From $65, up to six zones
Sprinkler blowouts in fall, start-ups in spring
Every zone cleared with compressed air before the first hard freeze, and turned back on and checked in spring. From $65 for up to six zones.
Water left in the lines freezes, expands and splits pipes, fittings and backflow valves. Pressurized irrigation districts shut the water off in October, but that doesn't empty your system — the water already in the pipes stays there. A blowout clears it with compressed air, zone by zone, so there's nothing left to freeze.
Book a blowout for after your irrigation district shuts the water off, and before the first hard freeze. Here that's usually mid-October into early November. The calendar fills fast once the first cold snap hits the forecast, so it's worth booking in September.
In spring we do the reverse: charge the system slowly so the pressure doesn't crack anything, run every zone, fix what winter broke, and set the controller for the season.
FAQ
Sprinkler Start-Up & Blowout: common questions
When should I blow out my sprinklers in Boise?
After your irrigation water is shut off and before the first hard freeze — usually mid-October into early November in the Treasure Valley. If a hard freeze is forecast before we get to you, a manual drain of the backflow buys a few days.
How much does a sprinkler blowout cost?
$65 for systems up to six zones, plus $6 for each zone after that. Most subdivision homes have six to eight zones.
Do I need a blowout if my irrigation district shuts the water off?
Yes. Shutting off the supply stops new water coming in, but the lines are still full. That's the water that freezes.
