ESP shall be cleaned a minimum of how often?

• A. Daily
• B. Weekly
• C. Monthly
• D. Annually

Answer: (B)

Regular maintenance includes keeping the ESP clean to ensure it remains accessible and ready to operate. Cleaning at least once a week prevents grease, dust, and moisture from building up on the unit, which can obscure labels, contaminate seals, or obscure indicators and make quick inspections harder. A weekly cadence hits a practical balance: it’s frequent enough to catch and remove buildup early, while not being so demanding that daily cleaning becomes impractical. Cleaning more often than weekly is usually unnecessary for most environments, while waiting longer than a week increases the chance that issues or grime go unnoticed.
