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.

Customer Questions & Answers

Can these valves be installed on the wall in the garage?

Asked by: Mel862
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.

i am trying to find a valve that will pump enough water for long runs

i have a very long run with 34 plants that i am watering around the house. The first 15 plants get plenty of water pressure then it seems to barely come out at the end.
Asked by: Rick
It's not about the valve when analyzing pumping pressure. It's about the water pressure feeding the valve. The valve will OPEN regardless of pressure behind it, but you do need some type of pressure. Normally, once your valve is installed, you manage the water pressure by adding a "pressure regulator" which "follows" this valve - which will manage the water pressure that is watering your plants. Installation normally goes like this (for a drip system): main water source, valve, pressure regulator, drip system, drip controllers (0-6 gph).... The drip controllers you have to purchase at the store and you buy each controller that will provide exactly enough drip for each plant! Look it up on Google (drip system installation plans).

Is the distance between the two piping holes the same as that of a brass valve?

Is the distance between the two piping holes the same as that of a brass valve?
Asked by: Josephen
Many valves have varying distances between the inlet and the outlet so proper planning has to go into the replacement of an old valve. If PVC piping is being used it might need to be reworked to fit the new distance. Just be sure to paint the new PVC so it is not exposed to the sun making it brittle under pressure. This valve has an inlet to outlet distance of approximately 3.75" measuring from the center to the center.

It is much more heavily constructed. I have two of the regular valve, which have worked flawlessly for years. I recently replaced a very old valve with one of these, and I expect it to last for many years.

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.

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.
