Abstract
Apparatus, including a pumping system, is provided featuring a pump and a control circuit. The pump has an impeller housing configured with a slit at the top for trapped air to leave the impeller housing once the pump has been submerged. The control circuit is configured to cycle the pump on and off for a predetermined number of cycles so that the trapped air will float to the top and be expelled out the slit when the pump is cycled off. The control circuit is configured to leave the pump on after the predetermined number of cycles.
