Sprinkler wiring problems usually come from a few common issues that interrupt the signal between the controller and the valves. Dallas Landscape & Irrigation often sees damage caused by age, moisture, rodent activity, or accidental cuts during landscaping work.
Common causes
- Broken or nicked wire from digging, edging, or trenching
- Corrosion in wire connections from water exposure
- Loose splices inside valve boxes or junction points
- Faulty controller terminals that no longer send power correctly
- Damaged insulation that leads to shorts or intermittent operation
- Rodent damage chewing through underground wiring
Warning signs include zones that will not turn on, multiple zones acting unpredictably, or a system that works only sometimes. In some cases, the issue may look like a valve problem when the real cause is wiring.
If you suspect an electrical issue, it is best to have a professional test the circuit before more damage occurs. Dallas Landscape & Irrigation can diagnose the fault, repair the wiring, and confirm each zone is receiving the proper signal. Request an estimate to get started.
