the potable water supply due to backsiphonage and/or backpressure.

It is primarily used for cross-connections identified as non-health hazards, such as on fire sprinkler systems, and to monitor unauthorized water use or detect underground leaks at the service line entrance.
