Winterize irrigation system
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.
