This 2 1/2" double check valve backflow preventer assembly is designed to prevent the backflow of polluted water from entering into the potable water supply due to backsiphonage and or backpressure in accordance with national plumbing codes and water authority requirements. It is ideal for protection in continuous pressure piping applications and at cross-connections identified as non-health hazards and for other non-toxic contaminants at the service line entrance. This assembly consists of a fused epoxy coated cast iron body using ArmorTek(TM) coating technology for advanced corrosion resistance construction, domestic non-rising stem resilient seated gate valves, top mounted test cocks, two in-line independent positive seating check modules, captured springs, replaceable check discs and seats, and cast iron strainer. The coating on this backflow assembly uses ArmorTek technology to resist corrosion due to microbial induced corrosion (MIC) or exposed metal substrate.

• Utilizes advanced ArmorTek coating technology to resist corrosion of internals
• The valve body shall utilize a coating system with built in electrochemical corrosion inhibitor and microbial inhibitor
• Domestic non-rising stem gate valves
• Non-health hazard application
• No special tools required for servicing
