Flowguard™ Check Valve Adapter

Plastico offers two complementary adapter families for protecting irrigation systems against unwanted reverse water flow. The proven Anti-Siphon Adapter series is designed for standard outdoor hose faucets, while the newly developed Flowguard™ Check Valve Adapter provides higher-flow, one-way protection for drip irrigation, multi-zone and sloped installations.

NEW Flowguard Check Valve Adapter
PD-8110 (NH x NH) / PD-8210 (NPT x NPT)

  • Recommended for multi-zone and sloped irrigation systems
  • Operating pressure: up to 100 PSI
  • Flow rate: up to 17 GPM
