6 Best Sump Pumps to Flood-Proof Your Basement
Updated on Nov. 21, 2024
Considering the time and financial cost of dealing with a flooded basement, a reliable sump pump is one of the most important purchases a homeowner can make. Placed inside the sump basin—the lowest point in your basement—the best sump pump automatically powers on when it detects rising water levels and efficiently expels it outside through a discharge pipe, preventing water from even reaching the basement floor.
This automatic operation means that even if you’re not home, you’re asleep, or you just don’t notice incoming water, the sump pump gets to work immediately—unlike a shop vac or utility pump that needs to be operated manually.
To note: Even the best sump pump requires regular maintenance to ensure it’s working properly. While annual testing is recommended for all models, busy sump pumps may need to be checked monthly.

Best Overall Sump Pump
Zoeller M53 Mighty-Mate
Zoeller has made high-quality, reliable products for over 70 years, and this highly regarded submersible model was an easy choice for our best sump pump. The cast-iron body and corrosion-resistant coating provide durability to last a long time, and the 1/3 horsepower (HP) motor pumps out up to 2,580 gallons of water per hour (GPH). A non-clogging impeller allows debris particles up to 1/2-inch in diameter to pass through, so even during severe storms or flooding, it will continue running smoothly and efficiently.
“I bought and returned several pumps from the box stores before I found this,” writes Andrew Griggs in his 5-star review. “It’s the exact pump I’m replacing that is over 20 years old. The setup was really easy and it’s working great. Sleeping easy tonight.”

- Built to last, professional grade
- 1/3 horsepower (HP) motor
- Flow rate of 43 gallons per minute (GPM) and 2,580 gallons per hour

Best Dual-Float Sump Pump
The Basement Watchdog SIT-50D
Be confident that your sump pump will activate every time, without fail, with this cast-iron Basement Watchdog pump and its ring-shaped, dual-float switches. The caged design prevent wires or debris from impeding the floats, but if for any reason the lower floating ring fails to initiate the pump and the water rises, it will activate the second. This 1/2 HP submersible model also boasts an impressive 4,400-GPH flow rate, while still having a small enough footprint to fit into narrow sump pits.
“This pump is amazing and a great value. Highly recommend,” writes 5-star reviewer Jennifer Boldman. “My husband giggles when he says, ‘This pump sucks but in the best way!'”
Pros
- Dual-float system safeguards against trigger failure
- Durable, coated cast-iron construction
- 1/2 HP motor
- Pumps up to 73 gallons per minute (GPM) and 4,400 GPH
Cons
- More complicated to use than single-float types

Best Battery-Backup Sump Pump
Zoeller Aquanot ProPak53
This Zoeller pump package isn’t cheap, as its a full preassembled sump setup including the same 1/2 HP Zoeller M53 Might-Mate pump we deemed our best overall pick. But the peace of mind provided by its battery-backup system makes it worth the investment. If a power outage or mechanical issue causes its primary AC pump to fail, this kit automatically switches over to a 12-volt battery that operates for up to 7 1/2 hours. A handy LED control panel identifies the current power status and an audible alarm alerts you when the backup pump is activated. This version also includes a three-year warranty.
Reviewer Stan gives it 5 stars, writing: “As soon as I installed the pump, it started raining. I intentionally let the well fill up to test the battery-backup pump, which worked flawlessly. Then I plugged the main pump in and it cycled continuously for days, as it rained hard all week. I have already recommended this system to three friends and family members.”
Pros
- Backup battery with alarm
- Comes pre-assembled and includes best overall Zoeller M53 Might-Mate pump
- Runs for up to 7 1/2 hours on battery
- Automatically switches back to AC power when power is restored
- Control box with LED screen
Cons
- 12v battery not included
- Pricey

Best Pedestal Sump Pump
Superior Pump 92551
Designed specifically to keep its motor cool during operation, Superio makes the best pedestal sump pump. A split capacitor regulates power consumption, large vent holes promote air cooling and its thermal overload protection automatically shuts down the pump if it’s in danger of overheating. This focus on pump longevity extends to the rest of the unit as well, which features a solid steel drive shaft and impeller, cast iron base and a stainless steel float ball. A 1/2-HP motor, five-bladed impeller and large intake ports work together to offer a 3,600 GPH capacity as well.
I ordered this after my old pedestal pump died during the power outage/basement flooding from Hurricane Irene, and it arrived in the middle of several days of heavy rain from the remnants of Hurricane/Tropical Storm Lee,” writes 5-star reviewer Michael J. Cashen. “It required less than 15 minutes of work to replace my old pump, and it easily handled the job and saved my sanity. It’s quiet—I’m so used to hearing my old noisy pump running that I initially went into the basement several times to check this one to make sure it was working.”
Pros
- Pedestal design intended not to overheat
- Handles liquids up to 180 degrees
- 1/2-HP motor moves up to 3,600 GPH
- Fully adjustable automatic switch
- Stainless construction built to last
- Easy to install and maintain
- Quiet
