As the crisp autumn air settles over Port Coquitlam, Port Moody, and Coquitlam, it’s a beautiful time of year. But with those changing colours comes the inevitable reality of colder weather and, eventually, frost. For homeowners with an in-ground irrigation system, this is a critical time to act. Leaving water in your sprinkler lines over the winter can lead to serious damage, turning a simple maintenance task into a costly irrigation system repair in Port Coquitlam.
Understanding why and how to properly winterize your sprinkler system is the first step to protect your investment.
Why Winterization is a Must-Do in the Tri-Cities
The science behind winterization is simple: water expands when it freezes. Your irrigation pipes are made to handle water pressure, but they are not built to withstand the force of ice expanding inside them. This expansion can crack or split pipes, damage sprinkler heads, and even ruin the crucial backflow prevention device.
The Tri-Cities area, while milder than some parts of Canada, still experiences freezing temperatures. A single overnight frost is enough to cause damage if your system isn’t properly prepared. The last thing you want is to turn on your system next spring, only to discover a hidden leak that’s flooding your lawn or, even worse, not having water pressure at all due to a burst mainline. This is why irrigation system maintenance in Port Moody and the surrounding areas is so important.

The Risks of DIY Winterization
Many homeowners consider doing the winterization themselves. While the idea of a DIY project is appealing, it carries significant risks. Simply draining the water from the main valve isn’t enough. Water will remain trapped in the low points of the pipes, sprinkler heads, and other components.
Using a small air compressor to blow out the lines can also be dangerous. If the pressure is too high, it can shatter pipes or blow out sprinkler heads, leading to expensive repairs. Without the right equipment and experience, you could be setting yourself up for a major sprinkler system repair in Coquitlam come spring. A
professional service uses specialized, high-volume air compressors that push the water out efficiently and safely, without risking damage.
The Professional Winterization Process
A professional service provides peace of mind and ensures the job is done right. At Select Sprinklers, our winterization process is designed to protect every part of your system from frost damage.
1. System Shut-Down: We start by turning off the water supply to your irrigation system and draining the main valve. This is the first and most critical step.
2. Backflow Device Care: Your backflow prevention device is a crucial part of your system. It’s also one of the most vulnerable to freezing. We carefully shut off, drain, and protect this device to prevent cracks.
3. The “Blow-Out”: Using a powerful air compressor, our technicians connect to your system and blow out the water from all the lines, zone by zone. We use the correct pressure and technique to ensure all water is removed without damaging your pipes or components. This process can be slow and requires patience to do correctly.
4. Controller Adjustment: Finally, we turn off your system’s controller for the winter to prevent it from accidentally turning on. We’ll leave your system in a safe state, ready for its spring start-up.
Investing in professional winterization is far more cost-effective than dealing with burst pipes and costly repairs.
