Which action at a lift station should be performed monthly?

• A. Check electrical connections
• B. Inspect pumps
• C. Test backup generator
• D. Repaint enclosure

Answer: (A)

Regular maintenance at a lift station centers on keeping the electrical system reliable, because power to the pumps and controls is critical for continuous operation and safety. Performing a monthly check of electrical connections helps catch loose terminals, corrosion, or damaged insulation before they cause a failure or fire. Connections can loosen from vibration, moisture, or temperature changes, and a quick monthly inspection is an effective way to prevent outages and keep the system safe. While inspecting pumps, testing the backup generator, or repainting the enclosure are important tasks, they follow different maintenance schedules—pump checks are part of planned pump maintenance, generator tests are done on a dedicated routine to ensure readiness, and repainting is cosmetic and not a monthly requirement.
