What maintenance step is essential to prevent debris from affecting valve operation?

• A. Regular inspection of wiring
• B. Frequent system flushes
• C. Cleaning filter screens
• D. Checking the power source

Answer: (C)

Cleaning filter screens is essential for preventing debris from impacting valve operation. Over time, irrigation systems can accumulate dirt, leaves, and other particulate matter, which can clog the filter screens. When these screens become blocked, water flow to and from the valves may be restricted, leading to inefficient system performance or even valve failure. By regularly cleaning the filter screens, the system can maintain adequate water flow, ensuring that valves operate smoothly and effectively without obstruction.

In irrigation systems, each component's functionality relies on the unobstructed flow of water. Therefore, maintaining the cleanliness of filter screens directly contributes to the overall efficacy and longevity of the irrigation system, making this maintenance step crucial. Regular inspection of wiring, frequent system flushes, and checking the power source, while important for specific operational aspects, do not address the immediate issue of preventing debris-related problems with valve operations.
