Series LF007 Lead Free* Double Check Valve Assembly Backflow Preventers are designed to prevent the reverse flow of liquids in a plumbing system due to backpressure or backsiphonage where there is a non-health hazard. Their compact design makes them easy to install in tight spaces. And the single cover, top-entry design allows convenient access for maintenance. The seats and seat discs are replaceable, and no special tools are required for servicing.

For 2 1/2 and 3 inch sizes: the coating on this backflow assembly uses ArmorTek™ technology to resist corrosion due to microbial induced corrosion (MIC) or exposed metal substrate.
