Winterizing your irrigation system is crucial to prepare it for the winter season here in North Carolina. Fortunately, professionals have a tried-and-true process for winterizing irrigation systems. First, they'll shut off the water supply and turn off the timers and controllers. Then, they'll remove any remaining water in the pipes to ensure it doesn't freeze and cause damage. After that, they'll disconnect and drain the pump before removing, storing, and insulating the above-ground components, such as the backflow preventer. By following these steps, pros will ensure your irrigation system is ready to withstand the cold temperatures and be in good shape for the next growing season.


Professional Irrigation Winterization Involves Turning off Your System's Water Supply, Timers & Controllers

The first step professionals will take when winterizing your irrigation system is to shut off the main water supply. This step is crucial because it prevents any more water from entering the pipes, which can freeze and expand, causing them to crack or burst. After shutting off the water supply, they'll turn off the timers and controllers. This step ensures that your irrigation system doesn't try to run while winterized, which can lead to unnecessary wear and tear on the components.

This step is crucial because any remaining water in the pipes can freeze and expand, causing them to crack or burst. To do this, they'll drain and flush out the water, ensuring that anything leftover is removed from each zone before moving on to the next one. This step requires precision and expertise to ensure that all the water is removed without damaging the pipes or other components of your irrigation system.
