Quick answer: Damaged sprinkler wiring can cause one or more valves to stop operating, work intermittently, or show controller fault messages. Electrical testing can distinguish a broken conductor or bad splice from a failed solenoid or controller problem.
Common signs of field-wire problems
- One zone suddenly stops working
- Several zones sharing a common wire fail together
- Controller reports a short or fault
- Zone operation changes after digging, landscaping or utility work
- Intermittent operation appears after wet weather or soil disturbance
Why visual inspection is not enough
Most irrigation control wire is buried, and failures frequently occur at underground splices or damaged sections that cannot be seen from the surface.
How professionals narrow it down
Voltage, resistance and continuity testing can identify whether the electrical path is intact. Wire-tracing equipment can then help follow buried control wire and locate valves without random excavation.
