Irrigation systems should be winterized each year before the first freeze to avoid damage. Once winterized, the system will be turned off and restarted in the spring. If you are unsure of how to drain your irrigation system, contact a licensed plumber or building professional. See Yavapai County Contractors Association website.

Winterizing irrigation system basics:

  1. Turn off the water to the irrigation system at the main valve.
  2. Insulate and freeze proof the backflow prevention device and valves.
  3. Set the automatic irrigation controller to the “rain” setting.
  4. Turn on each valve to release pressure in pipes.
  5. Drain all water from irrigation components that might freeze.

And don’t forget to winterize your rain barrel (steps may vary based on system):

  1. Disconnect the rain barrel from the gutter downspout.
  2. Empty barrel of all water. Make sure to drain the water from attached hoses as well.
  3. Clean the inside of the barrel.
  4. Store your rain barrel in a dry place or upside-down.
  5. During the winter, you should reconnect the gutter downspout.
