A submersible sump pump sits completely inside the pit, underwater, while a pedestal sump pump has its motor mounted on a column above the pit with only the intake at the bottom. Both remove water from the basement, but they differ in noise, power, lifespan, and how they fit your pit.
Submersible Pumps
The motor is sealed inside a waterproof housing and sits under the water. Because the water and the pit cover muffle the sound, submersible pumps are usually quieter. They often move more water, which makes them a common choice for basements that get a lot of water. They also fit under a sealed lid, which keeps out debris and helps with odors.
Because the motor sits in water, it may wear out sooner and can be harder to reach for service.
Pedestal Pumps
The motor sits above the pit on a tall stand. Since it stays dry, it can last longer and is easier to reach for repairs. Pedestal pumps can work well in small or narrow pits where a submersible would not fit. They are usually louder, take up more space above the floor, and may move less water.
How to Choose
- How much water your pit collects during heavy rain
- The size and depth of your pit
- Whether noise matters, such as in a finished basement
- How easy it is to reach the pump for service
- Whether you plan to add a battery backup
Other Factors
Pump power, the height the water must be lifted, and the length of the discharge line all affect which model works best. Choosing a pump based on price alone can lead to a pump that runs too often or cannot keep up.
If your current pump is failing, repairing or swapping the pump before the next storm protects your basement. If you are still deciding, you can weigh the two pump types with a plumber by calling (833) 603-1840.
