Tips on how to winterize your lawn sprinkler system

  1. 1. Benefits of using Lawn Sprinkler Systems Tips on how to winterize your lawn sprinkler system
  2. 2. Benefits of using Lawn Sprinkler Systems Each winter your irrigation system will need to be “winterized” to prevent the water lines from freezing and cracking. This involves blowing out the system with compressed air and turning the main valve off to prevent water from flowing back into the system and freezing.
  3. 3. Benefits of using Lawn Sprinkler Systems Winterizing your lawn sprinkler system is very simple but has to be done in proper way. Turn Sprinkler system off Turn off the water to the irrigation system at main valve. Deactivate electronic controller(s) and all valves in the system Drain all of the water out of the sprinkler system by air compressor
  4. 4. Benefits of using Lawn Sprinkler Systems For the simple reason that even after you have drained water out of the system, it is best to call a professional contractor for winterization due to, there could be some water remains in the pipe that can freeze, expand and crack the PVC piping. Polyethylene pipes are more flexible and can expand under pressure but, water left inside could freeze and burst the pipe walls. Freezing water in the backflow preventer will damage the internal mechanism.
  5. 5. Benefits of using Lawn Sprinkler Systems Blow-out Method It is recommended that a qualified licensed contractor performs a blow-out method to winterize your lawn sprinkler system. Serious personal injury may result if you do not proceed with care. One small mistake and you will no longer own a lawn sprinkler system. To winterize your lawn sprinkler system, you will need a commercial size air compressor. You need to carefully attach the compressor to the mainline through a quick coupler, hose bib or other type connection, which is located after the backflow device. Shut off the irrigation water supply, close the compressor valve then attach the air compressor hose to the fitting. Then slowly open the valve on the compressor. The blow out pressure should NOT exceed 80 PSI.
  6. 6. Benefits of using Lawn Sprinkler Systems You can start activating each zone from the furthest zone from the compressor slowly working your way to the closest zone to the compressor. Keep each zone activated until no water remains in the heads. Once the zone is dry, do not continue to blow air through the pipe. Continuing to blow air through dry pipe can damage. Turn off the controller after you are done blowing out the system. You can install the threaded caps over the open ends of the backflow preventer risers and any blow out fittings to keep garbage out until spring. Store the backflow preventer inside for the winter.
