Pools & Pumps · Best-of list
The best sump pump for your basement is one that fits your pit, pushes water as high as your pipe climbs, and has a switch that suits the pit's size. This list shows primary pumps whose makers state both the flow (GPH) and the switch type, highest stated flow first, at most two per brand. Every number is as the listing gives it. I'm Dell Pruitt, and I read the data plate before I read the box. Ana says I'd read the plate on a toaster. I have.
How this list is builtPrimary sump pumps whose maker states the flow (GPH) and the switch type, highest stated flow first, at most two per brand and four per horsepower size. Flow is compared only as the maker lists it.

Good for a 1/2 HP cast iron pump with the highest flow stated in this list, 6,900 GPH as the listing gives it, a 20 ft maximum lift and a 2-inch discharge.
Skip it if you want a pump sold only for clear groundwater; the listing also calls it a sewage and effluent pump for septic tanks, and its tethered float needs room to swing in your pit.
Good for a tall lift. The listing states 3/4 HP, 6,480 GPH, the highest maximum head in this list at 37 ft, a vertical float and a cast iron housing.
Skip it if your pit fills slowly and a smaller pump keeps up; NDSU Extension says a larger pump gives no advantage there. Our data doesn't state its discharge size.
Good for a pit that fills fast and needs a bigger motor. The listing states 1 HP, 6,100 GPH, a vertical float, a cast iron housing and a 1-1/2 inch discharge.
Skip it if you want to compare maximum lift; the listing in our data doesn't state a maximum head, so check the maker's chart before you buy.
Good for the biggest motor in this list. The listing states 1.5 HP, 6,000 GPH, a 33 ft maximum head, a vertical float and a cast iron and steel housing.
Skip it if your pit fills slowly; NDSU Extension says a 1/3 HP pump suits most houses, and this is far more motor than most pits ask for.
Good for a mid-size pump with a tall stated lift. The listing states 3/4 HP, 5,500 GPH, a 32 ft maximum head, a vertical float and a cast iron and stainless steel housing.
Skip it if you need to match a discharge pipe size before you order; our data doesn't state the discharge size.
Good for a 3/4 HP pump in a narrow pit. The listing states 5,490 GPH, a vertical float, which rides on a rod beside the pump, and a cast iron housing.
Skip it if you want a stated maximum lift to compare against your own; the listing in our data doesn't give one.
Good for a 1/2 HP cast iron pump with a tethered float in a wide pit. The listing states 4,860 GPH, a 30 ft maximum head and a 10 ft power cord.
Skip it if your pit is narrow, because a tethered float needs room to swing, or if you want a pump sold only for clear water; the listing also names sewage and wastewater.
Good for a 3/4 HP pump with a stated safety listing. The listing states UL listed, 4,800 GPH, a 25 ft maximum head, a vertical float, a cast iron housing and a 2-inch discharge.
Skip it if your discharge pipe is a different size and you'd rather not change fittings; read the manual's piping notes first.
Good for a 1/2 HP primary pump for an average pit. The listing states 4,300 GPH, a vertical float and a cast iron housing.
Skip it if you want a stated maximum lift; the listing in our data doesn't give one, so check the maker's flow chart against the height your pipe climbs.
Good for someone setting up a primary pump and a backup at once. The listing calls it a primary + backup combo and states 1/2 HP, 4,200 GPH, a 25 ft maximum head, a vertical float and a cast iron housing.
Skip it if you already have a backup or an alarm in place and only need to replace the primary pump.
Good for a pit that fills slowly, where NDSU Extension says 1/3 HP suits most houses. The listing states 1/3 HP, 3,200 GPH, a 25 ft maximum head and a vertical float.
Skip it if you want to know the pump style and housing material up front; our data doesn't state either for this model.
Good for a 1/3 HP submersible pump for a pit that fills slowly. The listing states 3,200 GPH, a 25 ft maximum head, a vertical float and a 1-1/2 inch discharge.
Skip it if your pit fills fast enough that a 1/3 HP pump would run without a break; NDSU says a 1/2 HP pump may keep up where a 1/3 HP may not.
The rule is short. A pump makes the list if it's a primary sump pump and its maker states two things: the flow in gallons per hour (GPH) and the switch type. Then the list runs from the highest stated flow down.
Two caps keep it from turning into one brand's catalog. No brand gets more than two spots, and no horsepower size gets more than four. Two per brand, and nobody past two. Nobody gets a third helping at Sunday dinner either.
A few things the list doesn't do:
The data date for this list is 2026-10-31. Listings change, so the table updates as they do. The sump pumps page shows every live model; the notes under this table follow the same order and give one fit and one trade-off for each pump, taken from the listing.
Sump pump listings pile on words. The table keeps the numbers that decide whether a pump fits your basement:
A dash in the table means neither the maker nor the listing states that value. A dash isn't a bad mark. It's a question to answer from the manual before you buy.
Here's the thing about GPH. A single flow number in a listing title rarely says how high the pump was pushing when it moved that much water. Lift, also called head, is how high the pump raises the water, from the pit up to where the pipe leaves the house. Flow drops as lift rises.
NDSU Extension explains that most new sump pumps come with a chart or graph, in the instructions or on the box, showing flow against height of lift. One maker's spec page for a 1/2 HP pump shows how much that matters: a maximum capacity of 6,000 GPH, and 4,140 GPH at 10 feet of lift.
So the order in this list is the order of the numbers makers put up front. It isn't the order the pumps will run in your basement. To compare two pumps fairly, find each one's flow at your lift on the maker's chart, in the same unit.
A GPH number with no lift next to it is like a speedometer that only shows top speed, measured downhill.
Four things decide it, in this order: how fast your pit fills, how high the water has to climb, how wide the pit is, and what happens when the power goes out.
NDSU Extension says there's no single correct size. The drainage area that feeds the pit, the depth to groundwater and the depth of the basement all play into it. Its baseline: a 1/3 HP pump is satisfactory for most houses. The City of Edmonton's buying checklist sets the same floor, a minimum of 1/3 HP.
The case for the best 1/2 HP sump pump is a pit that fills fast. NDSU says that in similar conditions a 1/2 HP pump moves more water and lifts it higher than a 1/3 HP pump. It also says that where water comes into the pit slowly, the larger pump has no advantage. Where the flow can turn rapid, the 1/2 HP pump may keep up where the 1/3 HP may not.
Watch your pit through one hard rain before you decide. The sump pump sizing guide walks through it. If it fills slowly and the pump rests between runs, a 1/3 HP pump is a fair starting point. If it fills fast and the pump barely gets ahead, look at 1/2 HP and up.
Every pump here lists one of two switches.
A tethered float needs room to swing without touching the pit wall. The maker spec page above lists a 14-inch minimum sump diameter for its tethered-switch pump. A vertical float stays close to the pump body. Before you order, measure your pit's width, then find the minimum basin size in the manual of the pump you're looking at.
Most pumps in this list have a vertical float. The ones with a tethered float are noted in the pick notes.
Measure from the water level where the pump turns on up to where the discharge pipe leaves the house. Edmonton's checklist describes pump head as the distance from the sump level to the pipe's exit, and puts its minimum at about 10 to 12 feet. It counts the distance the water travels, too, so a long run across the yard adds to the job.
The listed max head is where the flow stops. A pump at its max head is working hard and moving little. Pick one whose max head sits well above your measured lift, then read the flow at your lift on the chart. Where a listing in this list doesn't state a max head, the table shows a dash.
Edmonton's guide calls for a 1 1/4-inch discharge line. The pumps here that state a discharge size list 1-1/2 inch or 2 inch. Check your existing pipe before you order, and fit the pump the way its manual shows.
If you're hunting for the best cast iron sump pump, most of this list qualifies on paper. Most listings state a cast iron housing, a few with steel or stainless steel added. Where a listing doesn't state a housing material, the table shows a dash. We don't rank by material, because none of the sources we read compares how housings hold up over time.
None of these listings gives a noise level in decibels, so there's no fair way to name the best quiet sump pump by number. Community Association Underwriters of America, an insurer, says submersible pumps are much quieter than pedestal pumps, whose motors stand above the pit. Every listing here that states a pump style says submersible, apart from the one sold as a primary and backup combo.
My one opinion on this page: a battery backup or a high-water alarm is part of a sump setup, not an extra. The reason is in the City of Ann Arbor's list of why primary pumps fail. Loss of power comes first, from a blackout, a blown fuse, a tripped breaker, a damaged cord or a pump that's been unplugged. A stuck float, a burned-out pump, a clog, a failed check valve, a blocked pipe and more water than the pump can handle round it out. Many of those show up during storms, which is when the pump is needed.
Ann Arbor is fair about it. It says not everyone needs a backup, that backups add expense, maintenance and complexity, and that your own risk decides it. Its questions are worth a minute: do you lose power often, has the basement flooded before, and how often are you home to check?
The backup choices, as Community Association Underwriters of America and Ann Arbor describe them:
A pump listed as a primary and backup combo carries that note in the table. For the rest, the battery backup sump pumps and sump pump alarms pages cover the add-ons.
Ana's ruling: a pump with no backup is a pump with a lot of faith. She's a librarian. She keeps a second copy of everything.
Some listings in this table describe themselves as more than sump pumps. A listing may name sewage and effluent use, with septic tanks among its uses, or sewage and wastewater drainage, alongside the basement. The pick notes flag those.
That's the maker's description, and we report it as written. If you want a pump sold just for clear groundwater in a sump pit, pick one whose listing names only that job. If you need a sewage ejector pump for a basement bathroom, that's a different job with its own rules, and a plumber should size it.
Not every house needs a sump pump.
The NDSU page adds one more thing to know before buying. It says almost all sump pumps come with a tool list and directions, and replacing one shouldn't be difficult for the average person. The wiring is another matter. Leave any hard-wired or new-outlet work to a licensed electrician.
We started with every live sump pump listing in our data on 2026-10-31. We kept primary pumps only, which leaves out standalone battery backups, alarms, switches and pump parts. A pump stayed in if its maker or listing states the flow in GPH and the switch type. Then we sorted by stated flow, highest first. We kept the first two from each brand and the first four at each horsepower size.
Every value in the table and the notes comes from the maker or the Amazon listing, shown as stated. Flow is compared only as the maker lists it. We don't turn gallons per minute into gallons per hour, and we don't guess a missing max head. Price plays no part in the order, and the page shows none.
The list can change from week to week as listings come and go. The rule stays the same. If a pump leaves, the next one by stated flow takes its spot.
Read the plate first. Then read the chart at your own lift.
There isn't one best sump pump for every house. NDSU Extension says no size is correct for all homes: the drainage area, the depth to groundwater and the depth of the basement decide it, and a 1/3 HP pump suits most houses. Pick by your pit's size, how fast it fills and how high the pipe climbs, then compare flow at that lift.
Neither is better everywhere. NDSU Extension says a 1/2 HP pump moves more water and lifts it higher than a 1/3 HP pump in similar conditions. Where water flows into the pit slowly, the bigger pump gives no advantage. Where the flow can turn rapid, the 1/2 HP pump may keep up where the 1/3 HP pump may not.
Cast iron is the housing material the listing states, and most listings here state it. This list doesn't rank by material, because no source we read compares how housings hold up. Choose the size, switch and lift first. Then read the maker's manual for its notes on care and service life.
This page doesn't rank brands. The list keeps at most two pumps from any one brand, so several brands share the spots, and the order follows stated flow only. Each brand's page shows its full lineup on Amazon US with the same fields, and a dash where the maker doesn't state a value.
This page doesn't summarize buyer reviews yet, and it gives no star ratings. Picks follow the stated rule: the maker's listed flow and switch type, the horsepower and the brand caps. When we've read buyer reviews on a product's own Amazon page, we'll add a short general note, with no quotes or numbers.
None of the listings here gives a noise level in decibels, so we can't rank them by sound. Community Association Underwriters of America says submersible pumps are much quieter than pedestal pumps, whose motors stand above the pit. Every pump in this list with a stated style, apart from one primary and backup combo, is listed as submersible.
