Dripline Support

HDL - Flush Valve

The Automatic Flush Valve (AFV) allows debris to be flushed out of any dripline system.

  • It is good practice to install an AFV at the end of any single dripline or grid of dripline.
  • Flush the zone prior to use. 
  • An AFV may be used for any dripline system without check valves and will flush the line every time the system starts. Install after initial system flush.
