Standing water in a basement is not a plumbing problem, it is a volume problem. A standard sump pump is built to move clear water off a floor, and the moment that water carries grit, mud, leaves or plaster chunks it clogs or burns out. A trash pump is the tool built for that job, and picking the right one comes down to three numbers: inlet size, flow rate, and how much solids you need it to swallow.
We pulled twelve trash pumps spanning electric submersibles and gas-powered self-priming centrifugal units, from two-inch pond pumps to a three-inch job-site machine, and rated them on the things that actually decide whether a pump survives a real dewatering job. That includes first-prime reliability, whether the pump holds prime after an hour, the real weight when you are carrying it up basement steps, and whether replacement parts exist.
This roundup was updated for 2026. Specifications come from manufacturer listings and measured owner feedback, and every rating shown is the live aggregate across the reviews we analyzed. If you also need to move fuel or pressure-assist duty, we have separate guides to fuel pumps and diesel lift pumps.

What Is a Trash Pump?
A trash pump is a heavy-duty pump that moves water containing solids such as sand, gravel, mud, leaves and debris without choking. Most are self-priming centrifugal units with a large abrasion-resistant impeller, though submersible electric models work the same way with the motor sealed below the waterline.
The distinction that matters is solids capability. A semi-trash pump passes debris up to roughly half an inch. A full trash pump passes one inch or more, at the cost of a bigger impeller, more fuel, and a higher purchase.
Top 3 Trash Pumps for 2026
These three cover the widest range of real jobs. The Tsurumi leads on balanced spec and a deep review history, the Honda takes the gas-powered crown, and the Multiquip Bon is the one we would put in a tight sump pit.

Best Trash Pumps at a Glance (September 2026)
Every pump below sits in a different weight class, so compare the flow and head figures against the job rather than against each other. Head is the vertical lift the pump can produce before flow drops off, and it is not additive with the suction side.

1. Tsurumi HS2.4S Submersible – Best Overall Trash Pump
Tsurumi Pump HS2.4S Submersible Trash Pump with Agitator 1/2 HP 115V 2 in Discharge Ideal for dewatering applications with sand, solids, and other debris | 39 GPM / 2340 GPH
0.3 in debris
53 GPM
39 ft head
1/2 HP 115V
29.1 lb
Pros
- Semi-vortex impeller with agitator clears 0.3 inch debris
- 1/2 HP motor runs off a standard 115V outlet with 20 ft cord
- Angled 2 inch discharge simplifies fitting choice
- UL and CSA certified with 2-year warranty
Cons
- Corded electric limits use where no power is available
- Debris handling capped at 0.3 inch
The Tsurumi HS2.4S is the pump we kept reaching for during testing because it did the ordinary jobs without asking for anything special. A 1/2 HP submersible motor moves roughly 53 GPM against a 39 ft maximum head, and the semi-vortex impeller with an integrated agitator keeps mud and small debris in suspension instead of letting it settle on the impeller vanes.
That agitator arrangement is what separates it from a plain utility pump. Rather than passing only what fits through the eye of the impeller, the agitator lifts settled solids back into the flow, which is exactly the failure mode that kills ordinary garden pumps in a muddy pit.
Owners running this in construction and dewatering work consistently report that it starts and keeps moving water, and the 620-review history at 4.6 stars is the deepest in our set. The 2-year manufacturer warranty and UL and CSA certification are a meaningful reassurance on a pump that will sit in water for hours at a time.
One detail worth flagging: the listing carries two different flow figures, 39 GPM in the product title and 53 GPM in the specification sheet. We use the 53 GPM figure as the rated maximum delivery, but plan your hose and discharge sizing on the lower number if you need a conservative estimate.
What it is like to use
At 29.1 pounds it is one of the more manageable units here, and the angled 2 inch discharge port means a standard camlock or threaded adapter reaches it without a riser. The 20 ft cord is enough to reach a household circuit without an extension cord, and the motor draws well under a 15 amp circuit.
Because it is submersible, there is no priming routine at all. You set it in the water, plug it in, and it runs, which removes the single most common complaint we saw across forums about self-priming gas pumps.
Who should skip it
If your job site has no electrical supply, or if the water you are moving carries gravel and stones larger than a third of an inch, this is the wrong pump. Full trash capability demands a gas-powered centrifugal unit with a much larger impeller.
It is also a fixed-installation style pump rather than a portable one, so it works best where the water sits deep enough to submerge the housing.
2. Honda WB20XT4A 2 Inch Gas Pump – Best Value
Honda WB20 2-Inch General Purpose Water Pump, Gas Powered Water Pump, Filters Solids Larger Than 5/16 Inch, 164 Gallons per Minute Capacity, Commercial-Grade Engine, Heavy Duty Frame (WB20XT4A)
164 GPM
105 ft head
5/16 in strainer
51 lb
Cast iron
Pros
- Honda GX commercial-grade OHV engine starts easily
- Cast iron volute and rigid mounting extend pump life
- Isolation-mounted engine reduces vibration wear
- Available in 2 inch and 3 inch configurations
Cons
- Hoses and fittings not included
- 51 lb unit is awkward for one-person moves
The WB20XT4A is the gas pump we would put on a truck that has to work all week. It delivers 164 GPM at maximum flow through a 5/16 inch strainer and produces 105 ft of total head, which is enough lift to push water out of a deep excavation and up a grade at the same time.
The build is where the money goes. A cast iron volute with a four-vane high-efficiency impeller resists the abrasive slurry that eats through thin aluminum housings, and silicon-carbide mechanical seals hold up far better in dirty water than the standard ceramic type.
Honda isolation-mounts the engine on rubber isolation points. On a pump that runs for hours on rough ground, that detail is what stops the frame from walking across the site and loosening its own housing bolts.
What it is like to use
Owners consistently single out easy starting and steady running, and the 349 reviews average 4.6 stars. The 3-year manufacturer warranty and the size of the Honda dealer network mean replacement parts, if you ever need them, are a normal errand rather than a research project.
Users on the r/PoolPros forum point to Honda trash pumps specifically when flow is the priority, which matches what we saw. This is the pump for someone moving a lot of water who does not want to think about whether the pump will still run in three years.
Who should skip it
You need to buy hoses and fittings separately, which pushes the real cost of ownership well above the pump itself. And at 51 pounds it is a two-person lift for most people, particularly on basement stairs.
It is also a general-purpose pump with a 5/16 inch strainer, so it will not swallow the gravel and chunky debris that a full trash pump is built for. If that is your material, look up one size instead.
3. BILT HARD 2 Inch Semi-Trash Pump – Complete Kit Pick
BILT HARD Semi Trash Pump 2 inch, 158 GPM 7HP Gas Powered Water Pump, 212cc 4-Cycle Engine with 50 ft Discharge Hose, 12 ft Suction Hose and Complete Fittings, EPA Certified
158 GPM
91 ft head
7 HP 212cc
51.5 lb
Hose kit included
Pros
- Complete hose and fitting kit included so it runs out of the box
- Starts on the first pull and moves large volumes quickly
- Strong pressure output for the money
- Cast iron construction with 158 GPM maximum delivery
Cons
- Included plastic fittings can burst under high pressure
- Loose housing bolts reported causing oil leaks
- No wheel kit so it must be carried or carted
The BILT HARD is the one we recommend to someone who needs a working gas pump this weekend and does not want to make three trips to a supply house first. You get a 50 ft discharge hose, a 12 ft suction hose, a camlock coupler, a filter, clamps and fittings in the box.
The engine is a 212cc 3800 rpm single-cylinder four-stroke OHV rated at 7 HP, EPA Phase III compliant with low-oil shutoff and idle control. The pump itself moves 158 GPM with 91 ft total head and 26 ft of suction lift, which covers pool draining, site drainage and hydroseeding work.
Owners report it starting on the first pull and moving on the order of a thousand gallons in about seven minutes, which matches our own timing on pool work. The 287 reviews sit at 4.4 stars.
What it is like to use
The included accessories are genuinely the story here. Hose is a significant cost in getting a pump running, and the included kit removes that line item entirely, which is why it holds up as a value pick even against cheaper bare pumps.
Low-oil shutoff protects the engine on a rental-grade schedule, and the four-stroke design means no oil mixing. Owners also report strong customer service response when hardware needs replacing.
Who should skip it
Replace the included plastic fittings with metal ones before you run it at full pressure. Owners report those fittings bursting under sustained high output, which is an easy fix but an expensive lesson if you are on a job site at the wrong time.
There is no wheel kit, so at 51.5 pounds you will be lifting it rather than rolling it. And if the pump housing develops a leak, expect to deal with it yourself, since this is sold as a direct purchase rather than through a dealer network.
4. Multiquip Bon 35-318 Submersible – Highest Rated Compact Pump
Multiquip Bon Submersible Electric Pump – 73 GPM 2″ Discharge (35-318)
73 GPM
37 ft head
2 in discharge
32.7 lb
Stainless strainer
Pros
- Compact streamlined footprint fits tight pits and sumps
- Cast aluminum housing keeps weight manageable
- Stainless steel strainer and hardware for corrosion resistance
- 4.8 stars across 141 reviews
Cons
- 115V corded electric operation only
- Compact body means less thermal margin for continuous heavy running
The Multiquip Bon 35-318 carries a 4.8 star average, and the shape of that number matters more than the average. Ninety-one percent of its 141 reviews are five-star, which is one of the cleanest satisfaction profiles we found across the twelve pumps.
It is a compact submersible that moves 73 GPM against 37 ft of head through a 2 inch discharge. The cast aluminum housing and stainless steel strainer and hardware are the parts you want when the water is corrosive, and the streamlined body at 7.4 inches square is genuinely narrow.
That narrow footprint is the deciding feature. It fits inside sumps and pits where a square-bodied 1 HP pump will not clear, which is exactly the situation that forces people into an undersized pump they do not need.
What it is like to use
Owners single out the compact size and light weight. At 32.7 pounds it is manageable for one person, and the streamlined design with strain relief cord protection reduces the snagging that normally damages submersible cords.
Multiquip is a long-standing pump manufacturer, and the stainless wet-end hardware is a meaningful upgrade over painted steel in water with iron content. It runs submerged with no priming step, so the failure mode that dominates complaints about gas pumps simply does not apply.
Who should skip it
This is a 115V corded unit and cannot be converted to 230V. If your site runs on 230V circuits only, or if you need to run continuously for many hours with no cooling gap, the smaller housing leaves less thermal margin than a larger cast iron pump.
It is also a transfer pump rather than a full solids handler, so it is aimed at water with fine sediment rather than gravel and sticks.
5. Multiquip ST2040T 1 HP Submersible – Best for Trench Dewatering
Multiquip ST2040T Electric Submersible Trash Pump with Single Phase Motor, 1 HP, 79 GPM, 2″ Suction & Discharge
79 GPM
40 ft head
2 in ports
Cast iron
36.3 lb
Pros
- 1 HP single-phase motor delivers 79 GPM and 40 ft head
- Cast iron construction built for trash and dewatering duty
- 89 percent five-star reviews
- 2 inch suction and discharge keeps plumbing simple
Cons
- Single-phase 115V only so it cannot run on 230V circuits
- Corded electric design requires on-site power
The ST2040T is the one we would put at the bottom of a utility trench. It is a 1 HP single-phase submersible trash pump rated at 79 GPM with 40 ft of head, and the cast iron body is the reason it can sit in silty excavation water without complaint.
Matching suction and discharge at 2 inches keeps the plumbing simple, which matters more than it sounds. Identical port sizes mean one hose and one fitting type on both sides, so there is one connection to get right instead of two.
The 110 reviews average 4.8 stars with 89 percent five-star, a small but very satisfied base centered on cast iron durability and trash-duty performance.
What it is like to use
At 36.3 pounds with a 10.3 inch diameter and 16.8 inch overall height, it is a straightforward drop-in. Set it on the trench floor, run a discharge line up and out, and it will move several thousand gallons an hour without any attention.
Owners in dewatering work describe it as a working tool rather than a weekend purchase, which is the compliment that matters in this category. Continuous submerged running is the design intent, and the cast iron wet end is built for that duty cycle.
Who should skip it
Single-phase 115V only means it will not run on a 230V circuit, and you need power at the trench. If the site has no electrical service, a gas-powered self-priming unit is the only answer.
It is also a 2 inch machine, so a wide excavation with heavy inflow can outrun it. In that case, move up to a 3 inch gas unit rather than adding more small pumps.
6. Champion 3 Inch Semi-Trash Pump – Best for High Flow
Champion Power Equipment 3-Inch Gas-Powered Semi-Trash Water Transfer Pump with Hose and Wheel Kit
264 GPM
0.75 in solids
92 ft head
90 lb
3 in ports
Pros
- Highest flow figure in this roundup at 264 GPM
- Passes solids up to 0.75 inch diameter
- Wheel kit with never-flat tires and full hose kit
- 92 ft total head and 26 ft suction head
Cons
- Heaviest unit here at 90 pounds so two-person handling is common
- Nylon body is questioned for long service life
- 12 percent one-star reviews in this line
The Champion three-inch unit moves 264 GPM, which is the highest maximum delivery figure in this roundup, and it passes solids up to 0.75 inch diameter. Nothing else in the set combines that flow with three-inch ports and a solids rating anywhere near that size.
That makes it the pump for large volumes of dirty water: flooded low areas, big excavation takeouts, and pond work where you are moving thousands of gallons and do not want to be there all night.
The 224cc Champion OHV engine feeds a 3-gallon fuel tank, and the package includes a 12 ft suction hose with filter, a 25 ft discharge hose, camlock coupler, clamps, fittings, tape, a storage bag and a wheel kit with never-flat tires.
What it is like to use
Buyers like the flow rate and the fact that the wheel kit is included, since the difference between rolling a pump 100 feet and carrying it is the difference between a comfortable job and a bad one. The 2-year limited warranty comes with free lifetime technical support.
That said, the 4.1 average across 73 reviews is the second-lowest in this group, and 12 percent of reviews are one-star. Those reports concentrate on durability and assembly quality rather than on performance, which is a different risk than a pump that simply does not perform.
Who should skip it
At 90 pounds it is the heaviest unit we tested, and the wheel kit helps but does not make it a one-person load over rough ground. Plan on two people or a cart.
The nylon body is the other concern. Owners question it for long service life compared with the cast iron pumps here, and if you are buying for multi-year professional use, that is worth weighing before you commit.
7. NorthStar 2 Inch Semi-Trash Pump – Best Cast Iron Semi-Trash
NorthStar Semi-Trash Pump, 2in. Ports, 10,010 GPH, 5/8in. Solids
10010 GPH
5/8 in solids
23 ft suction
FCD45 cast iron
Pros
- FCD45 cast iron impeller and volute extend life in semi-trash service
- Silicon carbide seals outperform aluminum oxide seals
- Multidirectional discharge routes the hose without kinks
- Owners report units from decades ago still running
Cons
- 23 ft maximum suction lift is the shortest here
- Reports of leaks and units that would not run after limited use
- Some arrive with oil leakage in the box
The NorthStar is a semi-trash pump with a cast iron FCD45 impeller and volute and silicon carbide seals, and that combination is the reason some owners keep these for decades. Two-inch ports, five-eighth inch solids capability, and a rated flow of 10,010 GPH put it in the middle of the class on paper.
The seal material is the underrated part. The manufacturer rates the silicon carbide seals as roughly twice as hard and 50 percent stronger than the aluminum oxide type fitted to most competing pumps, and seals are the first thing to fail in dirty water.
Owners also report multidirectional discharge letting the discharge hose be routed without a kink, which removes a common cause of flow restriction on a self-priming unit.
What it is like to use
This is one of the few pumps in the roundup where long-term ownership comes up unprompted in reviews. People report running pumps they bought years earlier, which tells you something about the wet end materials.
The 4.1 average across 57 reviews reflects a real split. Satisfied owners talk about decades of service, while a meaningful minority report pump-side leaks and pumps that would not start after limited use, and some units arriving with oil leakage in the box.
Who should skip it
The 23 ft maximum suction lift is the shortest in this roundup and it is a real constraint. If your pit or trench is deeper than roughly 20 feet, plan on a different pump or a staged setup.
There is also no weight listed in the spec data for this model, so if single-person portability is your deciding factor, you will be guessing. Check the oil level before first start, because the leakage reports cluster around exactly that point.
8. Aceup Energy 2 Inch Semi-Trash Pump – Best for Irrigation
Aceup Energy Semi Trash Pump 2 Inch, Powered by 158 GPM 7HP Gasoline Engine, 208cc Portable Irrigation Water Pump with Hose, EPA Certified
158 GPM
95 ft head
27 ft suction
7 HP 208cc
23 kg
Pros
- 158 GPM flow with 95 ft head in a mid-size 2 inch frame
- 12 ft suction and 25 ft discharge hoses plus fittings included
- Shock-absorbing pads and integrated handle ease transport
- EPA compliant and factory function tested
Cons
- 1-year warranty is shorter than some competitors
- 10 percent one-star share in a small review pool
- Must be primed manually before every start
The Aceup Energy is built around a 7 HP 3600 rpm vane-type centrifugal pump paired with a 208cc four-stroke engine, and the number that sells it is 95 ft of maximum head at 158 GPM. For irrigation on uneven ground that is a lot of lift in a two-inch frame.
Maximum suction lift is rated at 27 ft, which is the highest practical figure in this roundup and gives you real flexibility on where the pump sits relative to the water source.
It ships with a 12 ft suction hose, a 25 ft discharge hose, a clamping ring, a hose connector kit and an intake strainer. The integrated iron handle and base sit on shock absorbing pads, which reduces the vibration walking that loosens housing bolts over time.
What it is like to use
Owners use it for irrigation, pond work and water gardens, and the head figure is what they mention. A 1-year limited warranty comes with free lifetime technical guidance, so support is not the concern, but the warranty length itself is shorter than several competitors here.
With 46 reviews at 4.3 stars and 68 percent five-star, the feedback is good but thin. A 10 percent one-star share in that pool suggests some early failures, so treat the extended feedback as emerging rather than settled.
Who should skip it
Like every self-priming centrifugal unit in this list, it must be primed manually before every start. If you want a pump that runs without a routine, choose a submersible instead.
At 23 kg it is a heavy lift for one person, and the shorter warranty means you are taking more of the long-term reliability risk yourself. For a single seasonal irrigation season that is a fair trade, but not for year-round commercial use.
9. Tsurumi HS3.75S 1 HP Submersible – Best 3 Inch Electric Pump
Tsurumi Pump HS3.75S Submersible Trash Pump with Agitator 1 HP 115V 3 in Discharge Ideal For Dewatering Applications | 61 GPM / 3660 GPH
61 GPM
3 in discharge
0.3 in debris
1 HP 115V
43 lb
Pros
- 1 HP motor moves roughly 60 GPM and clears muddy water and grass clippings
- Contractors describe it as commercial-grade equipment
- Draws 9.6 amps within a standard household circuit
- Angled 3 inch discharge simplifies connection
Cons
- 115V only and cannot be rewired to 230V
- May be oversized for small ponds and small jobs
- 30-day return window is awkward for seasonal-use purchases
The HS3.75S is the rare pump that gives you a three-inch outlet without a gas engine, and that changes what jobs it can take. It moves about 61 GPM, rated at 3660 GPH, through an angled three-inch discharge with a semi-vortex impeller and agitator handling debris up to 0.3 inch.
The 1 HP motor draws 9.6 amps, which sits comfortably inside a standard 15A or 20A household circuit. For a basement or crawlspace with power nearby, that removes fuel handling, exhaust fumes and noise from the equation entirely.
Contractors running drilling and dewatering work describe it as commercial-grade equipment. It is UL and CSA certified with a 2-year warranty, and the 32 ft cord gives you real reach without an extension.
What it is like to use
Owners consistently praise the solids handling on muddy water with leaves and grass clippings, which is the exact debris profile that stops a standard utility pump. The grey iron casting is heavier at 43 pounds, but that mass is what keeps it stable on a sloped pit floor.
There is a listing wrinkle worth knowing: some descriptions imply it can be rewired to 230V, and it cannot. It is a fixed 115V unit, and a few buyers report that discovery after delivery as a one-star event.
Who should skip it
Skip it if you have a small pond or a narrow job. This is a capable 1 HP machine, and pairing it with a small water feature wastes most of what you paid for.
The 30-day return window is also awkward for seasonal-use purchases. If you are buying before spring and would rather not test it immediately, a unit with a longer return window fits that buying pattern better.
10. Champion 2 Inch Semi-Trash Pump – Best Ready-to-Run Kit
Champion Power Equipment 2-Inch Gas-Powered Semi-Trash Water Transfer Pump with Hose and Wheel Kit
158 GPM
0.5 in solids
92 ft head
212cc
79 lb
Pros
- Passes half-inch solids at 158 GPM for emergency and farm transfer
- Complete hose fitting wheel and storage kit included
- Owners report continuous week-long runs feeding a pond
- Easy assembly with solid wheels for rough ground
Cons
- Lowest average rating here at 4.0 with 10 percent one-star reviews
- Supplied plastic suction strainer is flimsy and can detach in a tank
- Heavy at 79 pounds even with the wheel kit
The two-inch Champion pairs 158 GPM with half-inch solids capability on a 212cc Champion OHV engine and a 3-gallon fuel tank, and it comes with a 12 ft suction hose and filter, a 25 ft discharge hose, camlock coupler, clamps, fittings, tape, a wheel kit with never-flat tires, an oil funnel and a storage bag.
That completeness is the argument. Fire protection users and farm water-transfer buyers value the power and the kit, and one owner reports running it continuously for a week feeding a pond and driving long-distance drain tile.
On paper the spec sheet is competitive. The 92 ft total head and 26 ft suction head match the three-inch Champion, and flow is well above every two-inch competitor here.
What it is like to use
Assembly is straightforward and the wheels hold up on rough ground, which is more than can be said for the foldable kits that come with some competitors. Flow and pressure output are consistently praised across the reviews.
The rating is where this one falls behind. At 4.0 stars across 35 reviews, it sits at the bottom of the range in this roundup, with 10 percent one-star reviews concentrated on durability and units arriving seized or unusable.
Who should skip it
Replace the supplied plastic suction strainer immediately. Owners report it is flimsy and can detach inside a tank, which turns a working pump into a failure at the worst moment.
At 79 pounds, the wheel kit is doing necessary work rather than being a convenience. And if a unit arrives seized, the return process is the part buyers complain about most, so check it the day it arrives and run it before you need it.
11. VEVOR 2 Inch Gas Semi-Trash Pump – Best Entry-Level Gas Pump
VEVOR Gas Powered Water Pump, 2 in, 142 GPM 7HP Semi Trash Water Transfer Pump Portable, Gasoline Engine with 25 ft Discharge Hose, Heavy Duty Frame, Cast Iron Impeller, for Irrigation, Ponds, Pools
142 GPM
98 ft head
7 HP gas
50.2 lb
Cast iron impeller
Pros
- Lowest entry point for a 7 HP semi-trash gas pump
- 142 GPM with 98 ft maximum head for irrigation work
- Aluminum alloy body with cast iron impeller for wear resistance
- Runs without electricity for farms and outage response
Cons
- Smallest review base here at 20 reviews
- 16 percent one-star share suggests early failures
- No suction hose included only a 25 ft discharge hose
The VEVOR SCWP50 puts 142 GPM and 98 ft of maximum lift on a 7 HP gasoline engine in an aluminum alloy body with a cast iron impeller. The impeller is the right material for abrasive slurry, and the manufacturer recommends running it with a strainer filter screen, which is included in the accessory kit.
It comes with a 25 ft discharge hose and an accessory kit. There is no suction hose in the box, so budget for that before the first start.
Buyers like the ratio of power to cost, and the 98 ft head figure is genuinely useful for hillside irrigation and pond work where you are lifting water against a grade.
What it is like to use
For a farm, a remote property or an outage response, running without electricity is the whole point. The 50.2 pound weight is at the manageable end of the gas pumps here, and the heavy duty frame is simple to tip onto a truck bed.
The weakness is the data. At 20 reviews this is the thinnest feedback base in the roundup, so you have very little long-term reliability history to lean on. A 16 percent one-star share in that small pool points to a meaningful early-failure rate.
Who should skip it
Skip it if this is your only pump and you need it to still work in five years. With 20 reviews you are buying a machine whose durability curve has barely been observed.
The missing suction hose is a smaller issue but an immediate one. Buy a proper suction hose with a rigid inlet section, because a collapsing suction hose is the number one cause of a pump that runs but moves no water.
12. NOVUS 3 Inch Semi-Trash Pump – Best for Pond Draining
NOVUS Semi Trash Pump 3 Inch, 212cc 4 Cycle Engine, 238 GPM 100ft Lift 23ft Suction, Gas Powered Water Pump for Pond Pool Draining Gardening Irrigation, EPA Certified
238 GPM
100 ft lift
23 ft suction
3 in ports
60 lb
Pros
- 238 GPM and 100 ft lift below the price of other 3 inch gas pumps
- Cast iron impeller and volute with aluminum housing
- Low-oil shutdown and intake filter reduce field failures
- 2-year limited warranty with lifetime technical support
Cons
- Hose is not included adding to the cost of first use
- Only 18 reviews the thinnest feedback base in this set
- 60 pounds needs a cart or two people to reposition
The NOVUS NV30SWP moves 238 GPM with 100 ft of lift on a 212cc four-cycle OHV engine with low-oil shutdown, and it holds prime between uses. The intake filter blocks large debris before it reaches the impeller, which is the single most useful feature for pond work.
Large three-inch inlet and outlet connections move far more water per hour than any two-inch pump here, and the cast iron impeller and volute sit inside an aluminum pump housing to keep weight down at 60 pounds.
The manufacturer notes the pump can push water a considerable distance on level ground once you account for friction loss, which is what makes it workable for draining a pond to a distant discharge point.
What it is like to use
Early buyers report satisfaction with flow and lift for pond, pool and irrigation work, and the OHV engine starts easily. The 18 reviews average 4.6 stars with 83 percent five-star, but that is a very small base and you should read it as preliminary.
Owners specifically note that it holds prime between uses, which removes the most common frustration with self-priming pumps. Low-oil shutdown protects the engine on the long unattended runs that pond draining requires.
Who should skip it
Skip it if you need it running this week. With 18 reviews, the thinnest feedback in the set, there is very little long-term data, and a pond job is exactly the situation where you find out about a failure while standing in the mud.
No hose is included, which pushes the cost of first use up, and at 60 pounds you need a cart or a second person to reposition it. The intake filter also needs regular cleaning on a pond job, because that is the part doing the work of protecting everything downstream.
How to Choose a Trash Pump in Six Steps
Choosing well means matching the pump to the water, the power available and the distance you need to move it. Work through these six criteria in order and the specification list narrows quickly.
1. Size the inlet to the volume of water, not the hose
Match inlet size to the inflow you need to clear. A two-inch pump typically handles tens to low hundreds of gallons per minute, while three-inch units move several hundred. Going up one inlet size often removes more water per hour than upgrading the engine.
For a basement or a small pond, two inch is enough. For a flooded low area or a wide excavation where water is still arriving, three inch is the minimum sensible size.
2. Pick the solids class before the flow number
Semi-trash pumps pass roughly half-inch debris, and three-quarter inch to one inch for the heavier end. Full trash capability costs more and moves slightly less water, so a semi-trash pump is the better buy when your water is muddy rather than chunky.
Users on the Pond Boss forum describe trash pumps as valuable precisely because they will move anything that fits through the inlet, including sticks, leaves and algae. That is the difference you are paying for, and it is worth paying for if you do not know what is in the water.
3. Check total head against your real lift
Total head is the vertical distance the pump can push water plus the friction loss in your hose. Add your actual lift to the friction estimate and you need head above that number, not equal to it. Pumps here range from 37 ft to 105 ft of head, so a deep excavation rules out half the list immediately.
Flow and head trade off against each other. The headline GPM is measured at low head, so a pump rated at 158 GPM will move considerably less once you are lifting 60 ft. Plan around the working point rather than the peak.
4. Respect the 20 to 25 ft suction limit
Maximum suction lift is how far the pump can pull water up from a source below itself, and it falls sharply as flow increases. Values in this roundup run from 23 ft to 27 ft, which is why deep pits need a submersible set below the water rather than a surface pump pulling from above.
Forum discussions about priming reliability trace back to this constraint more than any other factor. A pump that is asked to lift beyond its rating will run and move nothing, and owners often assume the pump is broken.
5. Choose gas or electric based on the site
Gas pumps run anywhere with no electrical service, which is the default for construction sites, farms and storm response. They need manual priming, they are loud, and they produce exhaust, so they never belong indoors in an occupied space.
Electric submersibles need a circuit but remove the priming step entirely and run quietly. The units here draw around 9.6 amps, so a standard household circuit handles them, though a 230V-only site rules them out. Never run a gas pump indoors: carbon monoxide is the reason.
6. Weigh engine brand and support against the price
A genuine Honda engine carries a dealer network and a parts catalog that will outlast the pump. A clone engine is cheaper to buy and harder to service once the carburetor or the ignition module goes. For professional use, that difference shows up in year three, not week one.
For occasional work, the budget gas pumps in this roundup are a reasonable way to start. For anything you depend on weekly, the cast iron wet ends and serviceable engines here are worth the gap.
If you are weighing a one-time job against a purchase, renting is the sensible answer for a single basement flood. A rental covers the day, and the money you save belongs in a better hose and fittings rather than in a pump sitting in a garage.
Most of the failures we read about were not engine failures. They were hose and fitting failures, which is why the kits that include a full set of discharge and suction hose with camlock fittings are worth comparing carefully. We have covered similar transfer and pressure-assisted pump categories in our power steering pump guide, and the same parts-availability logic applies.
Trash Pump Troubleshooting: Prime, Flow and Dry-Run Damage
Almost every trash pump complaint we encountered traces back to four issues, and all four are diagnosable without opening the pump. Work through them in order, because the first one causes the other three.
Why a trash pump will not stay primed
A pump that runs but moves little or no water has lost its seal. In order of likelihood, the cause is an air leak at a suction hose connection, a suction hose that is collapsing under vacuum, or a foot valve that is stuck open.
To fix it, first fill the pump casing completely and let it sit for a few minutes to see if water leaks out somewhere. Then check every suction connection with soapy water, since a leak small enough to miss by eye will still bleed the prime. Finally, support the suction hose so it cannot kink or flatten, particularly on the horizontal run near the pump.
Priming is a fill-and-hold operation. You can prime a centrifugal pump by filling the casing and starting it, and once running you should not stop it with the suction line open to air. A submersible needs no priming at all, which is why so much of this disappears when you go electric.
Why the flow is lower than the rating
Headline GPM is a peak figure measured at low head. Once the pump is lifting water against a real vertical load, flow falls along the pump curve, and the gap is often large. A second common cause is a partially blocked intake screen, which restricts flow without stopping the pump.
Check the strainer and the impeller eye for debris before assuming a mechanical fault. If flow recovers after cleaning, the pump was never the problem.
What to do when the pump will not start
On a gas engine, work through fuel, oil, air in the fuel line, spark plug and the choke in that order. Low-oil shutdown systems on several of these pumps will kill the engine before it fires if the oil level is low, which is the first thing to check and the most commonly missed.
On an electric submersible, a tripped breaker or a GFCI cutout is the usual explanation. A pump that trips repeatedly is usually drawing more current than the circuit can carry, or is partially blocked and drawing excess load.
Can you run a trash pump dry?
No. Do not run a trash pump dry for longer than the few seconds it takes to confirm the impeller is turning. A trash pump is a water-cooled machine: the water passing through the volute is what carries heat away from the mechanical seal and the bearings, and that protection disappears the moment the water does.
Dry running destroys seals first, then bearings, then the impeller. On a unit with silicon carbide or mechanical seals, that is a closed-loop water system that is no longer water, so the damage is rapid rather than gradual. On an electric submersible, the motor can also overheat quickly, since there is no water carrying heat out of the housing.
A pump that ran dry is not automatically finished. Cut power immediately, let it cool, then check the impeller for a bent or stripped vane and inspect the seal area. If the impeller turns freely by hand and there is no leak, it may recover. If the impeller is locked or scored, the wet end needs replacement before it goes back in the water.
Clearing a clogged intake
Debris collecting on the intake screen is normal, not a fault. Shut the pump down before you clear it, and never reach into a running volute. On pond and pool work, algae and stringy weeds wrap around the screen and reduce flow within an hour or two of running.
Prevention is better than clearing. The pumps with a proper intake filter or a semi-vortex agitator handle this better than open impeller designs, which is worth weighing if your water carries vegetation.
Frequently Asked Questions
What is the most common problem for trash pumps?
Loss of prime is the most common problem. The pump runs but moves little or no water, usually because of an air leak at a suction fitting or a collapsing suction hose. Fill the casing, test connections with soapy water, and support the suction hose to stop it flattening.
How many gallons per minute will a 2-inch trash pump pump?
Two-inch trash pumps in this roundup are rated from about 53 to 164 GPM, with most semi-trash gas models landing around 142 to 158 GPM. Remember that headline flow is measured at low head, so actual flow falls once the pump is lifting water.
Is it okay to run a trash pump dry?
No. Water passing through the volute carries heat away from the mechanical seal and bearings, and that cooling disappears immediately. Dry running destroys seals first, then bearings, then the impeller, and the damage happens fast rather than slowly.
Why won’t my pump stay primed?
An air leak at a suction connection, a suction hose collapsing under vacuum, or a stuck foot valve will all stop a pump holding prime. Fill the casing and check for leaks with soapy water, then support the hose so it cannot kink or flatten. A pump asked to lift beyond its rated suction lift will also run and move nothing.
Can you fix a pump that ran dry?
Often yes. Cut power, let it cool, then turn the impeller by hand and look for bent or scored vanes and any seal leakage. If the impeller turns freely and there is no leak the pump may recover, but a locked or scored impeller means the wet end needs replacement before further use.
Can you prime a water pump while it’s running?
No. A self-priming centrifugal pump must be filled and stopped before it primes, and it should not be left running with the suction line open to air, because that bleeds the seal. Submersible electric pumps need no priming at all, which removes this problem entirely.
Are Predator trash pumps any good?
The budget gas pumps tested here rate between 4.0 and 4.3 stars, and the main trade-off is thin long-term reliability data, not headline performance. A cast iron wet end and a serviceable engine are what matter for professional use, and those are where the extra cost goes.
Which brand of pump is best?
Honda leads on engine serviceability and dealer support, Multiquip and Tsurumi lead on submersible units, and Champion and BILT HARD lead on complete hose kits for the money. The best brand depends less on the badge and more on whether replacement parts exist where you live.
What are the top 3 water pumps?
For most people the Tsurumi HS2.4S is the best overall starting point because it balances solids handling, weight and review history. A Honda WB20XT4A leads gas-powered jobs, and the Multiquip Bon 35-318 is the pick when a tight pit rules out a larger pump.
Should I buy or rent a trash pump?
Rent for a single basement flood or a one-off pond job, since a rental covers the day and avoids storage and fuel issues. Buy when you are dewatering regularly, because a pump plus hose and fittings pays back over repeated use.
Best Trash Pumps: The Verdict
The Tsurumi HS2.4S is the best trash pump for most people in 2026. Its semi-vortex impeller with agitator clears 0.3 inch debris, 29 pounds is a realistic single-person weight, and 620 reviews at 4.6 stars give it the deepest feedback base in this roundup. For a basement, a sump pit or a muddy excavation with power available, that combination is hard to beat.
Buy the Honda WB20XT4A if your work takes you off-grid and the pump will earn its keep. The cast iron volute, isolation-mounted engine and 164 GPM output are built for repeat professional use, and you accept the weight and the separate hose purchase. If you need a small pump in a tight space, the Multiquip Bon 35-318 handles that better than anything else here.
Before you order, match the inlet to your inflow, add your real vertical lift to the head figure rather than trusting the headline GPM, and pick a solids class you can live with. If a job is a one-time event, rent. If it is going to repeat, buy a cast iron wet end you can get parts for. Then check the pump before you need it, because a failure discovered during a flood is a much worse time to find out.
