Wilkins’ next generation backflow preventers are designed for easy handling and maintenance. They have shorter lay lengths than traditional backflow preventers. They are also lighter, since the main valve body is made of FDA-approved reinforced nylon.

Valve maintenance is easy—the test cocks are located on top of the valve for quick access. Plus, you can remove the entire flow assembly for easy maintenance and repair.

Materials: lead-free cast bronze body with reinforced nylon housing; Delrin® and nylon internals; silicone seat discs; Buna-N O-rings; 300-series SS fasteners, springs and struts; lead-free cast bronze ball valves.

Standards & Approvals: ASSE listed No. 1015, IAPMO listed, CSA certified B64.5, AWWA compliant C510, USC FCCCHR approved, NSF listed 61 & 372.
