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

  • Fit perfectly
Size: 1 Inch
I purchased this to replace a 23-year-old valve that I initially thought had failed. To my surprise—and relief—it fit perfectly with the original base that’s been in place for over two decades. Later, I discovered the old valve still worked, but I’m glad to have a fresh replacement on hand. This new valve is a true drop-in solution, requiring no modifications. One thing I noticed right away was the sound—it was noticeably louder at first. However, it’s quieted down over time, likely just needing a bit of break-in. Overall, I’m hopeful this new valve will prove just as durable as the original. ... show more
