How can an operator correct the problem of an airlocked pump housing?

An airlocked pump housing occurs when air becomes trapped in the pump, preventing it from functioning properly, as the presence of air disrupts the flow of water. To remedy this situation, one effective method is to leave the motor on while opening the spigot. This action allows water to flow through the system, creating a pressure differential that enables any trapped air to escape from the pump. As the pump operates, the continuous movement helps push the air out, thereby restoring the pump's functionality.

This method is advantageous because it allows the pump to maintain its operational state without needing to shut it off, which can be disruptive and time-consuming. It also takes advantage of the hydraulic principles at play, effectively clearing the air blockage without the need for additional modifications or relocation of the pump.

Other options, such as shutting off the motor and restarting it after several minutes, may not effectively resolve the airlock since it does not actively address the air trapped in the pump. Submerging the pump in water may not be a practical solution either, as it could be physically impossible depending on the pump's installation location. Changing the location of the pump isn't a feasible or efficient resolution to an airlock situation, as it doesn't directly address the air trapped inside the pump housing
