Winterization & Blowouts
Sprinkler Winterization & Blowouts in Metro Detroit
Michigan winters are hard on irrigation systems. A professional blowout removes all water from your pipes and heads before the freeze — protecting your system from costly damage and keeping it ready for spring.
Our Process
How We Winterize Your Irrigation System
Our winterization process is thorough and systematic — every zone, every pipe, every component is properly purged and protected before the first freeze.
Controller Shutdown
Properly shut down your irrigation controller and disable all scheduled watering cycles.
Water Supply Shutoff
Close the main irrigation shutoff valve to stop water flow to the entire system.
Compressed Air Blowout
Use professional-grade compressed air to purge all remaining water from every zone and pipe.
Zone-by-Zone Purge
Systematically blow out each zone to ensure no water remains that could freeze and crack pipes.
Valve & Backflow Protection
Drain and protect valves, backflow preventers, and other components from freeze damage.
Final System Check
Confirm all zones have been properly purged and document the system condition for spring start-up.
Don't Skip Winterization
What Happens If You Skip the Blowout?
Water left in your irrigation pipes will freeze and expand when Michigan temperatures drop. The result is cracked pipes, burst fittings, and broken heads — repairs that cost far more than a simple winterization visit.
A professional blowout costs a fraction of what freeze damage repairs will run. Don't risk it — schedule your winterization before the first hard freeze.

Common Questions
Winterization FAQs
When should I winterize my sprinkler system in Michigan?
We recommend scheduling your blowout in October or early November — before the first hard freeze. Michigan temperatures can drop quickly, so don't wait until the last minute. Fall slots fill up fast.
What happens if I skip a sprinkler blowout?
Water left in your pipes and heads will freeze and expand when temperatures drop below 32°F. This causes cracked pipes, burst fittings, broken sprinkler heads, and damaged backflow preventers — repairs that can cost hundreds of dollars in the spring.
Why is compressed air used for winterization?
Compressed air is the most effective way to force all remaining water out of your irrigation pipes, heads, and valves. Gravity drainage alone leaves water in low spots and horizontal runs. A professional blowout ensures every section of the system is fully cleared.
How long does sprinkler winterization take?
Most residential systems take 30–60 minutes depending on the number of zones. We bring our own professional-grade compressor — you don't need to provide any equipment.
Can winterization prevent freeze damage?
Yes — a proper blowout is the single most effective thing you can do to protect your irrigation system from winter damage. It's a small investment that prevents much larger repair bills in the spring.
