Winterizing an automatic sprinkler system involves several key steps to prevent freezing and damage. Firstly, turn off the water supply and drain all the water from the pipes, valves, and sprinkler heads. Use an air compressor to blow out any remaining water in the system, being careful not to exceed the recommended air pressure. Finally, insulate any above-ground components such as backflow preventers and valves. This process protects your system, ensuring it remains functional for the next watering season.
