Screens on suction intakes must be inspected periodically for what reason?

• A. To prevent corrosion
• B. To assess water quality
• C. To check for noise
• D. Accumulated debris

Answer: (D)

Screens on suction intakes act as filters to keep debris out of the system. They must be inspected periodically because debris tends to accumulate on the screen over time. When the screen gets clogged, water flow is restricted, which lowers suction performance, reduces pressure at sprinklers, and can make the pump work harder or even overheat. This buildup can also allow larger particles to bypass or cause downstream blockages. Regular inspection and cleaning keep the intake free of debris, maintaining proper flow and protecting the pump and irrigation network. During inspection, look for visible buildup, rinse or brush the screen to remove it, and check that the mesh isn’t damaged so it can continue to filter effectively.
