$129 sprinkler blowouts

- Backflow cleared, controller set for winter
- You don't need to be home
What your blowout costs
Quick answer: $129 covers any system with up to 8 zones. Each zone after that adds $15. That's the whole price for the blowout.
Not sure how many zones you have? Count the stations in use on your controller. Or we'll count them on site before we start.
Pay once, or have it handled every year
One blowout, booked when you want it. You'll need to remember to book again next fall, and the spring startup is separate.
Booked full for 2026Your fall blowout and spring startup are included and scheduled for you. No remembering, no racing the October rush.

Fall 2026 is full. We run blowouts from late September through early November. The last two weeks of October fill first, because that's when everyone remembers. If you care which day we come, book now.
A light frost won't hurt buried lines. A multi-day hard freeze will. The goal is to have every system clear before the ground starts freezing in November. Earlier than late September and you're giving up weeks of watering you may still want.
What we do on site
- Shut off the water supply and isolate the backflow assembly
- Connect a 110 CFM commercial compressor at the right point on your system
- Blow each zone on its own until the heads run dry, not one pass across the whole yard
- Cycle the backflow valves so nothing is left holding water
- Set your controller to off or rain mode for the season
- Note anything that will need attention at spring startup
That last step matters more than people expect. Fall is when we spot the problems worth fixing before winter, not after it. If we find something, we tell you and quote it. We don't do extra work without your OK.
Why a blowout matters in Minnesota
Minnesota doesn't freeze gently. The ground freezes deep, and it freezes and thaws again and again. Water trapped in a line expands about nine percent when it turns to ice. It has nowhere to go, so it splits the pipe, cracks the head, or tears the valve diaphragm.
You rarely see that damage in the fall. It shows up in spring, when a zone won't build pressure or water bubbles up in the middle of the lawn. A mainline break found in May costs several times what the blowout would have.
Why DIY usually isn't enough
The first problem is volume. Clearing a residential zone takes roughly 80 to 120 CFM of airflow. A typical garage compressor puts out 10 to 15. It'll make noise and push some water, but it won't clear the lines.
The second is pressure. Too much pressure through a dry system damages the parts you're trying to protect, like rotor gears and valve diaphragms. A proper blowout is high volume at controlled pressure, one zone at a time. At $129, it's rarely worth the risk to do it yourself.
Blowout questions
How much does a sprinkler blowout cost?
$129 for up to 8 zones, plus $15 for each zone after that. A 10-zone system is $159. Members get their blowout included with the $215/year membership.
When should I winterize my sprinkler system in Minnesota?
Late September through early November, before the ground starts to freeze. The last two weeks of October fill up fastest, so book early if the date matters to you.
Do I need to be home?
Usually not, as long as we can reach the water shutoff, the backflow assembly, and the controller. We'll confirm access when you book.
Can I blow out my own sprinkler system?
Usually not well. A residential zone needs roughly 80 to 120 CFM of airflow, and a typical homeowner compressor delivers 10 to 15. Too much pressure can also damage rotor gears and valve diaphragms.
What happens if I skip the blowout?
Water left in the lines freezes and expands. That can crack heads, split valves, damage the backflow assembly, and break buried lines. The damage usually shows up at spring startup and costs far more than the blowout.
Is the blowout included in the membership?
Yes. The $215/year membership covers your fall blowout and your spring startup, scheduled for you each year.
