Big White Irrigation Blowout Quotes
At alpine elevation this is the service that matters most, and timing is nearly the whole discipline. Hard frost can arrive before the end of September, so a blowout scheduled on valley timing is already too late.
Winterization is the one seasonal service where being late is genuinely costly — and being early costs nothing at all. At Big White's elevation, irrigation is almost entirely a question of timing — which shapes what winterization work here usually involves.
Commonly requested here
Winterization work on Big White properties
- Scheduling well before the valley's usual blowout window
- Thorough clearing appropriate to severe freeze exposure
- Full draining of every above-ground component
- Service arranged for absentee and vacation owners
- Confirmation that nothing is left holding water
Worth knowing
At this elevation there is no meaningful late option. Once you have stopped watering, the correct time to blow out is immediately — waiting gains nothing and risks the entire system.
Issues that come up in Big White
- Late ground thaw delaying spring start-up well past valley timing
- Unexpected shoulder-season cold snaps threatening pressurised systems
- Absentee ownership meaning faults go unnoticed for long periods
Local context
- Big White Ski Resort sits at roughly 1,750 metres, dramatically higher than the Okanagan valley floor, with a correspondingly short frost-free season.
- Hard frost can arrive well before the end of September and snow can persist into late spring, compressing the service window at both ends.
- Most properties are vacation, chalet or strata holdings whose owners are frequently not on site.
At roughly 1,750 metres the frost-free season is dramatically shorter than the valley's; hard frost can arrive in September and snow can persist into late spring.
What to expect
Typically part of the job

- Note of any faults observed for spring follow-up
- Water supply shut off and isolated at the source

Questions
Winterization in Big White
When should an irrigation system be blown out?
Before the first hard frost, which in the Central Okanagan valley usually means sometime in October — earlier at elevation. Because being early has no downside once you have stopped watering and being late risks cracked pipe, the sensible approach is to book toward the early end of the window rather than waiting for cold weather to force the decision.
Is it too late to blow out my sprinklers?
By late October in the Central Okanagan you are running out of window — not because it is technically impossible, but because contractor availability collapses in the last week or two before hard frost. Valley-floor properties can typically still book through most of October in a normal year. Higher-elevation areas — Big White, Black Mountain, upper Glenrosa, Joe Rich — should have been done in September and are genuinely late by month-end. If overnight temperatures have already dipped below zero at your property, treat it as urgent: shut the irrigation supply off at the isolation valve immediately, then get a blowout booked before the next cold night. A blowout scheduled the day after a hard freeze is a repair conversation, not a winterization one.
How long does a sprinkler system blowout take?
For a straightforward residential system with four to six zones and an accessible blowout port, a blowout usually runs thirty to forty-five minutes. Larger properties — a dozen zones, a pump and pressure tank, filtration, a long mainline out to the far side of an acreage — can take two to three hours because there is simply more to clear and more to drain. Systems with poor blowout-port access, buried valve boxes that need locating, or above-ground assemblies that must be dismantled all add time. A contractor should be able to give you a reasonable duration over the phone once they know how many zones you have and whether there is a pump.
Can I just drain the system instead?
Draining alone is not sufficient on most systems. Even with drain valves and favourable grade, laterals and low points retain water that gravity will not remove, and it only takes a small amount in the wrong place to crack a fitting or a valve body. Compressed air is used because it clears water that draining leaves behind.
