What should be checked regularly to ensure optimal performance of a lift pump?

To ensure optimal performance of a lift pump, monitoring the water level in the sump is critical. The water level directly affects the pump's operation; if the water level is too low, the pump may operate dry, leading to overheating and potential damage. Conversely, if the water level is too high, it can cause the pump to work harder than necessary, which can lead to wear and tear or inefficiencies.

Maintaining an appropriate water level ensures that the lift pump operates within its designed parameters, allows for proper suction, and minimizes the risk of failure. Therefore, regular checks of the water level in the sump are essential for ensuring the reliable and efficient operation of a lift pump.
