What Customers Are Saying

Customers we found were extremely pleased with this sump pump’s value as well as its ease of use. Others also complimented how quickly it worked, as well as its ability to drain a large amount of water. However, there were some complaints about lack of clear instructions, while others found that it slowed down the longer it was running.

Types of Sump Pumps

Our research indicates that there are four main types of sump pumps: submersible, pedestal, battery backup, and combination.

Submersible Pumps

Submersible sump pumps are wholly submerged in the pit, or sump basin, below your basement’s floor. Once the pit fills with a certain amount of water, it triggers the pump’s sensor, which turns the pump on and starts the water removal process.

This type of sump pump is typically quieter than other types of sump pumps because its motor is inside the pump, but it’s more expensive than other pumps.

Pedestal Pumps

Pedestal sump pumps sit in a basin that’s level with your basement floor and remove water through a pipe that leads to a drainage area in your yard.

They’re more affordable than submersible sump pumps, but their motor is attached to the outside of the device, making them noisier.

Battery Backup Pumps

Unlike submersible and pedestal models that run solely on electricity through a power cord, battery backup sump pumps have a battery-powered backup pump that kicks on when the main unit can’t run due to a power outage.

The battery on the backup pump can typically last for a few hours on a single charge. While this is enough for short surges, the battery will eventually die if it’s pumping a lot of water during an hours-long outage.

Combination Pumps

Combination sump pumps include the power cord of pedestal and submersible models and the backup battery of battery models, allowing them to work in all situations. They usually sit in a below-the-floor basin like submersible sump pumps, but they’re larger, which means you can’t use the basin you dug for your old submersible sump pump for your new combination sump pump.

Sump Pump Buying Guide

Before purchasing and installing a sump pump, it’s important to understand how each model’s design and specifications impact its performance. Here are a few factors we found that are most critical when buying a sump pump.

Power Source

Most sump pumps are powered by electricity, but some models include a battery backup that powers the device in case of a blackout. For example, we noted that some pumps include a battery that can pump thousands of gallons on a single charge. Models that don’t have a battery backup can pump thousands of gallons of water per hour as long as electricity is available.

Horsepower

The horsepower (HP) of a sump pump’s motor refers to its overall power, with a higher HP motor being able to pump more water per hour than a lower HP motor. Many sump pumps that our team researched contain ½-HP or ⅓-HP engines, though some models contain more powerful ¾-HP engines. While higher HP motors can pump more water per hour, they’re typically more expensive.

Sump Pump Switches

Most sump pumps use either a digital or manual switch to start their motors. Manual models contain floats that rise with the flood water, turning on the pumps when the water reaches a certain level. When the floats dip below the set level, the pump stops.

Other models feature a set of digital sensors. The pump starts working when the water rises to meet the “on” sensor. The pump turns off once the water lowers and reaches the “off” sensor. The benefit of digital switches is that they continue pumping water until they reach the off sensor, even if the water level dips below the on sensor.

Alerts

Many sump pumps we examined come with audible alarms that signal rising water levels in your home.

Material Composition

We found that sump pumps are usually made of plastic or metal, such as aluminum, stainless steel, or cast iron.

Plastic sump pumps are more affordable but not as durable as metal sump pumps.

Installation

While leaving it to a professional may be preferable for some, DIYers may also want to install the sump pump themselves. For step-by-step instructions on how to properly install a sump pump in your home, check out the video below.

Sump Pump FAQ

What’s the purpose of a sump pump?

A sump pump is typically placed in a basement to prevent damage brought on by significant basement flooding and give you added peace of mind. It detects rising water levels, pumps that water out of your basement, and directs it away from your home.

Does my sump pump require regular maintenance?

To ensure that your sump pump functions properly, we recommend cleaning its components at least every three months by following these steps:

  • Disconnect the pump from the wall outlet or battery.
  • Disconnect the pump’s discharge pipe.
  • Bring the pump to your yard.
  • Scrape off the grime with a sponge or cloth.
  • If there’s too much grime to remove by hand, use a standard garden hose to blast it off.
  • Disinfect the pump and its basin by wiping them with bleach, vinegar, or another disinfectant.
  • Use a shop vac to clean the remaining debris and water from the basin.
  • Reconnect the pump.

Where do sump pumps discharge water?

Most sump pumps send the excess water into a storm drain or dry well.

Do sump pumps smell?

We have found that sump pumps can develop an odor if they haven’t been used in a while. Infrequent use causes the water in the pump’s basin to dry fully, releasing smelly gases into the air. Mold and bacteria growth inside the pump and the basin can also cause a smell.

One step we recommend to eliminate these odors is to create a solution with a ratio of 1 cup of bleach to every 1 gallon of water. Pour this solution into the basin until the pump is activated. To prevent an odor from developing in the future, wash your sump pump regularly and keep the basin full of enough fresh water to cover the drain lines.

How We Selected the Best Sump Pumps

To provide our readers with the best sump pump recommendations possible, we rely on several key sources of information to help guide our selection process.

Initial Research: Our research process began by generating a list of pumps with a significant number of verified-buyer reviews and an average customer review rating of 4–5 stars. We looked at positive and negative reviews alike, focusing on information from both satisfied and critical buyers.

Expert Insights: Through our years of experience, we’ve learned that listening to what others have to say is critical to building accurate, well-rounded articles. To complement our in-house expertise, our team looked at reviews and videos from trusted publications and independent testers, spoke with subject matter experts, and drew insights from reader contributions.

Final Product Selection: We then began fine-tuning our list by replacing older models with the latest versions and eliminating any discontinued models.
