When a sprinkler emergency hits — a zone stuck on, a broken pipe gushing water — every Calgary homeowner needs to know exactly where their irrigation shut-off valve is. This guide covers the most common shut-off valve locations in Calgary homes and how to identify which valve turns off your irrigation system.
Where to Find Your Calgary Irrigation Shut-Off Valve
| Home Type | Typical Shut-Off Location |
|---|---|
| 1980s-1990s Calgary bungalow | Utility room (basement) — ball valve on ¾” copper pipe before it exits through the wall |
| 2000s-2010s two-storey | Mechanical room or utility closet — often labelled “Irrigation” or “Outdoor” |
| Newer homes (2015+) | Near the backflow preventer assembly in a valve box outside, at front of house |
| Backflow preventer location | Green valve box near front foundation or at the side of the house near water meter |
| If no separate valve found | Turn off main house water at water meter — stops all water including irrigation |
Valve Types and How to Turn Them Off
Ball valve (lever handle): turn the handle 90° perpendicular to the pipe = CLOSED. Gate valve (round wheel): turn clockwise until it stops = CLOSED. Backflow preventer handle (two small handles): both handles parallel to their respective pipes = OPEN; both handles perpendicular = CLOSED. If you're unsure which valve to close, call J.G. Irrigation at 587-433-4795 and describe what you see — we can walk you through it.
What if I can't find my Calgary sprinkler shut-off valve?
If you cannot locate your irrigation shut-off valve and have a running zone or emergency, turn off the main water supply to your home — the main shut-off is typically near the water meter in the utility room. This stops all water including irrigation. Then call J.G. Irrigation at 587-433-4795 for emergency service and we will locate and label your irrigation valve during the repair visit.
