Your irrigation controller shows the schedule is programmed, but nothing turns on. This guide covers every reason a Calgary irrigation system might refuse to start — from controller faults to valve wiring to seasonal shutdown left on — and what each fix involves.
Sprinkler System Not Starting Calgary — Checklist
| # | Check This First | Resolution |
|---|---|---|
| 1 | Is the backflow preventer's shutoff valve open? | Turn ball valve parallel to pipe — fully open |
| 2 | Is the controller's seasonal adjustment at 0%? | Set seasonal adjustment to 100% — 0% = all zones off |
| 3 | Is the rain sensor showing “bypassed” or “active skip”? | Check rain sensor — if tripped after recent rain, wait or manually bypass |
| 4 | Controller shows “ERR” or error code | Short circuit in a zone wire — must trace and repair |
| 5 | Controller is blank / no display | Power issue — check outlet, transformer, circuit breaker |
| 6 | Manual “test all zones” also fails | Master valve fault or main supply issue — call J.G. Irrigation |
Items 1-3 on the checklist above account for approximately 60% of “system won't start” calls J.G. Irrigation receives in Calgary — they are simple settings checks that take 2 minutes. Items 4-6 require a professional technician. If you've checked 1-3 and the system still does not run, call 587-433-4795 for a same-day service visit — typically $90-$150 including diagnosis.
