- Description: Five submersible pumps compared on the numbers that actually matter when you have to carry one down a ladder: published weight, footprint, flow at 5 ft and vertical lift.
- Author: Eli Johnson
- Tags: Tools & Home Improvement, Home Improvement, #Water Pumps

The best lightweight submersible sump pump here is the AQUASTRONG ESU100PM, at a published 8.51 lb with an 11 x 6.3 x 9.85 in body and a claimed 4,500 GPH at 5 ft of lift. If the water you're clearing sits shallow on a pool cover rather than deep in a pit, the 2 lb AgiiMan 850GPH pump is the better buy.

Weight is the specification that splits this field, and it splits it hard. One pump in this group is listed at 2 lb, another at 12 lb, and the horsepower ratings barely track that spread. A 1/2 HP cast iron pump weighs more than a 1 HP thermoplastic one. So a shopper filtering on horsepower ends up carrying the heaviest unit down the ladder, which is exactly backwards.

## How I screened these five pumps

I started from the utility and sump pump listings and worked only from what each seller publishes. No claim below comes from anywhere else.

Three data points survived the screen, because all five listings carry them in a comparable form:

1. **Published weight or footprint.** Four of the five state a weight. Every one states dimensions, so a pump with no weight figure can still be placed by its body size.
2. **Flow at a stated lift.** Four listings quote gallons per hour at 5 ft. That "at 5 ft" is the part shoppers skip.
3. **Maximum vertical lift.** Three quote it: 30 ft, 31 ft and 31 ft.

What got cut from the write-up rather than the shortlist: anything I could not check. None of these listings publishes a decibel figure, so I say nothing about noise. Only one publishes a warranty term, so warranty appears in exactly one product section. Two of the five state the discharge port size in NPT; for the others I describe the adapter claim instead of inventing a thread size.

The order below runs winner first, then by how well each pick fits a specific job. Horsepower is not the ranking axis. If it were, the heaviest pump in this set would sit near the top on a technicality, and that helps nobody who has to lift it.

## Does a lightweight submersible sump pump exist, really?

Partly. That word matters, so here it is straight: no manufacturer in this group markets a product as a lightweight submersible sump pump. There's no industry weight class, no threshold, no certification. What you get instead is a published weight figure on most listings, and you compare them yourself.

The spread here is real. The lightest pick is 2 lb. The heaviest is 12 lb. That's a six-fold difference across five products in the same category, and it maps almost entirely onto material rather than power.

- **Thermoplastic housings** are what the AQUASTRONG, FOTING and Limodot pumps use, per their listings. AQUASTRONG describes reinforced engineering thermoplastic that resists corrosion and abrasion.
- **ABS shell** is what AgiiMan states for its pool cover pump, and it's the lightest here by a wide margin at 2 lb.
- **Cast iron and stainless steel** is the WAYNE CDU800, at 12 lb, and it's the only pump in the group with a published warranty.

So treat "lightweight" as your own filter, not a promise on the box. Decide the weight you're willing to carry, then read the listed figure. That's the honest version of this search.

## Which weight figure should you actually trust?

The listed weight is the pump alone in most cases. It does not include hose, water, or the extension cord you'll drag along. That changes the maths.

Here's the trick with submersible pumps: the number that determines whether you can handle one is not weight in isolation, it's weight plus how awkward the body is to grip while wet. The AgiiMan is 4 x 16 x 4 in, a tall narrow column at 2 lb. The AQUASTRONG is 11 x 6.3 x 9.85 in and 8.51 lb, a squat block with a shorter reach. Both are manageable one-handed. The 12 lb WAYNE at 12 x 9 x 9 in is a two-handed lift out of a wet pit.

FOTING is the awkward case. Its listing publishes 13 x 8.7 x 6.2 in but no weight. I won't guess at it. What I can say is that its footprint is the longest of the three thermoplastic pumps, and FOTING's own listing mentions a rounded handle designed to prevent cuts, which reads as a pump meant to be picked up rather than left in a pit.

One more thing most shoppers miss. A 25 ft cord, as Limodot lists, adds bulk you carry every time. A 10 ft cord, as FOTING lists, is lighter to coil but forces you to add an extension. Neither is free.

## 1\. AQUASTRONG 1 HP Sump Pump 4500 GPH Submersible Water Pump — Best overall

**At 8.51 lb with a claimed 4,500 GPH at 5 ft, this is the best balance of carry weight and real drainage power in the set.**

[![AQUASTRONG turquoise submersible pump with bottom suction base — the 8.51 lb body is the lightest of the three full-power picks](https://m.media-amazon.com/images/I/41ERa2jQnuL._SL500_.jpg)](https://www.amazon.com/dp/B0C9QCCBVW?tag=usebeacons-20)

**Best for:** carrying a pump between a pit, a window well and a flooded crawlspace **Skip it if:** you need a permanent pit pump that switches on by itself

What separates this pump inside this group is the ratio. It's the lightest of the three high-flow pumps at 8.51 lb, and it's the second-cheapest of the five. AQUASTRONG states 4,500 GPH at 5 ft, which works out to the 75 gallons per minute in its own copy, with lift claimed up to 30 ft of vertical height. That's within a whisker of the FOTING figures, from a smaller 11 x 6.3 x 9.85 in body.

The listing describes a bottom suction design that filters debris and takes water down to 1/5 inch from the surface. Bottom suction is a genuine trade-off rather than a straight win: it gets you lower, and it puts the intake where sediment sits. If you're clearing a silty crawlspace, expect to rinse the base.

Operation is manual by design. AQUASTRONG's own phrasing is plug in to play, unplug to stop, so there's no float switch and no unattended running. It also sells faster than anything else here, which is worth knowing when you're weighing an unfamiliar brand against a familiar one.

**Pros:**

- Lightest of the three high-flow picks at 8.51 lb
- Smallest footprint among the 1 HP pumps
- Claimed 4,500 GPH at 5 ft and 30 ft lift
- Second-cheapest of the five
- Sells faster than the rest of this set

**Cons:**

- No float switch, so it runs only while you're watching
- Bottom intake sits where sediment collects
- No published warranty term
- Only two sellers list it

## 2\. AgiiMan 850GPH Pool Cover Pump — Best budget pick

**At 2 lb it's the only pump here you can carry up a ladder in one hand, and the cheapest of the five.**

[![Green AgiiMan pool cover pump beside its flat drainage hose — 2 lb and a 4 x 16 x 4 in column make it the easiest here to handle](https://m.media-amazon.com/images/I/51Uf5rToRkL._SL500_.jpg)](https://www.amazon.com/dp/B089274RH8?tag=usebeacons-20)

**Best for:** clearing shallow water off a pool cover or a flat roof **Skip it if:** you need to move water up a full basement lift

This is the outlier, and it's the reason the weight question in this category is worth asking at all. At 2 lb it weighs about a sixth of the WAYNE. The 4 x 16 x 4 in shape is a narrow upright column, which means it drops into places a squat 1 HP pump won't reach.

The published numbers are modest and honest about it. AgiiMan quotes 850 gallons per hour maximum and lists HMAX at 3.2 m, so roughly a third of the lift the big pumps claim. It states 110V at 60Hz and 75W draw, an IPX8 waterproof rating, and a maximum water temperature of 95°F. The kit includes a 16 ft anti-twist drainage hose suited to a 1/2 in nozzle, and the shell is described as sturdy ABS built to resist bad weather.

Read the category path before you buy: this is sold as a pool cover pump first. For standing water on a cover, a shallow window well, or a flat roof, that's the right tool. For a basement pit with a long vertical run to a discharge point, it isn't, and no amount of patience fixes a 3.2 m lift ceiling.

**Pros:**

- Only 2 lb, the lightest by a factor of four
- Cheapest of the five picks
- 16 ft anti-twist hose included
- IPX8 rating and stated 75W draw

**Cons:**

- 850 GPH is the lowest flow claim in the set
- Lift tops out around 3.2 m, far below the others
- 95°F water temperature ceiling
- Hose suits a 1/2 in nozzle, not standard 1-1/2 in discharge

## 3\. FOTING 1HP Sump Pump 4600GPH Clean/Dirty Submersible Water — Best upgrade

**The highest flow claim among the thermoplastic pumps, and the only one shipping three separate hose adapters.**

[![FOTING blue and black submersible pump with removable base plate — the adapter set covers 3/4 in garden hose through 1-1/2 in discharge](https://m.media-amazon.com/images/I/41LM2TcQOVL._SL500_.jpg)](https://www.amazon.com/dp/B09Y918453?tag=usebeacons-20)

**Best for:** jobs where hose fittings change from one use to the next **Skip it if:** you want a published weight before you buy

FOTING's spec sheet reads like the AQUASTRONG's with a small margin added. It claims 4,600 GPH at 5 ft, 76 GPM, and lift up to 31 ft, against 4,500 GPH and 30 ft. Whether one foot of lift and 100 GPH changes your day is doubtful. What does change it is the fitting kit.

The listing states a 1-1/2 in NPT discharge, a 3/4 in NPT garden hose adapter, and a third adapter that fits 1-1/2 in, 1 in or 1 in NPT hose. That's the widest published compatibility here, and it's the difference between pumping today and driving to a hardware store. FOTING also lists a removable bottom for cleaning, a rounded handle, thermoplastic housing, and built-in automatic thermal overload protection against dry running.

The gap is the weight figure. FOTING publishes dimensions of 13 x 8.7 x 6.2 in but no pound number, so in a guide built on carry weight it can't take the top spot. The 10 ft cord is also the shortest stated here, which usually means an extension cord in the mix. It's the slowest seller of the three thermoplastic pumps too.

**Pros:**

- Highest flow claim in the set at 4,600 GPH
- Three hose adapters plus 1-1/2 in NPT discharge
- Removable bottom for cleaning
- Thermal overload protection against dry running

**Cons:**

- No published weight, the only pick missing that figure
- 10 ft cord is the shortest stated here
- Slowest-selling of the thermoplastic pumps
- No published warranty term

## 4\. Limodot Sump Pump Submersible With 25Ft. Hose — Best minimal setup

**Hose and a 25 ft cord in the box, so a 10.8 lb pump is the only thing you need to carry to the job.**

[![Limodot red and black pump coiled with its 25 ft hose — cord and hose included mean nothing else to source](https://m.media-amazon.com/images/I/41Tog3wVEzL._SL500_.jpg)](https://www.amazon.com/dp/B0DNZF9KXS?tag=usebeacons-20)

**Best for:** someone who wants hose and cord in the box and nothing to source **Skip it if:** you already own hose and a long extension cord

Every other high-flow pick here asks you to supply a hose, a cord, or both. Limodot bundles a 25 ft hose and a 25 ft cable, which is the longest published cord in this group by 15 ft. For a one-off flooded corner, that removes the two trips to the garage that usually eat the first twenty minutes.

The pump itself is listed at 1 1/2 HP with 4,000 GPH at 5 ft, or 66 gallons per minute, and a maximum lift of 31 feet. Note the inversion: it carries the highest horsepower figure and the lowest flow claim of the three big pumps. That's a useful reminder that horsepower on a listing is not flow. Limodot states thermoplastic construction, premium bearings, a hardened stainless steel motor shaft, and automatic thermal overload protection. Suction reaches down to 1/5 inch, with a 1-1/2 in outlet and two adapters for 1 in hose.

At 10.8 lb it's the second-heaviest here, and 13 x 9 x 6 in is a long body. It also shares the top price position with the WAYNE, which is a lot to pay for a pump with no published warranty when the other premium pick publishes three years.

**Pros:**

- 25 ft hose and 25 ft cord included
- Longest published cord in the set
- Stated stainless steel motor shaft and premium bearings
- Suction down to 1/5 inch with two adapters

**Cons:**

- Lowest flow claim of the three high-flow pumps at 4,000 GPH
- 10.8 lb, second-heaviest here
- Premium price position with no published warranty
- Model name on the listing is generic, making replacement parts harder to match

## 5\. WAYNE CDU800 1/2 HP Submersible Sump Pump — Best premium

**The only pick with an automatic float switch and a published 3-year warranty, and the heaviest of the five at 12 lb.**

[![WAYNE CDU800 cast iron pump with vertical float switch attached — the switch is what lets it run unattended in a pit](https://m.media-amazon.com/images/I/31fAGzfcSeL._SL500_.jpg)](https://www.amazon.com/dp/B0002YVPQW?tag=usebeacons-20)

**Best for:** a permanent basement pit that has to run unattended **Skip it if:** you plan to carry the pump up and down stairs regularly

This one wins the specification that matters most for a real sump pit and loses the one this guide is built around. WAYNE lists an integrated vertical float switch tested to 1 million cycles, which is the only automatic operation in this group. Every other pick starts when you plug it in and stops when you pull the cord. A pit that fills while you're at work needs a float.

The rest of the sheet backs it up. Cast iron and corrosion-resistant steel construction, 5,100 GPH, the highest flow claim of the five, from the smallest horsepower rating at 1/2 HP. A 1-1/2 in NPT discharge that WAYNE says meets standard building codes, assembly in the USA, and a 3-year warranty, the only warranty term published by anyone here. The top suction design is claimed to reduce clogging and remove air lock without a weep hole, which is the opposite approach to the bottom-suction pumps and better suited to silty pits.

Then the weight: 12 lb, in a 12 x 9 x 9 in cast iron body. It's the heaviest and the most expensive of the five. Fit it once, leave it in the pit, and that hardly matters. Carry it between three jobs a month and it matters every time.

**Pros:**

- Only pick with an automatic vertical float switch
- Highest flow claim at 5,100 GPH from 1/2 HP
- Published 3-year warranty, the only one here
- Cast iron and stainless steel build
- Top suction resists clogging without a weep hole

**Cons:**

- Heaviest of the five at 12 lb
- Most expensive pick here
- Cast iron body needs two hands out of a wet pit
- No hose or extended cord included

## Flow, lift and the specification most buyers misread

Every flow claim in this set carries a hidden condition, and it's the phrase "at 5 ft". A pump rated 4,500 GPH at 5 ft is not moving 4,500 gallons an hour when you're pushing water 20 ft up and out a window. Flow drops as lift rises. That's how these pumps work, and the listings quote the friendly end of the curve.

So read the pair of numbers together:

- **AQUASTRONG:** 4,500 GPH at 5 ft, max lift 30 ft
- **FOTING:** 4,600 GPH at 5 ft, max lift 31 ft
- **Limodot:** 4,000 GPH at 5 ft, max lift 31 ft
- **AgiiMan:** 850 GPH max, HMAX 3.2 m
- **WAYNE:** 5,100 GPH, 1/2 HP

The second misread is horsepower. Limodot lists 1 1/2 HP and claims 4,000 GPH. WAYNE lists 1/2 HP and claims 5,100 GPH. Three times the horsepower, less flow on paper. Horsepower without a matched flow-at-lift figure tells you very little, and it's the number that pushes shoppers toward heavier pumps for no measured gain.

Measure your actual vertical run from the water surface to the discharge point before you choose. If that run is over 3 m, the AgiiMan is out regardless of how light it is.

## What owning one actually involves

A portable pump is not an install, it's a routine. Here's what the listings tell you about that routine.

Cleaning comes first. AQUASTRONG and Limodot both draw from the bottom, down to 1/5 inch, which means the intake sits in whatever settled out. FOTING lists a removable bottom specifically to make that rinse easier. WAYNE takes the other route with top suction, which its listing credits with less clogging and no need for a weep hole.

Cord and hose management is the second habit. Limodot's 25 ft cord and 25 ft hose go back in a coil after every use. FOTING's 10 ft cord means an extension cord lives with the pump permanently.

Dry running is the third. FOTING and Limodot both state built-in automatic thermal overload protection, which cuts the motor before it cooks if the water drops away. The manual pumps have no float, so you stay with them until the job is finished. That is the real cost of a plug-in-to-start pump, and it's why the WAYNE exists.

## The verdict

The best lightweight submersible sump pump for most buyers is the AQUASTRONG ESU100PM. At 8.51 lb it's the lightest of the three high-flow pumps, the smallest at 11 x 6.3 x 9.85 in, the second-cheapest of the five, and its claimed 4,500 GPH at 5 ft with 30 ft of lift sits within a rounding error of the FOTING that costs more. For a pump you pick up, move, use and put away, that combination is hard to beat here.

Two conditions flip it. First, if the water is shallow and the discharge run is short, take the AgiiMan at 2 lb. Its 850 GPH and roughly 3.2 m lift ceiling won't clear a basement, but nothing else here drops into a 4 in gap or goes up a ladder one-handed. Second, if the pump is going into a pit and staying there, take the WAYNE CDU800\. Its exact advantage is the integrated vertical float switch tested to 1 million cycles, plus a published 3-year warranty and a cast iron body. That's automatic operation nobody else in this group offers, and 12 lb stops mattering the moment the pump stops moving.

FOTING earns its place on fittings: three adapters and a 1-1/2 in NPT discharge, if changing hose sizes is your reality. It just won't publish a weight.

## FAQ

### Is a lightweight submersible sump pump worth it over a cast iron one?

A lightweight submersible sump pump is worth it when you move the pump. The 8.51 lb AQUASTRONG and 2 lb AgiiMan are one-handed carries; the 12 lb cast iron WAYNE is not. But the WAYNE is the only pick with a float switch and a 3-year warranty. Portability and unattended operation are different jobs, so buy for the one you actually have.

### Which is the best lightweight submersible sump pump for a basement pit?

For a basement pit, the best lightweight submersible sump pump is a compromise you should probably skip. A pit that fills unattended needs the WAYNE CDU800's vertical float switch, and that pump weighs 12 lb. If you're pumping out a flooded basement by hand and then putting the pump away, the 8.51 lb AQUASTRONG with 30 ft of claimed lift is the better fit.

### What does the flow rating on these pumps actually mean?

The flow rating on these listings is measured at a stated lift, almost always 5 ft. AQUASTRONG claims 4,500 GPH at 5 ft, FOTING 4,600 GPH, Limodot 4,000 GPH. Push water higher and real output falls. Check the maximum lift figure alongside it: 30 ft, 31 ft and 31 ft respectively, against roughly 3.2 m for the AgiiMan.

### AQUASTRONG or FOTING: which should I pick?

Choose AQUASTRONG for weight, FOTING for fittings. AQUASTRONG publishes 8.51 lb and a compact 11 x 6.3 x 9.85 in body with 4,500 GPH at 5 ft, and costs less. FOTING claims 4,600 GPH and 31 ft lift, and ships a 1-1/2 in NPT discharge plus two extra hose adapters, but publishes no weight and only a 10 ft cord.

### What is the most common mistake buying one of these pumps?

The most common mistake buying one is shopping horsepower instead of flow at your actual lift. Limodot lists 1 1/2 HP and 4,000 GPH; the 1/2 HP WAYNE claims 5,100 GPH. Measure the vertical distance from the water surface to your discharge point first, then match it to the published lift figure. Ignore the horsepower badge entirely.

Measure two things before you order: the vertical run from water to discharge, and the weight you're willing to lift out of a wet pit. Those two numbers pick the pump for you faster than any specification sheet. For most people the answer is the AQUASTRONG ESU100PM, not because it leads on any single figure, but because 8.51 lb and a claimed 4,500 GPH at 5 ft is the only combination here that doesn't ask you to give something up. Light enough to carry, strong enough to matter. Check the current listing and the included adapters before you commit.
