Sprinkler Winterization & Blowouts in Surrey & Metro Vancouver
Protect your pipes before the first frost hits.
In Metro Vancouver, our winters can be unpredictable. While we enjoy a mild climate, a single deep freeze can turn the water left in your irrigation lines into ice. When water freezes, it expands, causing underground pipes to crack, valves to shatter, and backflow preventers to fail.
At Hudson Irrigation and Lighting, we provide professional Irrigation Winterization (also known as a Blowout) to ensure your system is completely cleared of water and protected until spring.
Why a Professional Blowout is Essential
Many homeowners try to drain their systems manually, but gravity isn’t enough to remove all the water from low points in the lines. Our team uses high-volume industrial air compressors to “blow out” every drop.
The Benefits of Professional Service:
- Prevent Costly Repairs: Replacing a cracked backflow assembly or digging up a burst mainline can cost thousands.
- IIABC Certified Standards: We follow strict industry protocols to ensure we don't damage your delicate valves with too much air pressure.
- Peace of Mind: We guarantee your system is 100% clear before we leave your property.
Our Winterization Process: Step-by-Step
We take the “guesswork” out of fall maintenance. Our technicians perform a thorough shutdown:
| Step | Action | Why it Matters |
| 1. Water Shut-off | We locate and turn off the main irrigation water supply. | Stops new water from entering the system. |
| 2. Compressor Hookup | We attach a high-volume compressor to the blowout port. | Ensures we have enough air volume to clear the entire line. |
| 3. Zone Cycling | We run through every zone, blowing air until only mist remains. | Clears the “low spots” where water usually collects and freezes. |
| 4. Drain the Backflow | We open the test cocks on your backflow preventer. | Protects the most expensive component of your system. |
| 5. Controller Shutdown | We set your timer to “Off” or “Standby.” | Saves energy and prevents the system from “dry firing” in winter. |
