Product Overview

This residential and light commercial grade in-line anti-siphon valve replaces Rain Bird and other irrigation valves installed above ground with 1 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. This valve can be applied with all types of watering devices including Rain Bird spray heads (1800, 600), and rotors (22SA, 32SA, 42SA+, 52SA, LG3 and AG5). Use anti-siphon valves in locations where the use of a pressure vacuum breaker (PVB) or a double-check valve is not required by city codes. Check your local city codes to determine what type of valve is required. Anti-siphon valves should be installed at least 6 inches above the highest head on the line, and should never have another valve installed further down from the main line. After installation and before startup, always the flush system of dirt and debris manually using the valve's external bleed screw.

  • Designed for anti-siphon (above ground installation) with approved back flow prevention device (not included)
  • 1 in. female threaded inlet and outlet
  • 24 VAC, 50/60 Hz automatic operation or manual activation with bleed screw
  • Buna-N diaphragm offers superior performance in harsh water environments

Customer Questions & Answers

what is the wire for?

Asked by: RC
The wires that come out of the top of the solenoid are run to the irrigation controller. The controller powers the solenoid and turns on the valve according to the watering schedule.

is there a pressure regulator that can attach to it

is there a pressure regulator that can attach to it
Asked by: jr
There isn't a pressure regulation device that can attach directly to this valve. A separate pressure regulating device would have to be used.

They were replacements for older valves and needed the appropriate spacing. 1 was defective. It would not close, I followed the directions - no change. I opened and carefully inspected and cleaned it - no change. Of course HD return policy allowed me to get a new one. They are also very sensitive to having any sprinkler heads above the location of the valve. Well, I'm sorry but it is not always possible to stick the valves in locations above the sprinklers - this defect should be corrected. Jar tops are easier to service than those with multiple screws.

Rated 4 out of 5 by from Great product Good product for the price. I would of liked a flow control valve. Easy install and trouble free maintenance.

Rated 2 out of 5 by from Will be replacing next year I found the so-called easy install instructions useless and had to hire somebody to install for me. I frequently need to water manually & expected this to be as easy as my old valve I had which had a tiny flip-up lever. The product states this is an easy tool-fee feature for manually watering, HOWEVER, the valve is soo tight it's almost impossible to move manually. I will need to use a wrench whenever I want to water manually. I'll probably replace them all next year for something else
