A leaking irrigation system in Calgary wastes water, increases your water bill, and can damage your lawn by overwatering specific zones. Fortunately, most irrigation leaks can be located with a systematic inspection approach. This guide walks you through how to find and identify irrigation leaks — and when to call J.G. Irrigation for professional diagnosis.
Common Calgary Irrigation Leak Signs and Locations
| Symptom | Likely Cause | Repair Cost |
|---|---|---|
| Wet patch in lawn when system is off | Zone valve not closing (debris in diaphragm) | $75-$150 valve clean/replace |
| One zone loses pressure mid-cycle | Cracked lateral line or head casing | $100-$300 dig + patch |
| Water bubbling up at head location | Cracked head body or broken riser | $25-$75 head replacement |
| Unusually high water bill in summer | Zone valve stuck open or mainline leak | $150-$500 diagnosis + repair |
| Water running to street after system off | Low-head drainage — heads at low points draining after cycle | $15-$40 per head (check valve retrofit) |
How to Test Your System for Leaks — Calgary Method
Turn each zone on individually for 2-3 minutes. Walk the zone perimeter and look for: streams instead of sprays, heads that don't pop up fully, wet depressions in lawn (water pooling underground), and geysers at head locations. Mark each problem with a flag. Call J.G. Irrigation at 587-433-4795 with your findings — we often diagnose over the phone before dispatching a technician, saving you a service call fee.
