A well-maintained Calgary sprinkler system can last 20-30 years — but individual components fail at different rates, and Calgary’s freeze-thaw cycles accelerate wear on older systems. This guide tells you how long each component typically lasts and when to repair vs replace.
Calgary Irrigation System Component Lifespan
| Component | Typical Calgary Lifespan | Failure Signs | Replacement Cost |
|---|---|---|---|
| Poly pipe (main lines) | 25-40 years | Wet spots when system off | $150-$400 per break |
| Zone valves | 15-20 years | Zone stays on or won't activate | $80-$180 per valve |
| Spray heads | 10-15 years (Calgary freeze cycles) | Won't pop up, clogged, cracked body | $40-$80 per head |
| Backflow preventer | 10-15 years | Dripping relief valve, failed test | $250-$450 |
| Controller (basic timer) | 10-15 years | Display errors, zones won't program | $80-$150 basic, $220-$380 smart |
| Smart controller (Rachio/Hydrawise) | 10-15 years | App connectivity loss, zone failures | $220-$380 installed |
Should I repair or replace my 20-year-old Calgary irrigation system?
If the pipes are still intact and the valve manifold is functional, a 20-year-old Calgary system can often be refurbished for $1,500-$3,500 (new heads, rebuilt valves, new smart controller) instead of a full $6,000-$10,000 replacement. J.G. Irrigation provides an honest written assessment: which components to keep, which to replace, and projected cost for each option. Call 587-433-4795.
