Every May in Calgary, irrigation companies get flooded with repair calls from homeowners who turned on their own systems incorrectly and caused damage that could have been avoided. This guide covers the most dangerous spring startup mistakes Calgary homeowners make — and exactly what to do instead.
Top 7 Spring Sprinkler Startup Mistakes in Calgary
| Mistake | Why It's Dangerous | Cost of Getting It Wrong |
|---|---|---|
| Opening backflow preventer too fast | Water hammer cracks internal check valves — destroys BFP | $250-$600 BFP replacement |
| Starting system before late April | Calgary overnight frost in April can refreeze a system that was just started | Full repeat of freeze damage |
| Not walking each zone at startup | Winter damage or pest damage to heads goes unnoticed; dry spots or flooding result | $200-$500+ undetected leaks |
| Setting July schedule in May | Over-watering in spring creates fungal lawn disease | $200-$1,000 lawn disease treatment |
| Skipping controller battery/power check | Dead battery = all programming lost; system runs all zones or doesn't run at all | Hours of wasted water; dried lawn |
The safest approach is to have J.G. Irrigation perform your spring startup — a professional takes 45-75 minutes to open, inspect, and program the system correctly, identifying any winter damage before it becomes an expensive problem. The $80-$130 startup cost is insurance against a $500-$2,000 repair bill. Call 587-433-4795 to book your May 2026 startup now.
Can I do my own spring irrigation startup in Calgary?
You can do a basic startup yourself if you know the location of your backflow preventer, know how to open it slowly (¼ turn per 30 seconds), and walk each zone to inspect heads. However, without a pressure gauge and zone-by-zone testing, you may miss underground leaks, cracked valves, or damaged BFP check valves. J.G. Irrigation's $80-$130 startup includes all of these checks. Call 587-433-4795.
