All Stations Dead After Head Replacement: Check for Cut Wire

Replaced a sprinkler head, now no stations work. Most likely: shovel cut the common wire near the repair.

Checklist

1. Inspect dig area for cut wires (common is usually white).
2. Verify controller has power (display on).
3. Verify main irrigation water valve OPEN.

If Wires Intact

• Test controller output voltage (24VAC at station terminals).
• Check common wire at valve box.
• Could be coincident controller failure—but cut wire is #1 suspect after digging.

Mother's Day deadline: check the dig site first. A nicked common wire kills the whole system.
