This professional grade anti-siphon valve replaces Rain Bird and other irrigation valves installed above ground with ¾ in. female threaded inlet and outlet. It can be used with any 24 volt AC irrigation timer. Its unique reverse-flow design helps prevent flooding in the event of internal diaphragm failure, keeping the valve closed and saving water. The Jar-Top bonnet quickly allows quick access to the diaphragm for easy maintenance. Anti-Siphon valves should always be installed at least 6" above the highest head on the valve line, and should never have another valve installed further down the line from the main valve. After installation and before startup, always the flush system of dirt and debris manually using the valve's external bleed screw.

  • Anti-Siphon (above ground) mounting
  • 3/4 in. female threaded inlet and outlet (use 3/4 in. MPT threaded pipe adapters with Teflon tape)
  • Jar-Top bonnet simplifies cleaning and maintenance
  • Flow control allows adjusting flow to the zone, optimizing sprinkler performance
  • 24 VAC, 50/60 Hz automatic operation or manual activation with bleed screw
  • Buna-N diaphragm offers superior performance in harsh water environments
  • External bleed to manually flush system of dirt and debris prior to installation and system start-up
  • Spray-free internal bleed for manual operation
  • Energy efficient, low power encapsulated solenoid with captured plunger for long lasting dependability

Rated 1.0 out of 5.0 by Don't buy. Junk I installed 6 of them for different zones of the garden. all the valves are open and will not turn off. I have to turn off the mail water to shut the water. I will have to replace all of them. DO NOT BUY THIS PRODUCT May 31, 2016
