The purpose of an anti-siphon valve is to dump residual line water and prevent it from entering your water supply. Anti-siphon valves should be installed above the highest point in the system. Installing the valve below supply lines and spray heads will cause residual water to flow back to the valve and released through the cap. The amount of backflow is not caused by the valve.

Rated 5.0 out of 5.0 by 3/4 in. 150 psi Anti-Siphon Valve with Flow Control I have 20yr old lawn genie values - this is a direct replacement. Some of the new valves the inlet and outlets are ~ 3/8 of inch further apart - this valve works with out redoing the present plumbing. August 16, 2016
Rated 1.0 out of 5.0 by unreliable valve repeatedly stuck open in the middle of the night , wasting water April 7, 2016
Rated 5.0 out of 5.0 by Yes! Home Depot Carried it!!! Exact replacement valve for my Lawn Genie in ground sprinkler system. Was very happy I did not have to go farther than Home Depot on line to find this part. August 26, 2014
Rated 4.0 out of 5.0 by This valve is good, old green one bad This valve is replacing the older Green Lawn Genie valve that broke off just above the input line boss. Wasted 2000 CF of water. Valve in protected area, no sun and never froze. Recommend changing all old green valves. A second one broke but not as bad. The plastic cracked allowing the valve to turn on. January 24, 2012
Rated 5.0 out of 5.0 by Decent Valves I bought these as replacements for the same one that were 5+ years old. One developed a pin hole leak in the cap. We have squirrels. These guys do the job. December 9, 2015

Rated 5.0 out of 5.0 by Great assembly for effective replacement parts The value, pricing, delivery and quality were great. I have encorporated elements of the assembly into my existing system and everything works well. I have contacted the vendor customer support on adjustment issues and they were very helpful. I need this particular part to repair my exisiting hard line assemblies. June 16, 2015
Rated 1.0 out of 5.0 by AVOID. NOT DURABLE. I purchased in-store the green plastic version of this valve. Although it is rated at 150 psi, it blew itself apart with 50 psi after three months. Yes, it is under warranty, but it will take me several hours to replace it plus some PVC parts. I just bought a brass Champion Arrowhead valve on Amazon to replace it. Yes, it cost more, but my time is worth something to me. Home Depot, how about finding new vendors that can produce decent stuff. Much of the plastic used for your irrigation items is junk that lasts a short time. I may migrate entirely to Amazon. July 14, 2014
