When clients are using the same water source for irrigation and in-home use, you need a way to prevent them from mixing. A manual anti-siphon valve contains a backflow preventer so the dirty irrigation water doesn’t end up in a client’s drinking and bathing water. By design, anti-siphon valves are a user-friendly option that’s easy to maintain. They are the best choice for small landscapes and gardens that need a reliable way to separate water systems.

Shop at SiteOne Landscape Supply if your business needs irrigation anti-siphon valves for residential and commercial customers. We have durable brass sprinkler anti-siphon valve components in standard connection sizes such as 3/4-inch and 1-inch valves. They’re made by industry leaders such as Champion, Aqualine, Superior and K-Rain.

If you have questions or don’t see the anti-siphoning valve that’s best for a job, get in touch. Our knowledgeable professionals are happy to assist you by phone or email, and you can also visit a local SiteOne branch to chat in person.
