How long can the pump run before running dry when using the 1 ¾" Pre-Connect?

When using the 1 ¾" Pre-Connect, the pump can run for up to 4 minutes without taking on additional water, otherwise known as running dry. This duration is critical as running the pump dry can lead to severe damage, including overheating and potential failure of the pump. The 4-minute limit is established to allow firefighters sufficient time to establish a water supply while minimizing the risk of damaging the pump.

Understanding the importance of this time frame ensures that operators are aware of the consequences of pump operation without water and encourages prompt actions to secure a reliable water source when utilizing this type of line. This knowledge can significantly impact operational efficiency and the longevity of the equipment when responding to emergencies.
