Winterize irrigation system

Difficulty: call_a_proTime: 60 minsEst. Cost: $50 - $100

Why it matters

Water left in underground irrigation pipes will freeze, expand, and crack the pipes and spray heads. Fixing freeze damage can cost $500–3,000. A $50–100 professional blow-out prevents it entirely.

Stop forgetting to do this.

How to do it

  • 1

    Book an irrigation company in September or October before the first hard freeze in your area.

  • 2

    They'll use an air compressor to blow water out through each zone's sprinkler heads.

  • 3

    Turn off the controller and set to 'rain/off' mode for winter.

  • 4

    Close the main irrigation shutoff inside.
