Winterizing your system ensures that your investment will operate properly for years to come, and will be ready for a smooth start-up come Spring time. Any water left in your underground lines will freeze and risks rupturing your irrigation conduit and damaging your heads. Kiwi’s professional team books winterization services from the last week of September to the first week of November to ensure that every system is completed before freeze-up.


Winterization is a simple but necessary process to ensure a long lasting system, and an easy start-up next Spring:

  • Turn Off Irrigation Valve – Inside your house in the basement.
  • Attach Compressor – To main line. 185 CFM Residential, 400 CFM Commercial.
  • Blow out all zones – Removing water from all lines and heads.
  • Turn off Timer – Turn off timer in preparation for Spring.
