If you have a basement or crawlspace, a sump pump might be one of your best lines of defense. It’s designed to keep water out and prevent flooding when heavy rains or groundwater buildup threaten your space. Whether you’re new to sump pumps or need a refresher, here’s a breakdown of how they work and why they matter.
What Is a Sump Pump?
A sump pump is a device that helps move water away from your foundation. It’s usually installed in a sump basin pit at the lowest point of your basement or crawl space.
The pump activates when water enters this pit, either from rainfall, melted snow, or rising groundwater. It moves the water through a discharge pipe and out to a safe location away from your structure. That water can quickly lead to flooding and costly damage without a sump pump.
The system includes three key parts:
- Sump pit: Collects water entering from perimeter drains or natural seepage.
- Pump: Detects rising water and powers it on to remove it.
- Discharge line: Carries the water away to a proper drainage area.
How Does a Sump Pump Operate?
Sump pumps work automatically, thanks to a float switch. As water fills the pit, the float rises. Once it reaches a certain level, the switch activates the motor.
The motor spins an impeller, which creates suction and pushes water through the discharge line. Most systems also include a check valve that stops water from flowing back into the pit.
When water levels drop, the float lowers, and the pump shuts off. This cycle repeats anytime water collects in the pit.
Types of Sump Pumps
Not all sump pumps are the same. Choosing the right one depends on your setup, moisture levels, and how often your pump runs.
Submersible Sump Pumps
These are installed directly in the sump pit and are fully sealed to operate underwater. They’re quieter and can handle higher volumes of water. Submersible pumps are ideal for finished basements or areas with frequent flooding.
Pedestal Sump Pumps
Pedestal pumps sit above the sump pit with the motor exposed. Only the base of the pump is in contact with water. They’re easier to maintain and generally last longer but can be louder. They’re a solid choice for smaller spaces or homes that don’t experience heavy water intrusion.
Backup Systems
Battery backup pumps kick in when the primary system fails or the power goes out. Water-powered backups use your home’s water pressure to remove water. Both options provide peace of mind during storms or outages.
Choosing the Right Sump Pump for Your Home
Your sump pump should match the size of your basement and the amount of water you typically get. You’ll likely need a more powerful system if your home is in a low-lying area or near a high water table.

Sump Pump Maintenance Tips
Routine maintenance keeps your sump pump working when you need it most. A few quick checks each season can prevent more significant issues later.
Here’s what we recommend:
- Make sure the pump is standing upright in the pit.
- Check the power source and test the float switch.
- Clear debris from the sump pit and discharge line.
- Listen for unusual noises or cycling issues.
- Schedule a professional inspection once a year.
