Underground Sprinklers Winterization Procedure:
Winterizing your underground sprinkler system is a must to ensure that it doesn’t freeze and damage pipes, valves, and sprinkler heads. The first stage of the process is the shutdown of the water supply to the whole system. Then the system is drained using one of the following three methods: manual, automatic, or blowout. The most common is the blowout method, which entails using compressed air to force All water is removed from the pipes. The result of draining can be seen as when it is accomplished it leads to produced a situation when water doesn’t exist and there is no risk of pipes getting frozen and bursting during the winter. After blowing out the water, it’s important to open any manual valves to release pressure and check the backflow preventer to ensure it’s properly drained. Besides, covering exposed parts like sprinkler heads can shield them from snow and ice. By following these steps the sprinkler system is going to be away from the actions of the winter which usually means costly repairs and it is going to be almost new for the spring.
Underground 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
