Protect underground sprinkler lines from freeze damage before winter hits the Wenatchee Valley. Fast, thorough blowouts that clear every zone.
A sprinkler blowout clears water from your irrigation lines, valves and heads using compressed air, so nothing is left behind to freeze and expand once Wenatchee Valley temperatures drop for the season. Most homeowners in the valley schedule their blowout sometime in fall, before sustained freezing weather sets in — the exact week varies year to year, which is why we work through the valley zone by zone rather than waiting for a single fixed date.
Underground sprinkler lines, valves, backflow devices and heads hold water even after the system is shut off for the season. Wenatchee Valley winters bring sustained freezing temperatures, and water left in those components can freeze and expand.
A seasonal blowout is intended to help reduce that risk by clearing the water out before hard freezes arrive, rather than leaving it to chance.
We isolate the irrigation system from the water supply, then use compressed air to push through each zone in sequence, clearing water from the mainline, lateral pipes, valves and every sprinkler head.
Backflow devices and above-ground components get particular attention since they're the most exposed to freeze damage. This is a service call, not a DIY procedure — the wrong air pressure or sequence can damage a system, which is why it's handled by a technician rather than a homeowner with a compressor.
Mainlines and lateral pipes, control valves and valve boxes, backflow prevention devices, and the sprinkler heads themselves can all retain water after the system shuts off. Low points in the pipe run are particularly prone to holding standing water, which is why a thorough blowout works through every zone rather than just the visible heads.
Most Wenatchee Valley property owners schedule their blowout in fall, as overnight temperatures start dropping consistently and before the first sustained hard freeze. Because that timing shifts year to year, we open scheduling early in the season and work through the valley in the weeks leading up to winter.
A technician arrives, confirms the number of zones and system layout, shuts off the water supply, and connects compressed air to clear each zone in sequence. We check backflow devices and above-ground components before we leave.
Every visit is a real on-site service call — we don't quote sprinkler winterization sight unseen.
A blowout is intended to clear water from an irrigation system before freezing weather, reducing the risk of freeze-related damage to pipes, valves and heads. It is not a repair service — if a system already has a leak, a broken head, or a failing valve, that issue should be addressed separately. We don't make guarantees about specific freeze temperatures or claim a blowout eliminates all risk of winter damage; we do the work thoroughly and tell you honestly what we find along the way.
As fall progresses toward sustained freezing temperatures. We work through the valley zone by zone, so scheduling before the first hard freeze gives you the most flexibility.
Water left in pipes, valves and heads can freeze and expand once temperatures drop, which can stress or damage those components over winter.
A technician uses compressed air to push remaining water out of the irrigation lines, valves and sprinkler heads so the system sits empty through winter.
Water expands as it freezes, which can stress pipes, fittings, valves and backflow devices. A proper blowout helps reduce that risk before sustained freezing conditions arrive.
Yes. New installs, repairs, and controller upgrades are handled separately from seasonal winterization — see our irrigation systems page for details.
