Sprinkler System Winterizing Tips
The weather conditions each year will determine the best time to winterize your sprinkler system. Although most of the system is underground and protected until the ground freezes, external parts like the back flow preventer and blow-out port can freeze from cold overnight temperatures. You will want to keep your system running as long as possible if you have new trees or have done a fall seeding.You should winterize as soon as you are sure you no longer need continual watering.

  • Complete aeration and seeding by Oct 15, and before winterizing your sprinkler system
  • Check your system to make sure all zones function before winterizing
  • Be sure all sprinkler heads appear to have full and even pressure indicating no heads are broken off and no pipe breaks exist.
