Controls and zone operation
Sprinkler Valve, Controller, and Wiring Repair
When a zone will not turn on, will not turn off, or ignores its schedule, the issue can be in the valve, solenoid, controller, wiring, or programming. Greater Aiken Irrigation tests the control path so the repair is based on the part that is actually causing the problem.
Common signs
- A zone does not start from the controller.
- A zone keeps running after the controller is off.
- The controller display is on but a scheduled cycle does not happen.
- A valve box floods or makes a persistent sound.
What can cause it
- A worn valve or solenoid.
- Damaged or disconnected zone wiring.
- Controller programming, power, or terminal issues.
- Water entering a valve box or affecting a connection.
What Travis checks
- Review the controller program and manual zone operation.
- Inspect the affected valve and solenoid where accessible.
- Trace visible wiring and connections.
- Test the system after the source of the fault is addressed.

Questions homeowners ask
Why will one sprinkler zone not shut off?
A valve or solenoid may not be closing correctly, though control wiring and programming should also be checked before assuming the cause.
Can an older irrigation controller be repaired?
The first step is checking its power, programming, terminals, and the zone response. That shows whether a repair or a replacement discussion is appropriate.
