Your customers who use the same water source for things other than irrigation will benefit from an anti-siphon valve. They are designed to let water freely flow in one direction but automatically close if they sense pressure in the opposite direction. This prevents dirty water from backflowing into the source. Since anti-siphon valves must be installed above ground, they are also much easier for technicians to access if there’s a problem.

If you need an irrigation anti-siphon valve for an installation or replacement project, you can get the correct part from SiteOne Landscape Supply. We have electric backflow prevention valves from all major brands, including Superior, Hunter, Rain Bird, Irritrol and Flomatic. Glass-filled nylon and PVC valves are great for residential work while a brass anti-siphon valve offers durability for heavy commercial and industrial applications. Order a 3/4” or 1” anti-siphon valve with multiple connection types. We also provide knowledgeable service from fellow irrigation professionals so you can do the same for clients.
