Atmospheric breaker (aka anti-siphon)

Do you have one of these? If so… you probably shouldn’t!


That device you see sticking up from the ground is an atmospheric breaker (also known as an anti-siphon device). It was designed to keep your drinking water safe from cross-contamination with your sprinkler system when the water isn’t running.


Here’s the catch:

  • These setups are old-fashioned and may not be up to current code.

  • Age and exposure often mean they no longer work properly.

  • They’re very prone to freezing and shattering in cold weather.

  • Their height makes them easy to break off by accident.


The better solution:

Replace it with a modern, up-to-code backflow valve installed in a service box below soil level. Not only does this protect your drinking water, but it also keeps your sprinkler system safe, secure, and weather-resistant.


If you think you may have one of these outdated devices, give us a call. Our team can inspect your system and upgrade it for safety and peace of mind.
