Kettle Valley Irrigation Blowout Quotes
Draining a system does not empty it. Low points and laterals hold water whatever the grade, which is why compressed air is the only reliable way to clear a system.
Slope changes how a blowout has to be sequenced. Water collects at the bottom of every zone, so clearing has to work with the grade — and the low points that hold water are exactly where freeze damage does the most expensive harm.
Commonly requested here
Winterization work on Kettle Valley properties
- Sequencing zones so low points on the slope clear fully
- Extra attention to the lowest heads and fittings in each zone
- Verifying check valves are not trapping water in laterals
- Clearing terraced drip zones alongside turf zones
- Draining assemblies at the bottom of the property
Worth knowing
Check valves that prevent low-head drainage during the season also trap water at blowout time. On slope systems they need accounting for explicitly, or they hold water through the winter exactly where it will do damage.
Issues that come up in Kettle Valley
- Narrow side yards and boulevards needing strip nozzles rather than standard arcs
- Builder-installed systems never tuned after the landscaping matured
- Bench elevation requiring pressure regulation across sloped zones
Local context
- Kettle Valley is a planned community on the Upper Mission bench, named for the historic Kettle Valley Railway, with a notably walkable and compact layout.
- Lots are generally smaller and more uniform than in surrounding Upper Mission, and most systems date from the original build.
- Turf areas tend to be defined and modest, with ornamental beds making up a significant share of planting.
Bench elevation brings warmer afternoons and more exposure than the flats below, while compact lots mean small errors in nozzle choice waste a visible share of the water.
What to expect
Typically part of the job
- Extra attention to the lowest heads and fittings in each zone
- Sequencing zones so low points on the slope clear fully
- Draining assemblies at the bottom of the property
- Note of any faults observed for spring follow-up
- Controller shut down or set to seasonal off
- Draining of any pump, pressure tank and filtration

Questions
Winterization in Kettle Valley
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.
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.
What does an irrigation blowout cost in the Okanagan?
We do not publish prices, because the work is quoted by independent contractors and the number depends on the property. The things that move it most are the number of zones, the length of mainline, whether there is a pump, filtration or an above-ground backflow assembly to drain, how accessible the blowout port and valve boxes are, and how late in the season you book. Requesting two or three quotes is the reliable way to find out what your system should cost, which is what this service is for.
What is an irrigation blowout?
An irrigation blowout is the process of forcing compressed air through an irrigation system to push out every bit of water left in the pipes, valves and sprinkler heads before winter. A contractor shuts off and isolates the water supply, connects a compressor at the blowout port, then opens each zone in turn until only air and mist come out of the heads. It is done because water expands as it freezes, and buried pipe is the most expensive possible place to discover that.
