A sump pump is a device that helps prevent flooding in basements and crawl spaces by removing excess water that accumulates in a sump pit. Sump pumps are commonly found in homes and buildings located in areas with high water tables or frequent rainfall.

If you’re a homeowner or building manager, learning about sump pumps can help you prevent water damage and costly repairs. Here are some things you should know about sump pumps:

Types of Sump Pumps

There are two main types of sump pumps: submersible and pedestal. Submersible pumps are installed inside the sump pit and are designed to be completely submerged in water. Pedestal pumps are installed above the sump pit and are designed to be partially or completely out of the water.

Submersible pumps are generally more expensive than pedestal pumps but are also more efficient and quieter. Pedestal pumps are often used in older homes or buildings where the sump pit is too narrow for a submersible pump.

How Sump Pumps Work

Sump pumps are designed to prevent water from flooding and damaging basements or crawl spaces. These pumps work by collecting water that has accumulated in a sump pit or basin, typically located in the lowest point of the basement or crawl space. When the water level in the sump pit reaches a predetermined level, the pump is activated and begins pumping the water out of the pit and away from the home’s foundation through a discharge pipe.

How Sump Pumps are Powered

Some sump pumps are powered by electricity, while others rely on a backup battery or water pressure to function. Sump pumps can help to prevent water damage, mold growth, and structural damage caused by flooding or excess moisture. It’s important to regularly maintain and test your sump pump to ensure that it is functioning properly and to prevent potential damage to your home.

Sump pumps work by automatically detecting when the water level in the sump pit rises above a certain level. Once the water level is detected, the pump is activated and begins to pump water out of the pit and away from the building. Most sump pumps are powered by electricity and have a backup battery in case of power outages.


Like any mechanical device, sump pumps require regular maintenance to ensure they function properly. It’s important to check your sump pump periodically to ensure it’s free of debris and to make sure the float switch is working correctly. You should also test the pump regularly to ensure it’s working properly.

If you notice any issues with your sump pump, such as strange noises or water not being pumped out of the pit, you should contact a professional to inspect and repair the pump.


Sump pumps are an essential tool in preventing water damage in homes and buildings. By understanding the different types of sump pumps, how they work, and how to maintain them, you can help ensure your property stays dry and safe. If you’re unsure about the condition of your sump pump, it’s always best to contact a professional to inspect and repair it.
