When selecting a sump pump for your home, it’s important to consider factors such as cost, power, noise level, and ease of maintenance. By understanding the pros and cons of pedestal and submersible sump pumps, you can make an informed decision to find the best fit for your needs.

Sump Pump Components

Float Switch

A vital component of your sump pump is the float switch. This device is responsible for detecting the water level within your sump pit. As the water rises, the float switch activates the pump to discharge excess water, preventing basement flooding. There are various types of float switches, including tethered, vertical, and electronic switches. It is essential to inspect and maintain your float switch regularly, ensuring it operates correctly when needed.

Check Valve

The check valve is another crucial part of your sump pump system. This valve ensures that the water being pumped out does not flow back into the sump pit once the pump shuts off. It maintains the water flow in one direction, preventing any backflow that could lead to basement flooding. It’s important to inspect your check valve for proper functioning and signs of wear or damage.


The impeller is the primary moving part within your sump pump. It’s responsible for creating the centrifugal force necessary to draw water into the pump and push it out through the discharge pipe. The impeller must be in good condition for your sump pump to operate efficiently. Keep an eye on the impeller for signs of wear, obstruction, or damage, which could negatively impact your pump’s performance.

Battery Backup

A battery backup sump pump system is an essential addition to your primary pump, offering a reliable source of power during power outages or pump failures. The battery backup ensures that your sump pump continues to function, removing water from your basement and reducing the risk of flooding. It’s crucial to maintain and periodically test your battery backup sump pump to ensure it’s ready for use during emergencies.
