Tilling Damaged Wires: Two Zones Run Simultaneously

Yard Tilling Caused Crossed/Nicked Wires: Two Zones On at Once

After tilling for fungus, system runs two zones simultaneously even if one has zero run time. Pressure already low. Need to know what tiller hit and how to fix.

Cause: Wire Damage During Tilling

The tiller likely nicked, cut, or cross-connected the valve wires. Maybe the operator tried a bad repair.

Fix Steps

1. Inspect valve boxes: each valve should have two wires. Check for wrong connections.
2. If wiring looks wrong, correct it.
3. If unsure, run new wires from controller to valves—cleanest fix.

If not comfortable, hire a landscaper/irrigation tech. Don't guess—wire faults are invisible but destructive.
