What occurs if a pump is not properly vented during operation?

When a pump is not properly vented during operation, trapped air can cause significant issues within the system. Specifically, this trapped air can lead to cavitation, a condition where vapor bubbles form in the liquid being pumped due to a drop in pressure. These vapor bubbles can collapse violently, creating shock waves that may damage the pump's internal components, such as the impeller or the casing.

Inadequate venting can also result in the pump running dry, which can lead to overheating and additional mechanical failure. This potential for physical damage underscores the importance of ensuring that the pump is properly vented to maintain safe operation and longevity of the equipment. Such vigilance is vital for effective water supply, as it helps prevent costly repairs and ensures the pump operates smoothly.
