How Do Pedestal Sump Pumps Work

This motor sticks out of the sump pump, while the pedestal sits at the bottom. Inside the pedestal is an impeller, which is a rotor-shaped piece that spins to suck in water that collects in the pit. As the water is pulled into the pedestal, it’s redirected out of the pit through a pipe attached the pedestal.
