Irrigation Controller Installation & Repair In St. George, Utah
Utah Desert Landscape installs, replaces and programs irrigation controllers for St. George and Washington County properties — from upgrading an aging timer to diagnosing a controller that no longer runs its zones. Request a free estimate to discuss your system.
Irrigation Controllers
The Timer Decides When Every Zone Runs
The controller is the system's brain: it stores the schedule, signals the valves and determines when every zone waters. When it fails — or when its settings no longer match the season — the whole system suffers, no matter how sound the pipes and heads are.
Our Ivins-based team replaces aging and failed controllers, programs schedules that match Southern Utah seasons, and diagnoses situations where the controller, rather than the valve or wiring, is why a zone will not run. We also connect rain and weather sensors where the system supports them.
What’s Included
The Main Parts Of Your Project
Controller Replacement
Replace failed or outdated controllers with a unit suited to the system's zone count. We discuss the options available for your setup rather than pushing a particular model.
Programming & Scheduling
Set watering days, run times and seasonal adjustments. A schedule should reflect the landscape, the season and any current watering guidance — not a default program.
Wiring & Sensor Connections
Connect zone wiring correctly and add rain or weather sensors where supported. A sensor that actually interrupts watering during rain is a simple, worthwhile addition.
Troubleshooting
Diagnose controllers that will not power on, will not run zones or behave erratically. Sometimes the fix is settings or wiring rather than replacement.
The Process
From First Conversation To Installation
- 01
Describe The Behavior
Tell us what the controller does — blank display, zones that skip, schedules that will not save — or whether you simply want an upgrade.
- 02
Test Before Replacing
Confirm the controller is actually the problem. Power supply, wiring and settings are checked before recommending a new unit.
- 03
Install & Connect
Mount and wire the replacement or new controller, confirming each zone responds correctly.
- 04
Program & Explain
Set the schedule for the current season and walk you through the controls so future adjustments are easy.

Project Considerations
A New Controller Is Only As Good As Its Schedule
Replacing the unit without setting it properly changes nothing. St. George landscapes need schedules that shift with the season — more frequent in summer heat, scaled back in spring and fall, off during rain.
If zones are not running and you are not sure whether the controller or a valve is at fault, describe the symptom when you call. Our sprinkler valve page covers the valve side; the diagnostic visit settles which one needs attention.

Local Considerations
Controllers Working Through Southern Utah Seasons
Seasonal Schedule Shifts
Washington County watering needs swing widely between July and November. A controller review twice a year keeps the schedule honest.
Power & Heat
Garage-mounted controllers live through real heat, and outdoor units take direct sun. Placement and condition affect lifespan, which we consider when installing.
Watering Guidance
Local providers publish seasonal watering guidance. We can align your controller settings with current guidance for your property during programming.
