Rain & Freeze Sensor Installation in San Antonio

Sensors that stop the system when the weather already did the job.

Texas law requires a rain or moisture sensor on new irrigation systems, and a freeze sensor protects your pipes and sidewalks during South Texas cold snaps. We install wired and wireless sensors and verify the interrupt works at the controller.

Signs you need this service

  • System runs in the middle of a thunderstorm
  • Ice sheets forming on the driveway in winter
  • Existing sensor is cracked, faded, or bypassed
  • You are bringing an older system up to code

How we handle it

  1. 1 Select a mounting point with clear sky exposure
  2. 2 Wire the sensor into the controller interrupt circuit
  3. 3 Test the shutdown and restart behavior
  4. 4 Set the sensitivity for local rainfall patterns
