For most jobs the Superior Pump 91250 is enough: 1/4 HP, 1800 gallons per hour, and it takes water down to 1/8 inch of the floor. On a flat surface with no pit, the WAYNE WaterBUG gets closer still, to 1/16 inch. Need volume rather than a dry floor, the 1/3 HP Superior 91330 moves 2400 gallons per hour.

A utility pump is not a sump pump. It has no float, no pit and no permanent home — you carry it to standing water, drop it in, run a garden hose out of a window, and take the pump away afterwards. The specification that decides which one you want is not horsepower. It is how shallow it will pump before it loses prime.

This is the size that fits the most jobs. Superior lists 1800 gallons per hour at zero lift and 1200 at ten feet, which is the figure that matters when the hose has to climb out of a basement window. Maximum head is 25 feet.
The detail that makes it useful is the bottom suction design with a serviceable intake screen, which Superior lists as removing water down to 1/8 inch of the surface and passing solids up to 1/8 inch. On a flooded floor that is the difference between finishing with a pump and finishing with towels. The discharge is 1-1/4 inch NPT with a 3/4 inch garden hose adapter included, so a standard hose works.
- Removes water to 1/8 inch of the surface, per Superior Pump.
- Takes a plain garden hose or a 1-1/4 inch line, adapter included.
- Fiberglass reinforced thermoplastic body with a non-clogging vortex impeller.
- Manual switch — there is no float, so it will run dry if you leave it.
- Superior lists a liquid temperature range of 35 to 120°F, so it is not a hot-water tool.
- 1/8 inch solids handling means debris-laden water still needs a screen kept clear.
Verdict: Buy this if you want one pump for hot tubs, window wells, flooded floors and draining a water heater.

Best for a Flat Floor
WAYNE WaterBUG Submersible Water Removal Pump
1350 GPH · 30 ft maximum head · removes water down to 1/16 in of the surface · Multi-Flo top and side discharge · multi-ring suction strainer · garden hose connection · assembled in the USA · per WAYNE’s product page

The WaterBUG trades flow for the last quarter inch. WAYNE lists 1350 gallons per hour and 30 feet of maximum head, and states that it removes water down to 1/16 inch of the surface. If the water is on a floor rather than in a pit, that number is the whole point.
The other design choice is the discharge. WAYNE calls it Multi-Flo: a top discharge for confined spaces such as a window well, a laundry tub or a five gallon bucket, and a side discharge for open areas such as a flat roof, a flooded basement or a shower stall. Switching between them is what lets one pump handle both a narrow pit and a wide floor, and the multi-ring suction strainer keeps debris off the intake.
- Removes water down to 1/16 inch, per WAYNE — the shallowest here.
- Top or side discharge, chosen for the space you are in.
- 30 ft maximum head, the highest lift of the three.
- 1350 GPH is the lowest flow of the three, so large volumes take longer.
- Still a manual pump — it does not switch itself off.
- The strainer needs cleaning if the water carries silt.
Verdict: Buy this if the water is spread across a floor and you want it virtually dry without a wet vacuum.

Superior Pump 91330 Submersible Utility Pump
1/3 HP · 2400 GPH at 0 ft, 1680 GPH at 10 ft · 25 ft maximum head · removes water down to 1/2 in of the surface · passes 1/8 in solids · 1-1/4 in NPT discharge with 3/4 in garden hose adapter · 4.1 A · per Superior Pump’s product page

Same body, bigger motor. Superior lists 2400 gallons per hour at zero lift and 1680 at ten feet, against 1800 and 1200 for the 1/4 HP version. On a hot tub, a pond or a flooded crawl space with real depth, that is a third off the time.
Read the trade-off before you assume bigger is better. Superior lists this one as removing water down to 1/2 inch of the surface, where the 1/4 HP model reaches 1/8 inch. More power, less shallow. If the job ends with a wet floor rather than a drained pit, the smaller pump is the better tool — which is not what the horsepower number suggests.
- 2400 GPH at zero lift and 1680 GPH at ten feet, per Superior Pump.
- Same discharge and adapter as the 91250, so hoses interchange.
- Solid copper windings and dual o-ring motor seals, per Superior Pump.
- Stops at 1/2 inch of water, four times deeper than the 91250.
- Draws 4.1 A, so watch what else is on the circuit.
- Manual switch again — no float, no automatic shutoff.
Verdict: Buy this when the volume is large and something else will handle the last half inch.
Utility Pump or Sump Pump?
A sump pump lives in a pit, has a float switch, and runs without you. A utility pump is portable, switched by its plug, and has no float at all. Using a utility pump as a sump pump means it either runs dry or does not run when you need it. If the water keeps coming back to the same pit, you want the right sump pump and a check valve, not a portable. The same goes for a crawl space where water pools after every rain: see our crawl space sump pump picks.
Read the Shallow-Water Number, Not the Horsepower
Manufacturers publish two figures that decide this purchase. Flow tells you how fast a volume moves; the shallow-water rating tells you how much is left when it stops. Superior lists 1/8 inch for the 91250 and 1/2 inch for the more powerful 91330; WAYNE lists 1/16 inch for the WaterBUG. Buy on the second number unless you are emptying something deep.
Lift Is Not Free
Every foot the hose climbs costs flow. Superior’s own figures show the 91250 dropping from 1800 gallons per hour at zero lift to 1200 at ten feet, and the 91330 from 2400 to 1680. Measure the real height from the water to where the hose discharges — basement window, driveway, yard — and read the rating at that height rather than the headline.
What These Pumps Are Good For
Draining a hot tub or a pool cover, emptying a water heater faster than gravity will, clearing a window well, pumping out a flooded crawl space, moving water from a pond or a boat, and drying a floor after a burst supply line. For the last one, find the cause before you buy the pump: our guide to finding a water leak covers it.
How We Pick Pumps
Nobody pays to appear here. Picks come from field experience on real jobs — which tools hold up in actual homes and which ones cause callbacks — together with published manufacturer specifications read off the maker’s own product pages rather than guessed.
We weigh value rather than price, because a pump that fails on the one day you need it is not a deal, and we name a small number of genuine winners instead of listing everything on the market. Full method: how we pick.
Why Trust Plumbing Picks
These picks come from a Journeyman Plumber — State of Georgia Licence #JP507711, verifiable through the Georgia Secretary of State’s license verification portal. Nobody pays to be featured and there are no sponsored placements. Some links here are Amazon affiliate links, so we may earn a commission at no extra cost to you, and that does not change which pump gets named. More on who writes this: about Plumbing Picks.
FAQ
What is a submersible utility pump used for?
Moving water that is not going to move itself: draining a hot tub, pool cover or water heater, emptying a window well or a flooded crawl space, and clearing standing water off a floor. It is portable and manually switched, so it is a tool you carry to the water rather than an installed appliance.
How low will a utility pump drain?
It depends on the model, and this is the spec to compare. Superior lists the 91250 at 1/8 inch of the surface and the 91330 at 1/2 inch; WAYNE lists the WaterBUG at 1/16 inch. Anything left below that figure comes up with a wet vacuum or a mop.
Can I use a utility pump as a sump pump?
No. A sump pump has a float switch and runs unattended in a pit; these are manually switched and will run dry if you forget them. For a pit that fills on its own you need a proper sump pump, and ideally a battery backup for outages.
Does a utility pump connect to a garden hose?
Yes, on all three here. The Superior pumps have a 1-1/4 inch NPT discharge with a 3/4 inch garden hose adapter included, and the WaterBUG connects to a standard garden hose. A wider hose moves more water, so use the 1-1/4 inch discharge if you have the line.
Can it pump dirty water?
Lightly. Superior lists both pumps as passing solids up to 1/8 inch, and WAYNE fits the WaterBUG with a multi-ring suction strainer. None of these is a trash pump or a sewage pump, so keep them out of water carrying gravel, leaves or waste.
Bottom Line
Buy the Superior Pump 91250 as the default: enough flow for most jobs and down to 1/8 inch. Buy the WAYNE WaterBUG when the water is on a floor and you want it virtually dry, or when the hose has a long climb. Buy the Superior 91330 when the volume is large and the last half inch does not matter. None of them replaces a sump pump, and none of them is built for waste — a bathroom or laundry that drains below the sewer line needs a solids-handling sewage ejector pump sitting in its own sealed basin.
