If you have a basement, you've probably heard of a sump pump.
Many homeowners don't think much about it until they find water on the basement floor after a heavy rain.

Do you really need one?
How long does it last?
And what happens if the power goes out during a storm?
In this guide, we'll answer the most common questions homeowners have about sump pumps in simple, easy-to-understand language. You'll learn how sump pumps work, how to maintain them, when they need to be replaced, and how to choose the right system for your home.
What Is a Sump Pump?
A sump pump is a machine that removes water from a pit, called a sump pit, located in the lowest part of your basement. When water collects in the pit, the pump automatically turns on and pumps the water outside, away from your home's foundation. Without a sump pump, water can build up and increase the risk of a wet basement or flooding. Read more: What Is a Sump Pump?How Does a Sump Pump Work?
Most sump pumps work automatically. As water fills the sump pit, a float rises. When the water reaches a certain level, the float tells the pump to turn on. The pump pushes the water through a discharge pipe and safely away from your home. When the water level drops, the pump shuts off until it's needed again.
