For most homeowners dealing with a wet basement or a yard that floods after heavy rain, the WAYNE CDU980E is the sump pump to buy: a 3/4 HP cast iron and stainless steel unit rated for 5,490 gallons per hour with a vertical float switch that resists jamming in narrow pits. If the power tends to go out during storms, pair it (or replace it) with a battery backup system so the pit keeps draining when it matters most.
Quick answer: the WAYNE CDU980E is the best all-around sump pump for 2026. If your area loses power during storms, add a battery backup unit like the WAYNE WSS30V so the pump keeps running when you need it most.

Our top picks reviewed
1. WAYNE CDU980E: Best overall
WAYNE CDU980E 3/4 HP Submersible Sump Pump
The CDU980E pairs a cast iron pump housing with a stainless steel outer shell, a combination that documented product testing and long-running user feedback consistently point to as more durable than the all-plastic pumps in this category. Its integrated vertical float switch takes up less room than a tethered float, which matters in a standard 18-inch sump basin. At a rated 5,490 GPH, it has enough headroom for yards with heavy clay soil or a high water table, and the 3/4 HP motor is specced for continuous duty rather than intermittent use.
Pros
- Cast iron and stainless steel construction rated for long service life
- Vertical float switch fits narrow sump pits without snagging
- High 5,490 GPH capacity handles heavy inflow
- 5-year manufacturer warranty
Cons
- Larger and heavier than plastic utility pumps
- No battery backup included
- Runs louder than smaller thermoplastic models
2. WAYNE WSS30V: Best for power outages
WAYNE WSS30V 1/2 HP Sump Pump with Battery Back Up Capability
Basements flood most often during the exact storms that also knock out power, which is why a primary pump alone is not a complete plan. The WSS30V ships pre-assembled with a 1/2 HP primary pump and a 12V battery back-up circuit built into the same unit, so it drops into a 16-inch or larger basin without a separate secondary pump taking up space. Documentation lists a battery capacity of up to 10,000 gallons removed on a single charge, which is generally enough to cover a multi-hour outage. Note that the battery itself is sold separately.
Pros
- Primary pump and battery backup in one pre-assembled unit
- Installs in a standard 16-inch or larger basin in minutes
- Up to 10,000 gallons of backup capacity per charge
- 3-year warranty, assembled in the USA
Cons
- Battery sold separately, adding to the real cost
- 1/2 HP primary is lower capacity than dedicated single-purpose pumps
- Battery needs periodic maintenance to stay reliable
3. Zoeller M53: Best for tight sump pits
Zoeller M53 Mighty-Mate Submersible Sump Pump, 1/3 HP
The M53's cast iron housing and compact footprint have made it one of the most specified pumps in new residential construction for decades, and it remains a common recommendation from plumbers for smaller sump pits where a bulkier pump will not sit flat. Its snap-action float switch is simple and largely maintenance-free, and Zoeller states every unit is factory tested in water before it ships. The 1/3 HP motor trades some raw capacity for a smaller, quieter package.
4. Superior Pump 91250: Best budget pick
Superior Pump 91250 1/4 HP Thermoplastic Submersible Utility Pump
This is technically a utility pump rather than a dedicated sump pump, and it is sold without a float switch, so it will not run unattended in a sump pit the way the other picks here do. Where it earns its place is as an affordable way to clear standing water from a flooded yard low spot, window well, or after emptying a kiddie pool: a 10-foot cord, garden hose adapter, and a rated 1,800 GPH cover most small cleanup jobs for a fraction of the price of a dedicated sump system.
5. Basement Watchdog BWE: Best all-in-one backup system
The Basement Watchdog Emergency Battery Backup Sump Pump System (BWE)
Rather than modifying an existing primary pump setup, the BWE is designed to sit alongside your current sump pump as a dedicated backup that only activates if the primary fails or the power goes out. Its copper-wound motor is rated by the manufacturer for a longer service life than the aluminum-wound motors found in some competing backups, and the system includes an alarm that alerts you the moment the backup takes over, which is often the first sign of a problem with the primary pump.
How to choose a sump pump
Match the pump's horsepower and GPH rating to your situation rather than buying the biggest number on the shelf. A 1/3 HP pump is enough for most residential basements with a moderate water table, while 1/2 HP and 3/4 HP units are better suited to yards with heavy clay soil, a high water table, or a history of serious flooding. Check your sump basin's diameter before choosing between a vertical and tethered float switch: vertical switches save space in narrower 16 to 18-inch basins.
Battery backup is worth the extra cost if storms in your area regularly cause power outages, since that is precisely when a sump pump is needed most. A backup system can either be integrated into the primary pump, like the WSS30V, or run as a separate unit that only kicks in when needed, like the Basement Watchdog BWE. Either approach beats having no backup at all.
Finally, plan for the accessories that make a pump actually work as a system: a check valve to stop water flowing back into the pit between cycles, rigid or flexible discharge pipe routed away from the foundation, and, ideally, a water sensor alarm as a second layer of warning if the pump can't keep up.

FAQ
How often should I test my sump pump?
Most manufacturers and plumbers recommend testing a sump pump every three to four months, and always before the start of a rainy season. Pour a bucket of water into the pit and confirm the float switch triggers the pump and the water drains normally.
Do I need a battery backup sump pump?
A battery backup is strongly recommended if your area experiences power outages during storms, since that is when flooding risk is highest and a mains-powered pump alone will not run. Even homes on a well-maintained grid can benefit from the extra layer of protection.
What size sump pump do I need for my basement?
For most homes, a 1/3 HP to 1/2 HP pump with a rated capacity in the 2,000 to 5,000 GPH range is sufficient. Homes with a high water table, heavy clay soil, or a history of severe flooding should size up to a 3/4 HP or larger pump.
Can a sump pump help with yard drainage as well as basement flooding?
A submersible sump or utility pump can clear standing water from a yard low spot, window well, or after a heavy storm, though a dedicated sump pump installed in a basin is the correct long-term solution for a basement, while a portable utility pump is better suited to occasional yard cleanup.
