How do I winterize my sprinkler system? PDF Print E-mail

We do not recommend winterizing your own sprinkler system unless you are completely familiar with all shut-off valves, backflow device, blow-out ports, extra lines or faucets, or any other unique features that were installed onto your system.

  • You must have an adequate sized compressor - minimum 2hp or 12 cfm @40ps. is recommended. If your system was properly installed, the design should be straightforward and easy to winterize.
  • Please refer to the diagram, "Backflow Device ."
  • Turn off the main sprinkler shut-off valve in basement.
  • Connect an air compressor (minimum 2 hp compressor or 12 cfm @ 40ps. recommended) to the sprinkler blowout port, which is usually just before the backflow device outside.
  • At the sprinkler timer, turn on one zone at a time until only "fog" comes out of each sprinkler head.
  • When finished with all zones, open the bleed ports on the backflow device momentarily to empty all the water from it.
  • Go through the entire system a second time. Turn off and disconnect the compressor.
  • Close the blow-out port.
  • Turn off the timer, but do not unplug it.
  • KEEP IN MIND - older systems or those that were not installed according to proper design standards may have more than one shut off and/or blow-out port. If you have any doubts about your system, contact Horizon or your local licensed irrigation professional to avoid costly freeze damage.
