Description

Rain Bird DASASVF100 Professional Grade Anti-Siphon Valve with Flow Control, 1" Threaded Female x Female. Rain Bird manufactures only the highest quality Anti-Siphon valves. This professional grade valve replaces any Anti-Siphon irrigation valve installed above ground with 1” female threaded inlet and outlet. Unique reverse-flow design helps prevent flooding in the event of internal diaphragm failure keeping the valve closed and saving water. A top mounted, easy-turn flow control knob allows adjusting flow to the zone; optimizing sprinkler performance to avoid misting and provide the most uniform coverage. For use with any 24 volt AC irrigation timer/controller. Features Rain Bird’s patented vacuum breaker with bleed screw for automatic or manual operation. Buna-N (nitrile rubber) diaphragm with water filter and captive spring offers superior performance in harsh water environments. Energy-efficient, low power encapsulated solenoid with captured plunger for long lasing durability. Heavy-duty construction with stainless-steel screws; 1" female pipe thread (FPT) inlet and outlet. Designed to be installed above ground Anti-Siphon valves prevent back flow when properly installed. Install at least 6" above the highest sprinkler head on the valve line; never install another valve further down the line from the main valve. After installation and before startup, always flush the system of dirt and debris manually using the valve's external bleed screw. Flow Range 0.2 to 40 GPM. For flows below 3 GPM or Drip applications install a 200 mesh filter before the valve. Operating Pressure: 15 to 150 psi. Meets I.A.P.M.O. and A.S.S.E. listing specifications. Canadian Standards Association approved. Also available (sold separately) in 3/4” model: DASASVF075.

Professional Quality and a Great Irrigation Upgrade
Size: 1 Inch
The Rain Bird DASASVF100 Professional Anti-Siphon Valve is a solid, well-built option for residential irrigation systems. The 1-inch size makes it a great choice for larger irrigation zones where you want dependable water flow and reliable valve performance. The professional-grade construction feels durable and made to handle regular outdoor use. It’s reassuring to have a quality valve in an irrigation system, especially when it will be exposed to repeated watering cycles and outdoor conditions. The anti-siphon design is another important feature. It helps prevent irrigation water from flowing backward into the potable water supply, adding an extra level of protection to the overall system. Installation is straightforward when replacing a compatible existing valve, and the design makes it a practical choice for irrigation repairs, upgrades, or new sprinkler installations. I also appreciate that Rain Bird is a well-known name in irrigation equipment. Having a replacement part from an established brand gives me more confidence in its long-term reliability than some generic alternatives. Overall, the Rain Bird 1-inch Professional Anti-Siphon Valve is sturdy, dependable, and well designed. It’s a great choice for anyone maintaining or upgrading a residential sprinkler or irrigation system. ⭐⭐⭐⭐⭐ ... show more

Decent Valves
Size: 1 Inch
The house I purchased a couple years ago had these installed (5 of them). I don't know how old they were, but pretty much all were leaking, all in different places. I took a couple of them apart and there didn't seem to be any way to fix the leaks coming from the flow control knob, which is where several leaked from. You can buy replacement diaphragms, but that would't have solved the problem. So they don't last forever and can't be easily repaired unless it's a diaphragm problem. That said, I ordered and installed all new ones. USE THREADED UNIONS ON ALL CONNECTIONS. I read that in a review somewhere and it's extremely important. It makes installation so much easier and will enable you to easily change out the valves if you need to (which you will eventually), as opposed to cutting and rebuilding the PVC pipe you're attaching it to. It will cost you a little more to buy all of those unions, but it's totally worth it. It seems like they should have designed the valves to be easier to get on and off (there should be a built-in way to screw the valve onto the pipes as opposed to having to screw the pipes into the valve- built in unions). I installed the new valves and they all seem to work as they should, no leaks. They all run from my control panel just fine. I dinged the star off for the durability and the design shortcoming that makes installation more difficult than it really should be unless you separately buy unions. ... show more

Quality Product-Works Great!
Size: 1 Inch
Works great. Installed as a replacement on my irrigation manifold to replace a leaking valve. Installation was fairly easy, but had to cut out the old valve to install the new one. Note-if you're replacing the exact same valve, you can use the existing bodies on the old valve and just insert the new inner valve components-much quicker. Numerous YouTube videos on how to do this. Overall, I like Rainbird irrigation products and highly recommend this product. ... show more
