How Cold Is Too Cold for Sprinklers?

Now that the weather is finally starting to warm up, you might be wondering when it’s alright to start cultivating your lawn again. While you may be eager to get your lawn back to its pristine green state, it is important to remember that temperatures of 32 degrees Fahrenheit or lower put your sprinkler system at risk of freezing. That can cause cracking in exposed pipes or a build-up of pressure in the head of the sprinkler which can lead to a lot of issues you don’t want to deal with. Here are the 3 most important steps you can take to protect a sprinkler system from Mother Nature’s random freezes.

Shut Off the Water Supply

To protect a sprinkler system from the random chills that sometimes fall as we transition to spring, it’s important to shut off the water supply to the irrigation system by engaging the shut-off valve to the sprinkler’s irrigation system. This valve is generally located near the main water meter. It will be recognizable because of its orange and spring green tag.

Unplug the Booster Pump

If you have a booster pump, you also need to unplug that. The booster pump will be located on the ground and will be recognizable because of a cord going to an outlet box. Simply unplug it from the wall outlet or from the box.

Run The System

Lastly, you will want to relieve pressure by running the system. To run the system, turn on any zone from the sprinkler controller/timer for two minutes. Even if no water comes out of the irrigation system, the pressure in the mainline will still be released, which will protect it from developing tears or bursting if it should happen to freeze. Once you have completed this step, unplug the controller and timer.
