Which should be done on all pumps and motors?

• A. Clean and rebuilt annually
• B. Inspect on regular basis and log observations
• C. Replace every 3 years
• D. Lubricate weekly to install maximum performance

Answer: (B)

Regular inspection of pumps and motors with a written log of what you observe is the baseline maintenance practice for wastewater equipment. This approach helps you catch early signs of trouble—such as unusual noises, abnormal vibration, overheating, leaks, loose electrical connections, misalignment, or changes in lubrication status—before a failure occurs. By recording observations over time, you can track trends and schedule maintenance proactively, reducing downtime and extending equipment life. Therefore, routine inspections with documentation are the best practice for all pumps and motors.

Cleaning and rebuilding annually isn’t universally required or practical for every unit, and replacement on a fixed schedule ignores actual condition. Lubricating weekly to maximize performance isn’t universally appropriate either, since lubrication intervals depend on bearing type, lubricant, and operating conditions.
