Simply put, a sump pump’s job is to keep water out of your basement. Installed in a small pit (called a sump basin) beneath the lowest part of your basement or crawlspace, a sump pump collects and expels groundwater before it can rise to the surface and flood your basement.

Here’s a closer look at how sump pumps work:

Water collects in the sump pit because of heavy rain, poor drainage, or natural groundwater.
A float switch activates the pump once the water reaches a certain level.
The pump pushes water away from your home’s foundation through a discharge line.
Once water is removed, the pump shuts off until it’s needed again.

Most modern sump pumps are electric. Many homeowners install battery backup systems in case of power outages (when flood risk is the highest).

Does a Sump Pump Waterproof My Basement?

A sump pump plays a major role in flood prevention, but it doesn’t “waterproof” your entire basement on its own. That a sump pump “waterproofs” your basement is a common misconception. Sump pumps work best when paired with other drainage and moisture-control systems, like:

Interior or exterior drain tile
Vapor barriers
Foundation crack repair
Functional gutters and downspouts

Think of a sump pump as your emergency eject button. It doesn’t stop water from coming near your foundation, but it prevents it from collecting where it can cause damage.

Do All Homes Need Sump Pumps?

Not every home needs a sump pump. However, many do. Here are some signs you should install and maintain a sump pump:

You live in a low-elevation or flat area where water easily collects.
Your basement has flooded in the past.
You have a finished basement with flooring, drywall, or valuables.
You notice musty odors or dampness after storms.
Your gutters or landscaping aren’t enough to direct water away from your foundation.
You’re in a region with heavy seasonal rainfall or snowmelt

Even if your home hasn’t flooded yet, a sump pump can give you peace of mind and prevent you from scheduling costly future repairs.
