How a Pedestal Sump Pump Works

If you’ve been reading up on basement waterproofing methods, you’re probably at least somewhat familiar with sump pumps. They’re responsible for moving water that builds up in the ground away from your home. What you may not know is that there are a couple different variations of sump pumps: submersible and pedestal. In this post, we’ll explain how a pedestal sump pump works and what makes it different from other pump types.

The Setup

The motor of a pedestal pump is set at the top of a pole, which is attached to a pedestal base. 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.


Pedestal pumps activate through a float that’s connected to an activation switch. Normally, the float is in a low-hanging position. When water comes into the pit through inlet pipes and reaches a certain threshold height, the float raises. As a result, the position of the activation switch changes, and the sump pump turns on.

The Difference

What distinguishes a pedestal pump from a submersible pump is that the motor has no contact with the water, so it doesn’t need a protective casing like a submersible pump does. Installation is therefore a simpler matter, and you don’t need to worry about leaks in the setup that could damage the motor. On the other hand, the sound of the motor working will be louder since it’s exposed in your basement rather than tucked away in the sump pit. It may also be a bit more prone to overheating since it doesn’t have water around it to naturally cool it as it works.

Ultimately, the type of sump pump you get is up to personal preference, though a waterproofing professional may advise one or the other, depending on each individual situation.
