Automatic Sprinklers Winterization Procedure:
Ensuring the proper winterization of an automatic sprinkler system will be very useful for keeping you safe from freezing temperatures and saving the pipes, valves, and sprinkler heads from being damaged. The first step is turning off the water supply to the system. Then, the automatic controller should be turned off or put in “rain mode” to avoid the risk of any events during the winter season. The system must be drained subsequently. In cases of automatic systems, this may be done through the drain valves the system has or the popularly recommended blowout method. A powerful stream of compressed air is utilized to get rid of any water that may be left in the pipes and to ensure no water remains to freeze and expand. Once the system is off, it is absolute to open all the manual valves leaving the system and ensure that the backflow preventer is drained. It is also suggested to protect open sprinkler heads and other units from ice build-up. By doing the right winterization, the system will remain intact and will be ready for use in spring time!
Automatic Sprinklers Winterization Checklist:
- Turn Off Water Supply: Closing the main water supply line to let no water enter the system is the easiest way to avoid water entering the system.
- Shut Off Controller: Make sure the irrigation controller is in either “off” mode or “rain mode.” Setting the controller in this way ensures that no water will be used during the specified rain mist time.
- Drain the System: Drain the pipes manually or by using automatic drain valves, or, alternatively, blow them out with an air compressor.
- Check Sprinkler Heads: Investigate exposed to weather sprinkler heads and remove particles.
- Insulate Backflow Preventer: Make use of insulation materials or covers for protection
