Dos and Don’ts of Winterizing Your Sprinkler System

September 06, 2017

Winters in Minnesota get cold… like really cold. So cold that anything with water or moisture will freeze over, including the ground and irrigation pipes. When water freezes, it expands and can crack or burst the pipes that contain it. This can cause lots of damage for homeowners. Because of this risk, it is extremely important to blowout/drain the water from irrigation systems and shut off the water.

Frozen Irrigation


Don’t forget to turn off your water.

Don’t forget to call a professional for a sprinkler system winterization.

Don’t wait until the ground already begins to freeze to schedule an irrigation blowout.

Don’t gamble and think your pipes won’t freeze.

Don’t try to do it yourself without fully understanding the risks and process.

Not winterizing your sprinkler system can lead to:

  • Pipes cracking underground
  • Pipes freezing and bursting
  • Backflow preventer breaking

Trying to do it yourself can lead to:

  • Using the wrong size compressor
  • Pipes not fully being cleared of water
  • Too much pressure being forced through the system
  • Accidental injury
  • Missing a step or forgetting to turn off the water
