As the temperatures drop, it’s crucial to protect your irrigation system from winter damage.

At Rodriguez Irrigation & Backflow Services, we provide expert winterization sprinkler systems and winterization irrigation systems services in Issaquah, WA, to help keep your system in top shape for the next season.

  • Closing the main irrigation shut-off valve (curve stop valve) if applicable

  • Setting the irrigation controller to the “off” position
  • Providing a list of any repairs or problems that can be addressed during spring activation
