A sump pump is your first line of defense against basement flooding, groundwater intrusion, and costly water damage. The American Society of Home Inspectors estimates that over 60 percent of U.S. homes have wet basements — the right sump pump can be the difference between a dry basement and a repair bill in the thousands. This guide covers the top sump pump brands to consider, average costs, key features, pros and cons, and more.

Zoeller
- Average Cost: $250 to $900
Our Take
Zoeller is our top-rated sump pump brand because it is trusted by professional installers and is known for reliable, long-lasting performance. The M53 Mighty-Mate, made mostly from U.S. materials, is widely seen as the standard for residential use. Each cast-iron submersible pump is factory-tested by Zoeller to make sure it meets its performance standards before shipping. If you care more about quality and durability than initial price, Zoeller sets the standard.
The M53’s vertical float switch fits into narrow sump basins and avoids the sticking problems that can happen with tethered-float designs from other brands. One thing to note: the built-in snap-action float switch is rated for one million cycles, but it is usually the first part that needs replacing. Using the M53 with an external controller like the HydroCheck HC8000T can help the system last much longer.
Cost Information
Zoeller sump pumps typically cost $250 to $900, depending on capacity and motor size.
- 1/3 HP M53 Mighty-Mate: $250 to $350
- 1/2 HP Models: $350 to $500
- Battery Backup Systems: $600 to $900
Best Models
The Zoeller At Home 1/3 HP Cast Iron Submersible Sump Pump (model 1073-0001) moves up to 42 gallons per minute, features a non-clogging vortex impeller, and uses an electromagnetic float switch for reliable activation.
The M53 Mighty-Mate Submersible Pump is a 3/10 HP model with proven cast-iron housing and long motor life — ideal for most residential basements, rated to 2,580 gallons per hour at 0-foot lift and 2,040 GPH at 10 feet.
Liberty Pumps
- Average Cost: $250 to $850
Our Take
Liberty Pumps is a great choice if you want a durable cast-iron pump with app-based remote monitoring. This U.S. company offers the NightEye® wireless alarm system, a Wi-Fi add-on with no subscription fee. It sends real-time alerts by push notification, text, or email to up to four people when the pump turns on, loses power, or senses high water. This kind of remote monitoring is rare at this price.
The main drawback is that NightEye needs a working home Wi-Fi connection, and some users have reported occasional app issues after software updates.
Cost Information
Models range $250 to $850, depending on system type.
- Standard Submersible Pumps: $250 to $400
- Wi-Fi-Enabled Smart Pumps: $500 to $850
- Battery Backup Units: $300 to $600
Best Model
The Liberty Pumps 257 is a 1/3 HP cast-iron submersible pump rated for up to 50 gallons per minute. Paired with Liberty’s NightEye® wireless alarm (sold separately, no subscription fee), homeowners receive remote alerts for pump activation, power outages, and temperature drops — useful for vacation homes or homeowners who travel frequently.
Wayne Water Systems
- Average Cost: $200 to $800
Our Take
Wayne Water Systems stands out for offering high pump capacity with less noise than most brands at similar prices. The CDU980E, Wayne’s most popular model, can move up to 5,490 gallons per hour with its 3/4 HP motor. It uses upper and lower ball bearings in a sealed oil bath for very quiet operation and comes with a five-year warranty that covers all parts, including the motor and float switch. Assembled in the USA, its top-suction design means you don’t need to drill a weep hole during installation.
The brand’s rating is slightly lower because some units have float switch variability, but the warranty covers this. It’s something to keep in mind if you want a pump that needs no maintenance.
Cost Information
Typical Wayne pumps cost $200 to $800, depending on motor size and design.
- Submersible Pumps: $200 to $400
- Combination Primary + Backup Systems: $500 to $800
- Battery Backup Kits: $250 to $400
Best Model
The Wayne CDU980E 3/4 HP Submersible Pump moves up to 5,490 gallons per hour, features cast-iron and stainless steel construction, and is backed by a five-year limited warranty covering all parts. Its top-suction design filters debris and eliminates the need for a weep hole — installation typically takes about 15 minutes.
Groundworks
- Average Cost: $600 to $1,200 (installed)
Our Take
Groundworks is a good option if you want a sump pump system that is professionally installed and comes with a national warranty, instead of a do-it-yourself pump from a store. Their AquaStop™ Sump Pump System is available in single-pump, battery backup, and triple-pump setups, and is only installed by certified Groundworks contractors. It comes with a national transferable warranty.
The AquaStop™ Triple System combines a 1/3 HP primary pump, a 1/2 HP secondary pump, and a battery backup that can move over 11,500 gallons per hour, so it handles both heavy flooding and power outages. The 3.9 rating is due to higher costs compared to retail brands and the fact that service is only available in 33 states.
Cost Information
Installed systems typically cost $600 to $1,200, depending on configuration.
- Primary Pump Installation: $600 to $900
- Dual-Pump or Battery Backup Systems: $1,000 to $1,200
- Annual Maintenance Plans: $150 to $300
Best Model
The AquaStop™ Triple System combines three SafeDri™ pumps — a primary 1/3 HP pump for daily water removal, a secondary 1/2 HP pump for larger volumes, and a battery backup pump rated to discharge over 11,500 gallons per hour — with installation and warranty coverage handled by a single Groundworks contractor.
Flotec
- Average Cost: $150 to $450
Our Take
Flotec offers strong pumping power at a lower price. Its 1 HP high-output submersible pump can move up to 6,600 gallons per hour, which matches the performance of more expensive brands. Flotec, part of Pentair Water Systems since the 1990s, makes pumps with corrosion-resistant housings in thermoplastic, cast-iron, and zinc to fit different needs. It is a good choice for homes that need moderate to heavy use and want the best value for the money.
The 3.6 rating is because the warranty is shorter than premium brands and there are fewer built-in smart features, but these may not matter if you mainly care about performance and price.
Cost Information
Most models cost $150 to $450, depending on horsepower and build.
- Thermoplastic Submersible: $150 to $250
- Cast-Iron or Zinc High-Output (¾–1 HP): $300 to $450
- Optional Smart Controller Upgrades: $50 to $150
Best Model
The 1 HP High-Output Submersible Pump offers up to 6,600 GPH and optional monitoring add-ons for advanced flood prevention — one of the highest output-to-price ratios in this category.
The Basement Watchdog
- Average Cost: $300 to $900
Our Take
The Basement Watchdog is the most feature-packed backup pump in this guide, with over 35 years of experience in battery backup systems. The Big Dog CONNECT® model can move 3,500 gallons per hour at ground level and 2,200 gallons per hour at a 10-foot lift. Its microreed Dual Float Switch, a technology first introduced by Basement Watchdog, gives extra protection by activating the pump if one float fails.
The 3.5 rating is due to two main drawbacks: the Wi-Fi Module (BW-WiFi2) costs about $100 extra and is not included, and some users find setup and battery charger calibration tricky during heavy use. Still, for homes that often flood and lose power, the system’s features are worth these tradeoffs.
Cost Information
Installed setups typically cost $300 to $900, depending on configuration and optional upgrades.
- Primary Pump Only: $300 to $500
- Primary + Battery Backup System: $600 to $900
- Wi-Fi Module Add-On (BW-WiFi2): approximately $100 (sold separately)
Best Model
The Big Combo CONNECT® System (Model CITS-50) pairs a 1/2 HP cast-iron primary pump with a battery backup unit and 24/7 controller monitoring — with Wi-Fi remote alerts available via the separately purchased BW-WiFi2 module. Both pumps can run simultaneously for extra capacity during extreme flooding events.
Superior Pump
- Average Cost: $150 to $400
What We Love
Superior Pump is a good choice if you want reliable, simple water removal at a low price. Founded in 1999 in Minneapolis, Superior Pump designs its products in the U.S. with local engineering oversight. They offer both thermoplastic and cast-iron models in a wide range of horsepower. You can find their pumps at most major retailers, and they work well for light to moderate home use.
The 3.4 rating is because the warranty is shorter than some competitors and the thermoplastic parts wear out faster if used for heavy or constant pumping. It’s a solid value, but not meant for heavy-duty or flood-prone situations.
Cost Information
Most models cost $150 to $400, depending on horsepower and material.
- 1/3 HP Pumps: $150 to $250
- 1/2 HP Pumps: $200 to $350
- Battery Backup Systems: $300 to $400
Best Model
The Superior Pump 91250 1/4 HP Utility Pump is a widely available best-seller for light-duty water removal and emergency flood protection.
Little Giant
- Average Cost: $160 to $350
Our Take
Little Giant is designed for homes with shallow sump basins, tight crawl spaces, or low flooding risk where a full-size pump won’t fit. The Series 5.5 and Series 6 submersible models have 1-1/2 inch discharge ports and garden-hose adapters, so they fit in places where bigger pumps cannot.
The 3.0 rating is because these pumps are not made for heavy or constant flooding, do not have smart monitoring or battery backup on most models, and do not last as long under heavy use. For light-duty jobs in the right setting, they work well, but their use is limited.
Cost Information
Models typically cost $160 to $350, depending on size and motor strength.
- ¼ HP Compact Pumps: $160 to $220
- ⅓ HP Standard Pumps: $200 to $300
- Battery Backup Add-Ons: $300 to $350
Best Model
The Series 5.5 Submersible Pump delivers efficient performance in smaller basins and crawl spaces with limited clearance — one of the few residential sump pumps that offers a garden-hose-sized adapter for non-standard discharge.
