Bottom line: The Wayne CDU980E offers power and durability

Sump pumps can help save your basement from water damage. That means you’re also free of the clean-up nightmare that comes with throwing out ruined furniture, tearing out moldy walls to rebuild, and filing insurance claims. They’re a relatively small investment compared to the value of your home and belongings but make a big difference in flood-prone basements.

What is a sump pump?

Sump pumps remove excess water from basements in areas where flooding regularly happens. This may be due to heavy rains or a high water table. They reduce the likelihood of water damage ruining your home and possessions.

Most sump pumps sit in a sump basin or pit below the basement floor, allowing the pump to function before water levels enter your home.

Time and again, our research pointed to the Wayne CDU980E as the best sump pump for most houses. It has a durable cast iron and stainless steel construction that stands up to the water it pumps by protecting the motor. The powerful 3/4 horsepower (hp) motor can pump an overwhelming amount of water to keep your basement dry but makes it one of the more expensive options on our list. Overall, we think it’s a prudent choice that balances features and price.

About flow rate and vertical lift

Flow rate is one of the most important aspects of a pump. It measures how much water a pump can move in gallons per hour (GPH). But the pump’s performance changes as the vertical lift (pump head) increases, so we listed two numbers for different lifts in our table above. To learn more about vertical lift and flow rate, check out our FAQ: What is pump head?

Our approach

To find the best sump pumps, we spent 24 hours researching information from manufacturers, online reviews, plumbers, and sump pump specialists. We considered 20 products from 11 different manufacturers, ultimately narrowing down our list to our top five with five honorable mentions.

With one exception, we ignored high-performance sump pumps that cost over $200, though many of the brands in our review sell more expensive models for situations that require a higher flow rate or greater vertical lift.

Based on our research, we primarily chose and recommended submersible sump pumps with 1/3 hp motors or higher. We also mention battery-backup and pedestal-type pumps for folks that want alternative options. To learn more about how we review and rank products, check out our full methodology.

About horsepower

Horsepower is a measure of a motor's power, or its ability to move things. It affects anything that uses a motor, like cars, vacuum cleaners, and sump pumps. By installing a sump with higher horsepower, you can pump more water than a model with low horsepower.

Sump pump reviews

1. Wayne CDU980E: Best overall

Wayne CDU980E sump pump

Wayne CDU980E

The Wayne CDU980E consistently ranks among the top sump pumps in online reviews, and it’s easy to see why. This pump comes with a powerful 3/4 hp motor that moves up to 5,490 gallons per hour (GPH), which is more than other pumps we researched, including several more expensive models.

It’s a submersible sump pump, making it quieter than pedestal-type pumps. This is useful if you spend a lot of time in your basement and don’t want a noisy pump to interrupt your movies and projects.

Durability is another standout feature of the Wayne CDU980E. It has a cast iron and stainless steel body that protects the internal motor from water damage. Wayne is confident enough in this design that the pump has a five-year warranty, the longest warranty among sump pumps.

Because this submersible pump rests in the bottom of a sump pit, it’s harder to reach for regular maintenance than a pedestal pump. This isn’t enough of an inconvenience for most folks but matters if you have trouble bending down or laying on the floor for occasional debris removal.

The Wayne CDU980E costs around $150, making it more expensive than most competitors we looked at. Still, we think the powerful motor and durable design are worth the extra cash.

Pros

  • Quiet operation
  • Stainless steel and cast iron construction
  • Powerful 3/4 hp motor
  • Five-year warranty

Cons

  • Relatively expensive
  • Harder to maintain than pedestal pumps

Decades of experience

The Wayne company has over 70 years of experience making water pumps, making it one of the most experienced companies we reviewed. The company takes its name from Fort Wayne, Indiana, where it operated for the first 63 years of its existence.

2. Superior 92250: Best value

Superior 92250 sump pump

Superior 92250

Superior Pump touts 20+ years of experience, making some of the most affordable sump pumps on the market. Our favorite pump from this company is the Superior 92250 because it costs around $55—almost one-third the price of our top pick from Wayne.

We chose this pump because it’s an upgraded version of the popular Superior 91250. The main difference is that the 92250 has an automatic switch, so you don’t have to activate it manually when water starts to build up. It’s around $10 more expensive, but the automatic operation is worth every penny.

This sump pump doesn’t have a particularly powerful motor, only 1/4 hp, but moves up to 1,800 GPH. This is almost as much water per dollar as more expensive pumps. We also like that this unit has a small size that’s easy to move and lift out of the sump basin for maintenance.

Unfortunately, the sump pump’s light frame comes from a plastic construction that isn’t as durable as the metal casings on other brands. You might replace this more often than an expensive model, but it’s an excellent option to save money for other home improvements.

Pros

  • Affordable
  • Light, compact size
  • Automatic power switch

Cons

  • Plastic construction
  • Low horsepower

3. Wayne WSS30V: Best battery backup

Wayne WSS30VN sump pump

Wayne WSS30VN

The Wayne WSS30VN is actually a bundle of two pumps: a main pump and a backup pump. Together these pumps allow you to have flood protection, even when the power goes out. You can buy the battery backup pump separately, but we wanted to highlight that battery backup pumps aren’t a stand-alone solution.

Most battery backup pumps don’t offer a high flow rate to pump water and last only as long as the battery does. Essentially, you’re paying for redundancy to keep water out of your basement when the primary sump pump loses power. Like other submersible sump pumps, you can expect quiet operation from the Wayne WSS30VN. The primary pump has a powerful 1/2 hp motor that can move up to 5,100 GPH, almost as much as our top pick, the Wayne CDU980E.

For such an expensive bundle, it doesn’t come with some vital components like a battery and a check valve. The check valve is usually a separate $10–$30 purchase for sump pump installations, but buying a battery for the backup pump adds around $275 to the overall cost. This is a big detractor if you want to save money.

What is a check valve?

A check valve is a one-way valve between your sump pump system and the discharge pipe. It keeps leftover water from flowing back into your home after the pump turns off.

Even though the backup sump pump is a nice feature, it’s unnecessary unless your house has a history of simultaneous power outages and flooding. Still, if you must have a battery backup, we think the Wayne WSS30V is an excellent option.

Pros

  • Comes with a primary and backup sump
  • Battery backup during power outages
  • Quiet operation

Cons

  • Expensive
  • Battery sold separately

4. Superior 92551: Best pedestal pump

Superior 92551 sump pump

Superior 92551

The Superior 92551 has a different design than other pumps on our list. Its motor rests on a pedestal at the top of a tall shaft—not at the bottom of a sump basin like a submersible pump. This keeps the motor far from the water below, which results in a longer-lasting pump design. It qualifies for a five-year warranty because its electrical components have less exposure to water.

Because the motor is above floor level, it’s easy to adjust the float switch that turns on the unit and makes it easier to look for motor problems. You still need to clean out the sump basin as debris builds up, but it’s less of a hassle when your motor casing doesn’t have gunk all over it.

The 1/2 hp motor on this pedestal sump pump isn’t as powerful as it would be on a submersible pump, but it has an excellent output of up to 3,600 GPH to keep your basement dry. Since the motor isn’t down in a sump pit, it’s noisier than submersible models, but the noise isn’t a problem if your pump doesn’t run very often.

While we prefer submersible pumps for their power, the easier maintenance of this pedestal pump makes it a useful alternative for folks with limited mobility.

Pros

  • Easy to maintain
  • Long warranty
  • Powerful 1/2 hp motor

Cons

  • Noisy operation

5. AmazonCommercial AB-P100: Affordable power

AmazonCommercial AB-P100 sump pump

AmazonCommercial AB-P100

Amazon is a fairly recent entrant in the sump pump market with its AmazonCommercial line of products.

In general, the company has an excellent reputation for customer service, and its white-label AmazonBasics products are surprisingly effective, given their lower prices. The AmazonCommercial AB-P100 is a superb example because it offers a high flow rate for an affordable price.

This submersible unit can pump up 3,060 GPH thanks to a 1/3 hp motor, making it an excellent intermediate pick between the ultra-cheap Superior 92250 and the high-flow Wayne CDU980E. The motor also has an impressive vertical lift of 29 feet, which means it can pump water higher than any other pump on our list.

About vertical lift

Even though this pump has a high vertical lift, the amount of water it can pump at that height is very low. In general, we don’t recommend pumping water much higher than 20 feet with this pump to get a flow rate of at least 1,740 GPH.

One of the reasons this pump is so affordable is because its plastic body isn’t as durable as steel or cast iron. Still, Amazon sells more powerful cast iron and stainless steel variants for about $25 more if you want something more robust. All of these pumps have a one-year warranty, which isn’t as long as the five-year coverage you get with more established products like the Wayne CDU980E.

In any case, we think Amazon crafted a solid product that provides excellent performance for a relatively low price.

Pros

  • High flow rate
  • More affordable than similar products
  • Vertical lift up to 29 feet

Cons

  • Plastic construction
  • Short warranty

More sump pumps we considered

Liberty Pumps 257

The Liberty Pumps 257 (about $198) is more expensive than our top pick, the Wayne CDU980E, but doesn’t quite match the flow rate. Even though it’s less powerful, this pump can handle solid particles up to 0.5 inches, something that our top pick can’t do. This makes Liberty Pumps suitable for moving dirty water with lots of debris.

Zoeller M53

Zoeller has roots in 1939, making it the oldest company we looked at for our review. The Zoeller M53 (about $175) is similar to the Liberty Pumps 257 because it can also handle solids up to 0.5 inches, making it a heavy-duty alternative to typical home sump pumps.

Final word

A flooded basement is expensive and frustrating, but you can prevent it with a reliable sump pump like the Wayne CDU980E. It has a solid design of cast iron and stainless steel that protects its powerful motor from corrosion. Speaking of powerful motors, it outperforms the competition by a healthy margin, making it quite capable of protecting your basement.

Sump pump FAQ

Do all basements need a sump pump?

You need a sump pump if your home meets certain requirements:

  • Past water damage and basement flooding
  • Poor soil drainage after storms
  • High groundwater levels in your area

If your home already has an old sump pump, consider replacing it with a newer model. During our research, we found that most manufacturers and plumbers recommend replacing your sump pump every 5–10 years, depending on the quality of the pump.

Plan to replace your pump on the same schedule, especially if you have a newer home or know the pump installation date. If you don’t know how old your pump is, you can replace it without spending a lot of money.

For homes that need sump pumps but don’t have them, you probably need to hire a professional to install the pump.

Where do sump pumps discharge?

The machine pumps water up a pipe that drains outside your home. Depending on your property and the local building regulations, the pipe might drain directly onto your lawn, go under your lawn, or into a storm drain. Do not attach a discharge to a storm drain without checking with your local government.

What is pump head, and why does it matter?

The pump head (or vertical lift) is how high a pump can move water before it stops working. If the discharge pipe is higher than the pump head, water will continue to accumulate in your basement instead of going through the pump.

Pump head matters because the pump’s flow rate decreases as you pump the water higher. Most sump pumps don’t need to pump water more than 5 to 10 feet higher than your basement floor. But more powerful pumps guarantee a flow rate that keeps up with the water accumulation in your basement.

Do sump pumps smell?

Sump pumps can cause smelly basements if standing water sits in the sump basin long enough for microorganisms to grow. During the wet season, the water moving through the basin will prevent smells, but you might need to clean the basin occasionally during drier times.

A strong water/bleach mixture (1 cup of bleach to 1 gallon of water) is usually enough to kill bacteria and eliminate undesirable smells. If the smell doesn’t go away, you may need to scrub the sump basin.

In general, there should always be a little water in the bottom of the basin to help prevent stinky gases from coming in through the discharge pipe.

What is better, pedestal or submersible sump pumps?

In general, we recommend submersible sump pumps for their power and quieter operation, but there are pros and cons to each type of sump pump:

Submersible prosPedestal pros
  • More powerful
  • Handles solid particles better*
  • Quieter operation
  • Easier to maintain
  • Longer lifespan
  • Generally more affordable
  • *Solid particles aren’t usually an issue in a properly-maintained home sump basin but tend to occur more frequently in agricultural and industrial settings.

    Can you add battery backup to an existing sump pump?

    Yes, many brands sell battery backup pumps that sit next to an existing sump pump. The backup pump isn’t very powerful and doesn’t replace your existing pump.

    It removes water when the power goes out but eventually stops when the battery dies. Only a primary pump with an uninterrupted power supply can keep pumping in the long term.

    Water-powered sump pumps

    There’s a special type of sump pump that doesn’t require electricity to run but uses water pressure instead. Water-powered sump pumps are ideal for long-term water disposal without electricity, but they can add to your water bill.

    Who installs sump pumps?

    If your home doesn’t have the correct sump pump infrastructure in place, you need to hire a contractor, plumber, or sump pump specialist (basement waterproofers). They’ll cut through your basement’s concrete floor to install a sump basin before setting up the pump, valves, and discharge pipes.

    You also need an electrician to install a ground-fault circuit interrupter (GFCI) outlet to prevent water from creating an electrical hazard. GFCI outlets cut the power if they detect a problem with the electrical circuit, like exposure to water.

    Replacing an existing sump pump is an intermediate DIY project you can do in a couple of hours if you don’t want to hire an outside contractor.
