Daily verification of wash-water temperature and water filters should be performed by which method?

• A. Visual inspection of the built-in thermometer and flow meter
• B. Laboratory water testing
• C. External sensor readings only
• D. Visual inspection of external gauges only

Answer: (A)

Daily verification should be done by visually checking the built-in thermometer and flow meter on the wash system. These indicators are calibrated for the actual wash point, giving immediate, on-site confirmation that the wash-water temperature is within spec and that the water flow is adequate for proper cleaning and filter performance. It’s quick, practical for everyday QA, and doesn’t delay operations with lab analyses. Laboratory testing is not suitable for routine daily checks because it takes longer and uses more resources. Relying only on external sensors or gauges can miss how the system is actually performing at the wash point, since those readings may not reflect the true conditions experienced during operation. The built-in indicators provide the most direct, relevant verification for daily maintenance.
