Sprinkler Blowout & Winterization in Southwest Michigan
Water left in sprinkler lines freezes, expands and cracks pipes, valves and backflow devices. That damage is expensive and does not show up until spring. AAA Power Washers & Deck Restorations provides sprinkler blowouts in St. Joseph, Benton Harbor, Stevensville, South Haven, Kalamazoo and across Southwest Michigan.
Our Blowout Process
- Shut off the water supply to the system
- Connect a commercial air compressor at the proper, safe pressure
- Blow out each zone, one at a time, until only mist comes out
- Drain and protect the backflow preventer
- Set the controller to off or rain mode for winter
When to Schedule a Sprinkler Blowout
Book your blowout from late September through early November, before the first hard freeze. In Southwest Michigan, overnight lows can drop below freezing in October, so earlier is safer. Pair it with fall cleanup and gutter cleaning.

Sprinkler Blowout Southwest Michigan: Common Questions
Can I just drain the system?
Draining often leaves water in low spots. Blowing out with compressed air is the most reliable method in Michigan.
Do I need to be home?
No, as long as we can access the shut-off valve and the controller.
Do you blow out drip lines?
Yes, at a lower pressure.
