Winter Irrigation Blowouts
Protect your investment. Professional winterization using commercial-grade air compression to prevent frost damage to your irrigation system.
Don't Let Frost Destroy Your System
Vancouver Island may have mild winters compared to the rest of Canada, but our overnight temperatures regularly dip below freezing — and that's all it takes. Water left in your irrigation lines expands when it freezes, cracking pipes, damaging valve internals, and splitting fittings. The repairs can cost hundreds or thousands of dollars.
A professional winter blowout is the simplest, most effective way to prevent all of this. We use high-power commercial-grade air compressors to push every drop of water out of your system — from the mainline and lateral pipes to individual heads and backflow preventers. When the frost comes, there's nothing left to freeze.
How It Works
Connect
We connect our commercial air compressor to your system's blowout port or backflow preventer.
Purge
Each zone is individually blown out until no water remains — lines, valves, and heads are all cleared.
Shut Down
Your controller is set to off, the main valve is closed, and your system is safely winterized until spring.
Frequently Asked Questions
Why do I need a winter blowout on Vancouver Island?
Even though our winters are milder than the rest of Canada, Vancouver Island regularly sees overnight freezing temperatures. Water left in underground pipes can freeze, expand, and crack lines — leading to costly spring repairs. A blowout prevents this entirely.
When should I schedule my winter blowout?
We recommend scheduling between mid-October and mid-November, before the first hard frost. We monitor weather patterns and will advise you on timing.
What equipment do you use?
We use commercial-grade air compressors rated for irrigation systems. This ensures proper air pressure to clear every line without damaging components — something consumer-grade compressors can't guarantee.
Can I just drain the system myself?
Manual draining misses water trapped in low points, valves, and backflow preventers. A professional blowout with compressed air is the only way to ensure complete water removal from the entire system.
