Sprinkler Winterization
Protect your irrigation system from winter freeze damage.
Why Winterization Matters
While Seattle's winters are milder than many parts of the country, we still experience freezing temperatures that can cause serious damage to irrigation systems. Water left in pipes, valves, and sprinkler heads can freeze and expand, cracking pipes and destroying components.
A single freeze event can cause hundreds or even thousands of dollars in damage. Professional winterization is a small investment that protects your entire irrigation system and saves you from costly spring repairs.
Best time to winterize: before the first freeze, typically October through November. Don't wait until temperatures drop -- by then, the damage may already be done.
Our Winterization Process
System Shutdown
We shut off the water supply to the irrigation system and turn off the controller.
Drain the System
We open drain valves and manual drains to remove as much water as possible from the lines.
Blow Out Lines
Using a professional air compressor, we blow compressed air through every zone to remove all remaining water from pipes and heads.
Insulate Backflow Preventer
We insulate exposed backflow preventers and above-ground components to protect from freezing temperatures.
