TORO anti-siphon valves provide the features and benefits of our popular jar top valves and atmospheric backflow preventer in one easy to install device. These valves are typically installed 6 to 12 in above the highest sprinkler making them easy to access and install. The threaded bonnet jar top system enables fast and easy servicing. TORO anti-siphon valves feature flow control making it possible to fine-tune the amount of water pressure going to each individual zone, reducing misting and fogging at the sprinkler and saving water.
