What is the first step in the end-of-season shutdown process for irrigation systems?

• A. Clean filters
• B. Drain water from freezable parts
• C. Open valves
• D. Turn off the controller

Answer: (A)

The first step in the end-of-season shutdown process for irrigation systems is to drain water from freezable parts. This action is critical because leaving water in components such as pipes, valves, and sprinklers can lead to freezing and consequent damage during cold winter months.

By removing water from these areas, you protect the system from breakage and costly repairs. Additionally, draining helps to prepare the system for maintenance and any necessary repairs that can be conducted during the off-season.

While cleaning filters, opening valves, and turning off the controller are essential steps in the shutdown process, they are typically completed after ensuring that all water is removed from components at risk for freezing. Thus, draining water from freezable parts takes precedence as the vital first step in protecting the irrigation system for the winter.
