Sprinkler System Leak Detection Calgary: Finding and Fixing Underground Irrigation Leaks

Underground irrigation leaks in Calgary are common and often go undetected for weeks or months โ€” driving up water bills and killing lawn sections while homeowners assume it is a watering scheduling issue. J.G. Irrigation's IA-certified technicians diagnose underground leaks using pressure testing and zone-isolation methods. Most underground leaks are located and repaired on the same visit.

Signs You Have an Underground Irrigation Leak

  • Soggy patch in lawn that never dries: The most obvious sign โ€” water is pooling underground and saturating the soil above a pipe break. Calgary clay soil absorbs slowly, so saturation stays visible for days.
  • One zone showing noticeably lower pressure than others: A partial pipe break or fitting failure bleeds pressure before water reaches the zone heads โ€” heads that should pop to full height stay partially extended.
  • Calgary water bill significantly higher than previous summer: A 1/4-inch crack in a Calgary irrigation lateral can discharge 100-200 gallons per zone cycle โ€” a silent water cost that accumulates quickly over a season.
  • Zone runs full cycle but lawn section not getting water: Water is exiting at the break point rather than at the zone heads โ€” the zone appears to run normally from the controller but the heads are getting no pressure.
  • Sinkholes or ground depression forming: Pipe break with high flow has washed soil away underground โ€” the surface depression appears after several weeks of undetected leaking.

How J.G. Irrigation Detects Underground Leaks

Method What It Detects
Zone pressure test Static pressure drop confirms leak exists on specific zone; isolates affected zone from others
Head-by-head flow isolation Capping heads progressively isolates break location to a 5-10 ft pipe section
Visual surface inspection Wet surface, lawn discolouration, and ground depression narrow search area before digging
Listening device (acoustic) High-flow breaks detected by pipe resonance; used on deep breaks where surface indicators are absent
