Key item features

  • Convenient Packaging: This product includes a two-pack of Mueller/B & K Model 108-904RP backflow preventers, each individually packaged for display.
  • Universal Compatibility: Designed to fit any 3/4'' hose thread outlet, these vacuum breakers attach to sill cocks, valves, and hydrants with male hose thread outlets.
  • Contamination Prevention: The primary function is to prevent the back siphoning of contaminated water and dangerous backflow into a potable water supply.
  • Safety Standards: Hose threads comply with ANSI B1.20.7, and the device is ASSE 1019, I.A.P.M.O., and A.S.S.E. approved for reliable performance.
  • Installation Flexibility: Suitable for both indoor and outdoor use, it includes a break-away lock screw for optional vandal-resistant installation.
  • Manual Drainage: The outlet side features a manual drain release for the check valve, allowing complete draining to prevent freezing in non-freezing areas.
