As September rolls in, it’s time to think about winterizing your irrigation system. In Iowa, freezing weather comes fast, and if water is left in your sprinkler lines, it can expand and cause cracked pipes, broken fittings, and damaged sprinkler heads. The best way to protect your system is by using a towable Sullivan-Palatek air compressor.

Why Use an Air Compressor for Irrigation Blowouts?

When winter temperatures drop, even a small amount of water in your irrigation lines can cause major damage. Blowing out your system with compressed air ensures water is fully cleared, helping you avoid expensive spring repairs.

With Sullivan-Palatek, you get the power and consistency needed to handle residential or commercial irrigation systems.

Steps for Blowing Out Irrigation Lines

Residential & Small Commercial Systems:

  • Shut off the water supply.
  • Connect the air compressor to the system’s blowout port.
  • Set PSI between 50–80 to protect sprinkler heads.
  • Run each zone until only air comes out.
  • Repeat for all zones to ensure lines are completely dry.

Larger Systems (Golf Courses, Athletic Fields, Parks):

  • Larger irrigation systems may require higher-capacity compressors for long pipe runs.
  • Connect the compressor at multiple access points across the property.
  • Cycle each zone longer or multiple times to fully clear water, especially in low spots.
  • Maintain the same PSI range (50–80 PSI) to protect sprinkler heads and fittings.
  • Professional oversight is recommended due to system complexity.
