A Complete Guide to Sump Pumps

What Is a Sump Pump? 

A sump pump is a small device installed in the lowest point of your basement or crawlspace. Its primary function is to keep the space under your home dry and free of flooding. While any basement can benefit from a sump pump, it is especially pertinent for homes in flat or low-lying areas, regions with soil that readily traps water, and areas of high precipitation. But thanks to the U.S. Federal Clean Water Act of 1987, sump pumps are now a requirement in all new construction homes.  

What Makes Up a Sump Pump?

The sump pit is a 2-feet deep, 18-inch wide hole with a gravel or concrete base. It is dug into the lowest part of your basement or crawlspace. The sump pump rests inside this pit or on top of it, depending on which model you have. The discharge pipe protrudes out of the pit and extends upward, leading either to your yard or the main sewer line. Inside the hole, there is also a float, which is essential to the device operating correctly.

How Does It Work? 

Once activated, the device removes the water from your basement in one of two ways, depending on the type you have. The most common is a submersible pump. With this model, the tiny, spinning blades inside the pump’s impeller drive water toward the sides of the discharge pipe, creating an area of low pressure. Any remaining water rushes into this area and is pushed up and out of your house through centrifugal forces.

The second type is a pedestal pump. With this model, the pump rests on top of the pit, rather than inside it. This device removes flood water by drawing it out through an inlet pipe positioned at the bottom of the hole. It is louder than submersible models, but it is also cheaper to install.
