The Best Sump Pump Options


A good sump pump is invaluable in times of flooding or to prevent mildew. Sump pumps reside in a pit below the basement’s surface or sit on the basement floor. Once water reaches a certain level, the pump turns on and pumps water outside of the home and away from the home’s foundation.

We used sump pump reviews and user experience to examine the features and benefits sump pumps offer and select some of the top-rated sump pumps on the market. Each of the top picks underwent thorough product vetting to create the list below. Read on to learn more about what you should look for and some of the best sump pump options available.

The Best Sump Pumps


Types of Sump Pumps

When shopping for a new sump pump for your home, there are four main types to consider: submersible, pedestal, battery backup, and combination.


A submersible sump pump is designed to work in a pit called a sump basin, located below your basement floor’s surface. When water enters your basement, it flows into the pit. Once the water in the pit reaches a certain level, it triggers a sensor on the sump pump. The pump then turns on and begins pumping water out of your basement via a pipe running to the home’s exterior.

Since the pump sits in a sump basin, submersible pumps are quieter than other sub pumps and are out of the way of other activities that take place in the basement. Typically, they are more expensive than other sump pump types.

If you plan on going with a submersible pump, keep in mind you’ll need to have a sump pump basin dug in your basement floor, which can be an arduous and expensive endeavor.


Unlike submersible pumps, which live in a sump pump basin, pedestal pumps sit on the basement floor. They draw in water from the pump’s base and, like a submersible pump, pump the water through a pipe leading to a drainage area outside the home.

The pump’s motor, which is not waterproof, is located at the top of the unit. Pedestal pumps are less expensive than submersible pumps and don’t require the costly expense of digging a sump pump basin; however, the motor’s position on the unit’s exterior makes them noisier than submersible pumps.

Battery Backup

Pedestal and submersible sump pumps cannot work without electricity, which is significant given that flooding often occurs during storms that knock out power. A battery backup sump pump works similarly to a standard sump pump but uses a battery instead of an electric outlet for power. When a power outage sidelines your sump pump, the battery backup pump will step in to pump water out of the basement.

The average battery-powered sump pumps can pump up to 100 gallons of water on a single charge. Since battery life is limited, a battery backup will eventually give out during extended power outages.


The best sump pump brands include a built-in backup. These versatile units combine a standard electric sump pump with a battery backup, offering max protection for all flooding hazards. Combination pumps use a single pump and are more cost-effective than purchasing two separate pumps.

They also tend to be larger than standard submersible pumps, so if you have an existing sump pump basin, a combination unit may not fit. Check the minimum basin size requirements for the unit before you make a purchase.

What to Consider When Choosing the Best Sump Pump

Knowing the types of sump pumps that are out there is crucial, and it’s also important to understand the features to consider when choosing among the most reliable sump pump options including their materials, power capability, and ease of installation.

Basin Space

A standard sump pump basin is 30 inches deep by about 18 inches to 24 inches across, giving it a capacity of around 26 to 30 gallons. A smaller basin causes the unit to work harder, as it will fill more quickly, causing the unit to turn on more often. Different submersible sump pumps require different minimum basin sizes. Those sizes can vary significantly, ranging from 7 inches to 16 inches, so make sure you purchase a submersible pump that will fit the basin in your home.

Core Material

As with any motorized tool or appliance, durability is always an important factor to consider. Sump pumps are built with a surprisingly wide variety of materials. More affordable pumps are made with high-grade plastic that resists wear, while higher-end sump pumps feature stainless steel or heavy cast iron construction. Stainless steel has anti-corrosion properties, while cast iron maximizes cooling ability to better distribute heat from the motor.

The interior of a sump pump is just as important. Impellers, the fan-like mechanism that draws water into the pump, can be plastic or stainless steel, with the latter being the more durable of the two. The shaft that spins the impeller should be made of steel for long lasting functionality.

Power Source

Most sump pumps are electric-powered and feature 9-amp motors. Some energy-efficient sump pumps will operate at about half that amperage, saving you electricity and money. Battery backup sump pumps operate off of a 75-amp hour battery, which provides enough power to operate at a reduced pumping rate for a few hours before a recharge is needed. Combination sump pumps are electric-powered with a 75-amp battery backup that springs into action in a power outage.


Sump pumps range in power from 1/3 horsepower to 1 horsepower. The principle here is simple. The more powerful the motor, the more gallons of water per hour (GPH) the pump can remove. If you have a moderate to low accumulation of water in your basement, then a low flow 1/3-hp pump should suffice. However, if your basement is prone to flooding, it’s best to invest in a more powerful 1-hp sump pump.

No-Screen Intake

When a basement floods, it typically isn’t with crystal clear water. Usually, there is a fair amount of debris floating in it. The sump pump trying to keep your basement dry will inevitably suck that debris into it. Lower-end sump pump brands feature screens that filter out this material. That helps keep debris out of the impeller, but screens also eventually clog, reducing the pump’s ability to move water until you manually clean it.

Some pumps feature no-screen intakes that can process that solid material and eject it along with the water. These higher-end pumps are worth the additional investment if you have a basement that floods periodically.

Switch Type

The switch is the part of the pump that turns it on and off. Switch types fall into two categories: digital and manual. Manual pumps use a float that attaches to the switch. When the water rises, so does the float, which flips the switch, turning the pump on. When the water level drops, the float drops, and the switch turns off.

These floats can work on a tether that hangs next to the pump or on a vertical rod, which hangs below the pump. While these are effective for most homeowners, this type of switch can sometimes get hung up, especially if the pump basin is small, causing it to malfunction.

A digital switch is mounted vertically in the basin and features two sensors: an on sensor and an off sensor. When the water rises to a certain level, it triggers a sensor that turns the pump on until the water level drops to the off sensor, which shuts the pump off. Unlike manual sensors, which switch on or off based on one set level, a digital sensor allows the pump to run until it reaches the second sensor before switching off. This allows the pump to operate until the basin is nearly empty.


Some sump pumps will sound an audio alarm when the pump turns on, letting you know there is enough water accumulating in the basement to require its services. There are even high-end “smart” sump pumps that will text you when they switch on.

Additional Features

You need more than just the pump itself when setting up a sump pump in your basement. If you’re using a submersible sump pump, you’ll need a sump pump basin and cover to hold the pump. Basins come in various sizes, so make sure you know what size the sump pump you are purchasing requires.

You’ll also need a discharge hose that carries the water from the sump pump to an area outside your home that drains away from the house. If you’re purchasing a combo kit or battery backup unit, you will need to buy a battery for the unit. Sump pumps typically run off of 75-amp hour batteries.

If you have lingering concerns about sump pumps, read on for the most common questions.

Q: Where should the extra water be drained by a sump pump?

Sump pumps use a drain hose to remove water from your basement. A drain hose should extend outside of your home to an area on your property that drains away from your house. This is crucial. You don’t want the water you just pumped out to run back into your basement, starting the cycle all over again.

Q: How often does a sump pump need to be cleaned?

You should clean your sump pump once a year. That said, when your pump tackles an especially hard job, such as removing water from a flooded basement after a bad storm, you should clean it as soon as possible.

Q: How often should you replace sump pumps?

On average, sump pumps last about 10 years. Keep tabs on older units as you likely won’t notice it’s no longer working until water is accumulating in your basement.
