What is the primary concern when there are air leaks during pump operations?

When there are air leaks during pump operations, the primary concern is reduced pressure in the system. Air leaks can introduce non-liquid air into the pump and the connected system, which disrupts the continuous flow of water. This can lead to cavitation, where air pockets form and cause fluctuating pressures. As a result, the efficiency of the pump is compromised, leading to an inability to maintain consistent pressure. This pressure loss can severely affect the overall firefighting operation, as inadequate pressure may hinder the fire suppression efforts. Ensuring a tight seal and addressing any air leaks is critical to maintaining effective and reliable pump performance.
