If you live in an area of the country that’s prone to storms and heavy rains, you know of the potential negative effects of rising groundwater levels, especially in a basement. Improper water drainage can lead to serious flooding, expensive or irreparable water damage, and even mold. To help mitigate these risks, homeowners with basements can consider investing in a high-quality sump pump. This handy submersible device is designed to deal with water that collects where it shouldn’t, especially below-ground. When your sump basin fills up, your sump pump activates to move the water into a drain or the main plumbing system in your house to be disposed of with the rest of your wastewater. The best sump pumps are powerful but quiet, and will help keep your basement dry even after the most aggressive storms.
Our Top Picks
We considered factors such as horsepower, flow rate, material, form factor, and cost to determine the best sump pumps.
The Zoeller M53 Mighty-Mate Submersible Sump Pump is a 3/10-horsepower motor that can pump around 2,500 gallons per hour when the water must be lifted five feet, though this capacity may vary slightly if on ground level or at a greater depth. The switch case, motor, and pump housing are all made from cast iron, and though the base is plastic, it’s still a sturdy choice. The 9-foot power cord provides enough length to run to the nearest GFCI protected outlet. The float will shut the pump off automatically when the pit is nearly empty. This is a reliable choice for both residential sump pits and septic tanks.
The WAYNE WWB WaterBUG Submersible Pump can be used on flat roofs, standing water in your yard, or for any other similar outdoor application. However, it can also be used indoors as an alternative to a standard sump pump or to clear areas that are already flooded, in the basement, or otherwise. The WaterBUG removes water all the way down to 1/16 of an inch, which is far lower than the majority of sump pumps. It’s also much more compact than average sump pumps, so it can get rid of water in tight spaces. The maximum flow rate is 1,257 gallons per hour, or 900 gallons per hour at 10 feet of lift.
The 1/3-horsepower motor is still a solid choice if you need a submersible sump pump. It pumps up to 4,600 gallons per hour at a flat discharge height and 3,060 gallons per hour at 10 feet of discharge lift. The cast iron improves this pump’s durability and overall life span. The mechanical float switch provides reliable operation and allows for installation in sump basins 11 inches or larger. The top suction strainer filters out debris to protect the pump from clogging and improve its performance. The pump also comes with an 8-foot, water-resistant power cord. The WAYNE CDU790 is easy to install and is fully submersible in your basement’s sump basin.
