What is an indicator of poor pump performance?

• A. High water flow
• B. Stable vacuum reading
• C. Excessive noise from the pump
• D. Increased resistance in hoses

Answer: (C)

An indicator of poor pump performance is excessive noise from the pump. When a pump operates efficiently, it usually runs smoothly and quietly. However, excessive noise can signal underlying issues such as cavitation, where vapor bubbles form in the pump due to low pressure and subsequently collapse, causing vibrations and noise. This could indicate that the pump is struggling to draw in water or is not performing optimally. Additionally, noise can be a sign of mechanical wear or damage within the pump components. In contrast, high water flow typically suggests that the pump is functioning well, and stable vacuum readings are indicative of a healthy pump system. Increased resistance in hoses can affect pump performance, but it is not a direct measure of the pump itself, as it could be influenced by other external factors in the system configuration. Thus, recognizing excessive noise is crucial for diagnosing and addressing potential pump performance issues effectively.
