Irrigation winterization in King County

Get the water out before the first freeze.

We blow out residential sprinkler systems with compressed air, zone by zone, so there's nothing left in the lines to freeze and crack over winter.

Water left in the lines doesn't stay water.

Irrigation pipes run shallow, just under the lawn. On the first hard freeze, whatever water is still inside them turns to ice. Here's what that does to a system.

  1. 145°F

    The lines are still full

    When the season ends, water sits in pipes, valves and sprinkler heads.

  2. 232°F

    An overnight freeze

    Ice starts forming along the pipe walls and works its way inward.

  3. 328°F

    Ice needs more room

    Frozen water takes up about 9% more space than liquid water, and it pushes outward.

  4. 4Spring

    Cracks show up at startup

    Split pipes, cracked valves and broken heads usually aren't found until you turn the system back on.

A blowout pushes that water out with compressed air, so by the time it freezes there's nothing left inside to expand.

A zone is a group of sprinkler heads that runs together. Your sprinkler controller usually shows how many you have.
