| Jul 14, 2021 at 1:25 | comment | added | jsotola | @GeorgeAnderson you are correct about them also being called anti siphon valves ... they do prevent backflow ... like you said, there is also a backflow preventer valve that is a one-way valve and is installed inline with the water supply ... such valves have a springloaded mechanism that closes when the city side pressure drops | |

| Jul 14, 2021 at 0:04 | comment | added | George Anderson | I disagree, those look like anti siphon valves. jsotola, that may be just a different name for vacuum breakers, didn't mean to contradict you. :) A properly installed irrigation system would have a double check valve to prevent backflow. The actual electrically controlled valves could be anywhere, I've even seen some installed in crawl spaces. Again, like jsotola said, look for in ground boxes (usually a green cover)...unfortunately they sometimes can get completely overgrown by grass or covered with bark and are hard to find. | |
