Backflow Preventers

Part Numbers # 270298, 270299

Chemical management made simpler, neater, cleaner and safer - Lafferty. In addition to supplying spare parts for all Lafferty equipment, Lafferty offers many convenient accessories to complement its wide range of chemical application equipment.

Key Features
  • Designed for use on non-health-hazard, continuous pressure, point-of-use applications for protection against backsiphonage and backpressure
  • When installed upstream of a water-driven foamer or sprayer this part will prevent chemical solution and/or compressed air from backing-up into the water source in the event of reverse suction (power failure, improper operation, failure to close inlet ball valves, etc.)
  • In the event of reverse suction, backwards flowing water, chemical, and/or compressed air will discharge from a vent on the side of the backflow preventer.  If desired, this vent can be plumbed to direct the discharge to an appropriate drainage area.
  • May be mounted horizontally or vertically
  • Available for 1/2" or 3/4" plumbing
**Install in accordance with local plumbing codes**
