Signs You Have an Underground Irrigation Pipe Leak in Calgary

• Soft wet patches in lawn — stays wet days after watering; most reliable indicator of mainline or lateral leak.
• Water pressure drop in zones — zone runs but heads under-rotate or miss coverage at far end.
• Unexplained water bill increase — a mainline break can flow 4-8 GPM continuously, adding 5,000-15,000L/week.
• Zone won’t build pressure — pressure escaping through broken lateral before reaching heads.
• Water bubbling at head base — cracked body or fitting below surface.

Common Causes of Underground Pipe Breaks in Calgary

• Freeze damage from incomplete blowout — leading cause. Under-spec compressor (below 185 CFM) leaves water in laterals; it freezes and splits fittings. Shows up at spring startup.
• Physical damage from landscaping — fence posts, tree planting, rotary tilling, or spade edging hits laterals at 14-18 inch depth.
• Tree root intrusion / age degradation — 1990s/2000s poly pipe past 20-25 year service life becomes brittle in Calgary NW/SW communities with mature trees.
