Critical pump equipment that is operated continuously may require ______ inspections; less critical pump equipment may be inspected ______.

• A. weekly, monthly
• B. monthly, annually
• C. annually, monthly
• D. daily, quarterly

Answer: (B)

Regular preventive maintenance scales with how important the pump is to service and how it operates. If a pump runs continuously, a small fault can quickly lead to a shutdown or burst of unscheduled downtime, so inspections must be more frequent to catch problems early. Monthly checks give time to review lubrication, seals, bearings, alignment, vibrations, and electrical connections, allowing proactive repairs before a failure disrupts water distribution.

Less critical pumps still require oversight, but the risk of immediate service impact from a fault is lower, so inspections can be done on a longer cycle. Annual inspections strike a balance, providing enough opportunity to assess general condition, corrosion, wear, and motor health without overburdening maintenance resources. Weekly, daily, or quarterly schedules would not align with the risk and workload balance for these categories.
