Sprinkler Blowout & Winterization
Sprinkler Blowout &
Utah’s freeze-thaw cycles are hard on irrigation systems. Even a small amount of water left in your pipes, valves, or backflow preventer can freeze, expand, and crack components, turning into an expensive repair bill next spring. Lawn Doctor of Utah County & Heber Valley clears every zone of your system with professional compressed-air equipment, so your sprinklers are protected all winter and ready to go the moment the weather turns.
Why Winterization Matters
Water expands roughly 9% when it freezes. Left inside your irrigation lines, that expansion cracks PVC pipe, splits sprinkler heads, and damages backflow preventers and valves, damage you usually don’t discover until you turn the system back on in spring. A proper blowout removes that risk entirely by clearing every drop of water from the system before temperatures drop.
Our Blowout Process
Shut down and drain the main water supply to the irrigation system
Connect a professional-grade air compressor and clear each zone individually, from closest to farthest
Run each zone in short cycles to fully purge water without overheating components or over-pressurizing pipe and heads
Drain and protect the backflow preventer, the part most vulnerable to freeze damage
Inspect for leaks, broken heads, or valve issues while the system is off, so small problems don’t turn into spring surprises
We calibrate air pressure to your system’s pipe material and zone layout, enough to fully clear the lines without the cracked pipes and blown-out heads that come from a rushed, one-size-fits-all blowout.
When to Schedule in Utah County
Utah County’s first hard freeze typically arrives between mid-October and late October. We recommend scheduling your blowout by early-to-mid October, before nighttime temperatures start dropping into the high 30s. Waiting until the first freeze is already forecast is a gamble, it only takes one hard freeze to damage a system that wasn’t winterized in time.

Frequently Asked Questions
Does Lawn Doctor do sprinkler blowouts in Utah County?
Yes. Lawn Doctor of Utah County & Heber Valley offers professional sprinkler blowout and winterization services, clearing irrigation systems of water before winter freezes to prevent pipe, valve, and backflow damage.
When should I winterize my sprinkler system in Utah?
In Utah County and the Heber Valley, the first hard freeze typically hits between mid-October and late October. Sprinkler systems should be blown out by early-to-mid October, before nighttime temperatures consistently drop into the high 30s.
What happens if I don’t winterize my sprinklers?
Water left in irrigation pipes expands as it freezes, which can crack PVC pipe, damage sprinkler heads, and destroy backflow preventers and valves, damage that’s often not discovered until the system is turned on in spring.
How does a professional sprinkler blowout work?
A technician shuts off the water supply, then uses a professional air compressor to clear each irrigation zone individually in short cycles, fully purging water while avoiding the pressure levels that can crack pipe or blow out heads. The backflow preventer is drained and protected as the final step.
Is a professional blowout better than doing it myself?
DIY blowouts done with the wrong compressor (too much CFM or PSI for your pipe and head material) are one of the most common causes of freeze-season irrigation damage. A professional calibrates pressure to your specific system.
