A pedestal sump pump is a type of pump used to remove accumulated water from a sump basin, typically found in the basement of homes. It is designed to prevent flooding and manage water accumulation, especially in areas prone to high water tables or heavy rainfall.
The pedestal sump pump consists of two main parts: the motor and the pump itself. The motor is mounted on a long shaft above the sump basin, keeping it out of the water, while the pump is located at the base of the shaft, submerged in the water. This design allows the motor to stay dry, reducing the risk of damage and extending the pump's lifespan.
The pump operates using a float switch, which is a buoyant device that rises and falls with the water level in the sump basin. When the water level rises to a predetermined point, the float switch activates the motor. The motor then powers the impeller, a rotating component that creates a centrifugal force to push water through the pump and out through a discharge pipe. The water is then directed away from the home, typically to a storm drain or a dry well.
Once the water level in the sump basin drops to a certain level, the float switch deactivates the motor, stopping the pump. This automatic operation ensures that the pump only runs when necessary, conserving energy and reducing wear and tear.
Pedestal sump pumps are known for their durability and ease of maintenance, as the motor is accessible for repairs or replacement. They are ideal for situations where the sump basin is narrow or shallow, as the motor does not need to be submerged. However, they can be noisier than submersible pumps due to the motor's exposed position.
