Product Overview

This professional grade anti-siphon valve replaces Rain Bird and other irrigation valves installed above ground with 3/4 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. Anti-Siphon valves should always be installed at least 6 inches 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. Equipped with the additional advantage of adjustable flow control, this model helps prevent wasteful misting when water pressure is too high. A top mounted, easy turn flow control knob allows you to optimize flow to the zone, permitting sprinklers to water at their most efficient rate for more uniform coverage. 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) as well as Drip zones when properly installed together with a pressure regulator and filter.

  • Anti-Siphon (above ground) mounting
  • 3/4 in. female threaded inlet and outlet (use 3/4 in. MPT threaded pipe adapters with Teflon tape)
  • 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

Answer: 
They can be installed anywhere, as long as you have a method of draining the water that will initially blow out of the anti-syphon part of this valve. When the system first gets pressure from the solenoid valve opening, the onrush of water pushes up against a float that then seals off the anti-syphon device and permits the water to flow down the hose to your sprinklers.

They can be installed anywhere, as long as you have a method of draining the water that will initially blow out of the anti-syphon part of this valve. When the system first gets pressure from the solenoid valve opening, the onrush of water pushes up against a float that then seals off the anti-syphon device and permits the water to flow down the hose to your sprinklers. However some water initially blows by the float until it seals off and will blow out on your floor or the ground if it is outside. It blows over about a 2 - 3 foot radius, depending on water pressure. Read Less

Answer: 
You can install these wherever you want, however keep these in mind:
1. The valve must be installed above the highest output point (sprinkler, emitter, etc) for the anti-siphon to work. If it is below the point, water will always gush out when the system shuts off.
2. The valve needs to be installed up-right on pipes so you can't really just stick this to the wall... You can mount this near a wall but

3. The valve's anti-siphon device may gush water out sometimes so make sure to keep the valves away from anything that could be damaged by water, such as drywall.

Answer: 
Sounds like a pressure problem from the street but could be a volume problem. Serve a 1" water valve using 1" water pipe. Sometimes we cut cost and use 3/4" lines and 3/4" valves and waste money instead of save money when we don't get the pressure we want.

3/4 in. Anti-Siphon Irrigation Valve with Flow Control is rated 4.4 out of 5 by 22.
Rated 4 out of 5 by from It works Had a previous version installed but was missing the cap, For whatever reason, the cap is almost as expensive as the entire valve, so just went with a new valve. I'm using it manually, so I cant speak to the product as a whole (Hence 4 stars and not 5), but it works perfect for what I need. I lucked out when I purchased my home, although the previous valve was missing it's cap, who ever installed the system did so with the ability to detach one of the pvc pipes that were leading from this valve. My neighbor had a similar problem with his valve, but he had to cut pipes to get it off. Remember this if your installing a new system, or even replacing. Both pipes screw into the valve, and it's 1 piece.

Rated 5 out of 5 by from Pretty good quality . I replaced a valve just like it only because a shovel fell on it and broke the solenoid on top and The Home Depot clerk told me they don't sell parts for them like they used to. So I figured Since I got about twelve years out of the last one, It served me well. These things are pretty tough.

What would make this a much better product would be easier installation. The product should have connectors that screw onto the PVC pipe. If you have a leak after installation, you must cut the valve from the pipe and redo it.

Rated 4 out of 5 by from anti siphon valve This was the reason for the purchase. My old one went out. Now they only last a year but they do get clogged. My husband had to replace one. I told him to do it in pairs. So he did. I wish they lasted longer...

Rated 3 out of 5 by from Good purchase Rainbird makes a good product, BUT, I wish they would continue making the same product. I'm getting tired of having to change the entire valve. I would rather replace the head of the valve, that's much easier but they keep changing the style of the head so you have to change the entire thing. Come on. Make life easier for us not more difficult. You can still keep raising the prices without a redesign. We won't mind that much.

Rated 5 out of 5 by from Pro Grade This valve, if not installed in direct sunlight is a five year plus valve. This valve rates up there with high end Hunter, and Irritroll valves. If you have the extra fey bucks, spend it and you will be worry free for years.
