What Toronto Homeowners Should Know About
Why Is My Sprinkler System Skipping a Zone?

Why is my sprinkler system skipping a zone?

A sprinkler system usually skips a zone because that zone has no run time, is not assigned to the active program, has a bad solenoid, has a cut wire, or is being interrupted by a controller setting. If the skipped zone works manually, the problem is likely programming. If it does not work manually, test the wire, solenoid, and valve.

Diagnosis Steps

How to Narrow Down
the Real Sprinkler Problem

sprinkler system skipping zone sprinkler repair diagnosis

Best first checks

  1. Run skipped zone manually
  2. Check run time is not zero
  3. Review all programs and start times
  4. Test voltage at zone terminal
  5. Inspect solenoid and field wiring if manual test fails
Detailed Explanation

Why This Happens in
Toronto Irrigation Systems

The fastest test is manual operation. If the zone runs manually from the controller, review program start times and run times. If it does not run manually, check electrical output and valve operation.

After controller replacement, spring startup, or service work, skipped zones are often caused by programming rather than broken parts.
