Which of the following is NOT one of the steps in a pre-season check-up for irrigation systems?

• A. Flush irrigation system
• B. Turn off controller
• C. Clean filter screens
• D. Check irrigation controller date and time

Answer: (B)

Turning off the controller is not a step in a pre-season check-up for irrigation systems. Instead, the focus during this check-up is on ensuring that the irrigation system is operational and ready for use. To prepare for the upcoming season, it is essential to flush the irrigation system, clean filter screens, and check the controller's date and time to confirm it is set appropriately for the watering schedule. These actions help to prevent clogs, ensure efficient water delivery, and ensure that the irrigation system operates at optimal performance throughout the season. Conversely, turning off the controller would not assist in activating the system for watering, which is the intended purpose of the pre-season check-up.
