Winterization – Protect Your Irrigation System from Freezing Damage
Although Vancouver Island enjoys a relatively mild climate, cold snaps can still freeze water in your irrigation system. When water freezes, it expands and increases in volume by roughly 9%. That expansion is powerful enough to crack pipes, split sprinkler heads, burst valves and rupture pumps. Because most irrigation pipes are buried only 8–12 inches below the surface, they are particularly vulnerable to freeze damage. The only way to guarantee they survive winter is to remove all the water before temperatures drop.
Why Winterization Matters
Prevent costly repairs – Replacing cracked pipes, broken manifolds or damaged backflow preventers can be expensive and messy. Expelling the water in autumn saves you from major repairs in spring.
Protect your backflow device – Freezing water can damage the internal components of a backflow preventer. Winterizing ensures this vital device continues to keep contaminants out of your drinking water.
Peace of mind – You won’t be worrying about hidden leaks or a yard torn apart to repair burst pipes when you should be enjoying your garden.
