Home Sprinkler Controller Repair

Your sprinkler controller is the brain of your entire irrigation system. When it fails or is programmed incorrectly, no amount of valve or head repair will make the system work right. We diagnose, repair, and program all types of sprinkler controllers in San Marcos — from basic timers to smart Wi-Fi controllers.

Sprinkler Timer and Controller Problems

  • Controller not turning zones on at scheduled times
  • All zones running at once or in the wrong order
  • Display not working or showing error codes
  • Controller running zones that were turned off
  • Zones running too long or not long enough
  • Controller not responding to manual operation
  • Lost programming after a power outage
  • Smart controller not connecting to Wi-Fi or weather service

Controller Not Turning Zones On

When a controller appears to be running but zones don't activate, the problem could be in the controller's output terminals, the wiring between the controller and valve, or the valve itself. We test each component in sequence to isolate the fault without replacing parts blindly.

Incorrect Watering Schedule

An improperly programmed controller can waste significant water — running zones during peak heat, overwatering turf, or running on restricted days under San Marcos's watering rules. We reprogram your controller to a water-efficient schedule that complies with current city restrictions.

Smart Sprinkler Controller Upgrades

If your old dial-type timer is failing, this is an ideal time to upgrade to a smart controller. Smart controllers use weather data to skip watering when rain is expected, adjust runtimes based on temperature and season, and allow you to control your system from your phone. We install and program Rachio, Rain Bird WiFi, Hunter Hydrawise, and other popular smart controllers.

Programming for San Marcos Watering Rules

San Marcos has active water conservation stages — Stage 1, 2, and 3 — that restrict which days and times residential and commercial systems can run. We program your controller specifically for current restrictions and show you how to adjust it if restrictions change. Always verify current restrictions at the City of San Marcos website.
