Best OverallA dependable mid-size automatic sump pump with a debris resistant impeller, though buyers wanting maximum output should compare its 1/3 HP rating against a 1/2 HP pump before choosing.
A versatile manual utility pump for tight or flat surfaces, as long as you remember to unplug it yourself once the water is gone.
A dependable automatic pump for a residential sump pit, with a float switch and a power-check plug; the listing omits the discharge size, so confirm it against your pipe before ordering.
A cast iron half horsepower sump pump with a long cord, suited to replacing a worn pump in an existing pit. The listing does not state the switch type, so confirm it before you buy.
An automatic submersible sump pump rated at 3/10 HP with a cast iron housing, a float operated switch and a 115V LED lit power plug, built for basement water removal.
A low height automatic drain pump for residential drainage in tight, low spaces. Warranty and switch type are not described, so confirm them before installing.
A complete primary and battery backup sump package for a basement that must stay pumped through power outages. The backup battery is not named in the included parts, so plan to source one.
Popular PickA budget-friendly, portable utility pump, a solid pick for occasional cleanup jobs and less suited to permanent basement duty.
A higher-output pump for basements that see serious water volume, with the anti-airlock design and 5 year warranty as the standout details.
A tough cast iron sump pump for a basement pit that sees steady groundwater, with an automatic float and non-clogging impeller. The spec table lists no warranty, which is worth checking before buying.
A ready-to-drop-in primary and backup pump pair for basements that flood when storms knock out power. The required deep cycle battery is extra.
A cast iron automatic sump pump with a vertical float that fits narrow pits and replaces most pumps without replumbing. Warranty length differs on the listing, so confirm before buying.
A durable, higher output pump worth the price if the sump pit genuinely floods hard, given its cast iron build, tested float switch and 3-year warranty.
A sensible backup pump for a basement that cannot flood when the power fails, with a control panel that explains each warning. The battery is sold separately, so plan on buying one.
A portable dewatering pump for contractors and homeowners clearing flooded areas and excavations. It has no float switch listed, so it needs someone to start and stop it.
An automatic utility pump that starts and stops itself and clears water down to a thin film. Water must reach the start level before it kicks on, so shallow puddles need manual help.
A backup, not a replacement, best paired with an existing electric sump pump rather than bought as your only pump.
A straightforward cast iron workhorse for a standard sump pit, bought for reliability rather than flexible dewatering jobs.
A tidy, purpose-built solution for small-appliance drainage, with the caveat that you still need to buy the check valve and discharge pipe separately.
A preassembled primary and backup combo that most buyers install without a plumber, though its bundle of cords and floats can be a tight fit through a sump basin lid.

These 6 sump pumps are the most searched brands and models among the established products in this category (monthly searches for each brand and model); on a tie, the one with more owner ratings ranks first. Product data comes from public Amazon listings (updated 15 days ago). We do not test products ourselves.
Zoeller, Wayne, Tsurumi Pump, Liberty Pumps, Little Giant lead this category among the 10 brands that passed our curation checks.
A listing appears only when it has a recorded price, a minimum customer rating, and enough ratings or monthly sales. Generic and unbranded listings are left out, while every real brand stays, including brands sold only on Amazon. The ones that pass are ordered by how many people search for that brand and model each month; review counts only break ties.
Submersible sump pumps put the motor inside the pit below the water, while pedestal designs keep the motor above it, leaving an exposed assembly that needs clearance overhead. First decide how much water the pump must move through your discharge route: either format needs enough pumping capacity for the water entering the pit during heavy inflow, so replacing an undersized pump with a similar one can preserve the original problem.
Use flow at your installation’s required lift as the starting point. Among the 33 products that list flow rate, most fall between 21 and 85 gpm, and 46 gpm is typical. An advertised flow rate may describe pumping at little lift; delivery generally falls as the pump pushes water higher, and pipe friction reduces it further. Compare the manufacturer’s performance curve with the vertical rise to your discharge point and the resistance of your planned pipe run, including bends. Maximum lifting height is not a useful operating target because flow approaches zero at that limit. The horsepower filter cannot tell you whether a pump will handle your inflow through that route.
Automatic operation and outage protection are the next decisions. For unattended drainage, look for an automatic switch and compare its activation and shutoff levels with the water levels your pit can accommodate. A tethered float needs room to swing without catching the wall, pipe or another pump; a vertical float follows a more confined path but still needs unobstructed travel. If drainage must continue during a power cut, decide between battery backup and a water-powered arrangement where installation is permitted. Battery runtime varies with pumping frequency and battery condition; water-powered backup requires a suitable municipal water supply and consumes supply water while operating.
Before buying, compare the pump’s dimensions and required clearances with your pit opening, depth and cover, then confirm discharge connection compatibility and the electrical supply specified in the manual. For a backup arrangement, establish whether the battery, charger or required plumbing components are supplied or sold separately. Confirm the permitted debris size and liquid use; a sump pump should not be assumed suitable for sewage. Cast Iron and Plastic labels need a named component, such as the pump housing, and Stainless Steel in the color filter is not evidence of construction. Finish by checking access for clearing the intake and whether replacement switches are available.
