What is the Best Generator for Sump Pump in 2021?

Quick Answer:

Comparison Table for the Best Generator for Sump Pump in 2021

If you are having a difficult time remembering the stats of each generator I’ve listed, this part is for you.

 

Here, we will compare the traits of my top 10 picks. With this comprehensive table, it should be easy for you to choose the best sump pump generator.

Generator View on Amazon Starting Watts (W) Running Watts (W) Runtime at 100% Capacity (Hours) Weight (Pounds) Tank Capacity (Gallons)
DuroStar DS4000S 4000W 3300W 4 h 94 lbs. 3.96 Gal.
WEN DF475T 4750W (Gas) / 4350W (Propane) 3800W (Gas) / 3500W (Propane) 5.5 h (Gas) / 3.5 h (Propane) 105.80 lbs. 4 Gal.
DuroMax XP12000EH 12000W 9500W 7.5 h 234 lbs. 8.3 Gal.
Westinghouse WGen7500 9500W 7500W 4 h 192 lbs. 6.6 Gal.
Champion 3500W 4375W 3500W 6 h 118.80 lbs. 4.7 Gal.
Generac iQ3500 3500W 3000W 4 h 109.10 lbs. 5 Gal.
JEGS 86065 5000W 4250W 4.5 h 130 lbs. 4 Gal.
Firman H05751 7125W 5700W 13 h 196 lbs. 8 Gal.
Briggs & Stratton P300 3000W 2600W 2.5 h 85 lbs. 1.5 Gal.
Dirty Hand Tools 104612 3200W 2800W 3 h 89 lbs. 1.85 Gal.

 

 

As a note, the runtime I’m showing assumes that the generator is running at 100% capacity.

Think of this as a worst-case scenario for the runtime, as the metric I show simulates the generator giving everything it’s got at 100%.

Your sump pump likely has a running wattage of 800 – 2,000W, and most generators on this list have a running wattage of more than or equal to 3,000W.

With this in mind, you can assume that the runtime is significantly longer than listed on the chart.

To find the exact runtime of a given generator while powering your sump pump, find the running wattage of your sump pump, and divide it by the running wattage of the generator.

This number is the percentage of capacity the generator is using, so divide the 100% runtime by this number, and you’ll get a somewhat accurate estimation of expected runtime.

Best Generator for Sump Pump in 2021

1. DuroStar DS4000S | Best Sump Pump Generator on a Budget

best generator for sump pump DuroStar DS4000S

Starting off our list, we have an Amazon’s Choice, the DuroStar DS4000S.

 

This great generator has a lot of great features, and it comes at a great price. You won’t find another generator this well-made at such a low price.

 

Its 4,000 starting watts and 3,300 running watts can easily power your sump pump for many hours.

 

The first great feature of this generator is its two startup methods.

 

The primary method is a very convenient electric start switch. This great feature allows you to start the engine at the flip of a switch.

 

Next, there’s the manual recoil handle. A bit less convenient, this startup method is similar to starting a lawnmower.

 

What’s great about this feature is that it gives you a backup starting method if one fails.

 

In an emergency, this will surely come in handy. If the electric start fails, you can rely on the recoil handle. If the handle breaks, use the electric start.

 

Next, there’s the built-in voltage meter. This feature allows you to monitor the voltage level to ensure your sump pump or any other devices stay safe from overload.

 

If, however, you can’t manage to monitor the voltage closely, this generator is equipped with a surge arrestor. This useful perk automatically prevents overloads.

 

The super quiet muffler is another plus. This feature enables the engine to run at a quiet 69 decibels.

 

Another great feature you get with this generator is its all copper windings. This allows the generator to produce greater power output more efficiently.

 

Next, there’s the low-oil shutdown feature. It is essential because it dramatically lengthens the lifespan of the engine.

 

Note that running the engine when the fuel tank runs low is the leading cause of engine wear and failure.

 

The low-oil shutdown will automatically turn the engine off when the fuel level gets low enough. So, you won’t need to worry about engine damage with this great feature.

 

The built-in wheels and carry handle make this relatively lightweight generateor easy to transport.

 

This generator has a power cluster equipped with two AC 120V outlets and one 120V twist-lock outlet.

 

It’s a pretty limited power cluster, however, it’ll get the job done when it comes to powering your sump pump.

 

With its many great features and incredibly low price, this generator is a safe pick.

 

If you need a generator for your sump pump, and you need to make your budget stretch, the DuroStar DS4000S is your best generator for sump pump.

Expert Opinion: 

2. WEN DF475T | Most Reliable Sump Pump Generator

best sump pump generator WEN DF475T

When it comes to reliability, no generator can beat Amazon’s Choice, the WEN DF475T.

 

With some amazing features and high-quality components, this generator is sure to please.

 

First, it has dual fuel technology.

It allows the generator to be fueled by either gasoline or liquid propane. This feature will no doubt come in handy in the future.

 

With 4750W (gas) / 4350W (propane) starting watts, and 3800W (gas) / 3500W (propane) running watts, this Amazon’s Choice is perfectly capable of powering a sump pump.

 

In emergencies, gas prices tend to skyrocket when the supply runs low enough. Thus, propane can be an advantageous backup power source to obtain in an emergency.

 

Propane tends to be cheaper than gasoline and it’s available in several locations other than gas stations.

 

The next feature provided by this generator is its easy electric start. With the turn of a key, you can easily start this generator.

 

This feature doubles as a security measure. Only you, the keyholder, can start the engine.

 

The WEN DF475T also has a voltage selector built-in.

 

This nifty feature allows you to adjust the voltage from 120V to 240V with the flip of a switch. This is perfect for transfer switches or changing devices.

 

With its quiet muffler, the WEN DF475T operates at a quiet 69 decibels.

 

It has a decent power cluster as well, with two 120V AC outlets, one 12V DC outlet, and one 120V twist-lock outlet.

 

All of these great features come together to form the best sump pump generator for reliability. If you need a generator you can trust, the WEN DF475T is a great pick.

3. DuroMax XP12000EH | Best Sump Pump Generator for Heavy-Duty Use

best generator for sump pump DuroMax XP12000EH

If you need a generator that can do some heavy-duty work, I highly recommend the DuroMax XP12000EH, which is Amazon’s Best Seller.

 

This titan of a generator is guaranteed to get the job done.

 

As the most powerful generator on this list, the DuroMax XP12000EH boasts an incredible 12,000 starting and 9,500 running watts, so running your sump pump will be a breeze.

 

On top of that, this generator comes standard with DuroMax MX2 technology, allowing you to receive maximum power from all of the outlets.

 

With all copper windings, this generator’s engine maximizes fuel efficiency.

 

Additionally, it has a very large fuel tank. At 8.3-gallons, you can fuel up and kick back while this generator powers your sump pump.

 

It is also incredibly durable. With a high-quality steel frame, its engine is well protected from external wear and tear.

 

With its voltage meter, you can monitor the voltage emitted from the engine. Keep an eye on this feature so your electronics don’t get destroyed by a power surge.

 

Next, the DuroMax XP12000EH is equipped with a low-oil indicator. This comes in the form of a bulb that lights up red when oil levels run low.

 

Be vigilant of this light, as running the engine on low oil will wear the internals of the engine down quickly.

 

Finally, this Amazon’s Best Seller has idle control. This regulator automatically controls output levels. It’s an incredibly useful feature that reduces noise and increases fuel efficiency.

 

This is an especially useful feature for sump pumps because you can just hook the generator up to your pump, and let it run.

 

The generator can regulate its output and power efficiently for a significant time period.

 

Overall, this generator is amazing. Not only does it have great power output, but it comes equipped with many amazing features that increase the utility and efficiency of this device.

Expert Opinion: 

4. Westinghouse WGen7500 | Most Convenient Sump Pump Generator

best sump pump generator Westinghouse WGen7500r

With many great features, it’s no wonder why this is the most convenient generator to own on this list.

You won’t need to do much to keep this generator powering your sump pump or anything you want for years to come.

What’s amazing about this product right off the bat is its three distinct startup methods. It can be started by a wireless key fob, or an effortless push-to-start button, or a backup recoil handle.

The key fob is truly unique. Only a few generators can boast having such a unique and convenient feature. You can start your generator from up to 109 yards away.

Next, there’s a very convenient push-to-start button. This well-designed feature is unlike anything I’ve yet seen.

When pushed, a green light will turn on until the engine is turned off. Very easy to use, very well-designed.

Finally, there’s a backup manual recoil start. While it’s the least convenient starting option available to you, it’s still great to have. Like starting a lawnmower, you need to rev the engine on.

This is a good addition to have just in case the two electric start methods somehow fail in an emergency.

Realize that with this generator you have not one, not two, but three unique ways to start the engine.

This will no doubt be an incredible help at some point during an emergency.

If you lose the key fob, break the recoil handle, or somehow the button breaks, you always have another option to fall back on.

Not many generators can do this, not to mention the other great features you get.

First among them are the smart transfer switch. This is ideal for whole house powering, as the generator can automatically detect when to switch from 120V to 240V.

If you want to power your whole home instead of only your sump pump, this generator has you covered.

Next, there’s the voltage/hour meter. This feature allows you to keep an eye on either the voltage of the generator or the current runtime.

This important feature allows you to ensure the voltage is proper for the device you’re charging and predicting runtime.

If, however, you fail to keep a close eye on the runtime, don’t worry, this generator is also equipped with an amazing low-oil shutdown feature.

This nice feature eliminates the risk of internal engine wear by shutting the engine down when fuel levels reach a low enough point.

This is another example of how this is the best sump pump generator for convenience.

You can start it in three different ways, and after filling up the fuel tank, you can just sit back and let it get the job done. And when it runs out of fuel, it will automatically shut itself down.

The maintenance of the engine is further simplified by its air-cooling feature. This efficient method prevents engine overheating by pumping cool air from the environment into the engine.

This is far more efficient than fans because the use of fans requires more power from the generator.

Lastly, the built-in wheels and carry handle allow you to easily transport this amazing generator from point A to point B.

Just another feature that increases the convenience of using this generator.

With all of these amazing convenience features, with three unique starting methods among them, this generator is by far the easiest to use on this list.

If you’re looking for convenience, the Westinghouse WGen7500 is your best generator for sump pump, and more of course.

 

 

Important Features

  • Convenient key fob start
  • Easy push-button electric start
  • Backup recoil start
  • Transfer switch ready
  • Four GFCI 120V AC outlets

When the weather gets rough, you probably need your sump pump more than ever, which is why it’s important for your generator to be able to brave the elements.

The Champion 3500W is well equipped to do just that.

First, it is equipped with three key weather protection features that enable it to survive rain, cold, and external damages.

The cold start feature enables you to easily start the engine when temperatures drop near freezing.

This technology has been proven by Champion Power Equipment to both start and reliably run consistently in sub-zero temperatures.

Next, there’s the plastic flaps that cover the power outlets.

When it’s raining, the last thing you need is water entering your generator’s power outlets. With the Champion 3500W, the hard-plastic flaps will keep the water out of your generator.

Lastly, there’s the durable steel frame which ensures that debris kicked up by storms or any external source of damage is minimized.

Keeping the engine safe from physical damage is a huge plus for inclement weather.

This generator has two great starting options.

One is a key fob that can activate the engine from as far as 80 feet away.

This super convenient feature allows you to regulate your sump pump’s power supply from anywhere in the house.

Next, there’s a convenient electric start switch. Just flip the switch and you’re ready to go. No revving is required with this generator.

Next, there’s the IntelliGUAGE, a meter that triples as a voltage meter, hour meter, and frequency gauge.

The hour meter helps you monitor how long the engine has been running so that you can predict your timing for refueling.

The frequency gauge allows you to monitor the functionality of the motor pump by displaying the frequency in hertz.

And lastly, the voltage meter enables you to keep an eye on the output voltage that the generator is employing. A very useful feature that helps you protect your electronics from overload.

If, however, you aren’t paying attention to the voltage meter, there’s a built-in surge arrestor.

This great feature automatically monitors and protects your sump pump or other electronics from power surges that would otherwise destroy them.

With two 120V AC outlets, one 120V twist lock outlet, and one 30A outlet, you can power a lot more electronics than your sump pump.

You could power your appliances, start your car, or even supply power to your RV.

With many amazing features stacked on top of its incredible weather-proof design, there’s no doubt that when the weather gets bad, the Champion 3500W is the best generator for sump pump.

The secondary starting method is a reliable recoil handle. This classic way of starting the engine is much less convenient, but it’s a reliable backup starting method in case the electric start fails.

 

With two AC 120V outlets and two 120V twist-lock outlets, you can power a few more electronics alongside your sump pump.

 

If you’re looking for a generator that can survive some wear and tear, the JEGS 86065 is your best generator for sump pump.

8. Firman H05751 | Best Sump Pump Generator for Runtime

best generator for sump pump Firman H05751

If you need your generator to run for a long time, the Firman H05751 is your best bet. With an amazing runtime on top of some other great features, this generator is sure to please.

What makes this generator stand out is its amazing runtime.

With a whopping 13 hours of continuous output of 5700W, this generator can easily power your sump pump through the nastiest of storms.

With dual fuel technology, you can use either gasoline or propane as a fuel source. This feature will certainly be useful in an emergency because gasoline might become harder to access than propane.

Propane tends to be cheaper than gasoline too, which is an added benefit.

Another great feature is the low-oil shutdown.

Many generators on the list have this feature, so it’s a great touch for this generator. You won’t need to worry about your engine getting damaged with this feature.

With its specially designed whisper series muffler, this generator operates at a reasonably quiet 74 decibels. Not the quietest generator on the list, but this feature is a nice touch.

With the spark arrestor, dangerous sparks will never be produced by this generator. This great feature dramatically increases the safety of this generator by completely curtailing its fire risk.

Another feature of this generator is its convenient electric start switch and manual recoil backup.

These two starting methods add a layer of utility to this generator. If one starting method fails, you have another one to rely on.

With two 120V AC outlets, one 120V twist lock outlet, and one 30A outlet, this generator is capable of powering several devices at the same time, such as your sump pump.

I find this to be one of the best generators for sump pumps. With an incredible runtime and several other great features, the Firman H05751 is a great pick.

 

 

Important Features

  • An amazing 13 hours of runtime
  • Dual fuel technology
  • Low-oil shutoff
  • Quiet operation
  • Spark arrestor
  • Electric start with recoil backup
  • Two 120V AC outlets
  • One 120V twist lock outlet
  • One 30A outlet
  • Wheel kit and folding handle

Pros

Cons


User Experience:

Let’s see what Amazon users have to say about this sump pump generator.

 

1) We’ve used it for quiets some time.

The assembly was very minimal and it’s working very well.

 

2) It’s a little expensive and very loud.

But it’s dual fuel.

 

3) One propane tank and this bad boy runs for 1 full day.

It has a really high output power.

 

4) You have to be careful since it doesn’t have a lo THD.

That means you can’t use it with electronics.

 

5) I don’t like the panel display for the propane tank.

It’s not accurate.

 

6) I haven’t tested thoroughly yet.

But it seems to be running OK so far.

10. Dirty Hand Tools 104612 | Best Sump Pump Generator for Mobility

best generator for sump pump Dirty Hand Tools 104612

If for any reason you need to take your generator on the go, this is the generator for you.

 

With mobility being the focus of the generator, you can easily take this generator where it needs to go.

 

The first feature is the unique 4-wheel frame.

 

This makes transporting this generator around your home very easy. Perhaps you need to move it from storage to your sump pump, perhaps there you need to leave the house with it.

 

No matter the reason you need to move, it is highly portable and easy to store.

 

This generator is built with an efficient inverter engine. Its very efficient design increases the output and reduces fuel consumption by making the engine more dynamic when running.

 

The special economy switch regulates fuel consumption further, more finely tuning the engine to the situation at hand. With this feature, fuel efficiency increases as noise production and emissions decrease.

 

Another great feature is the two starting methods.

 

The first one is a key-operated electric start. Just turn the key and you’re good to go. This also adds a layer of security as only the keyholder can operate the generator.

 

The secondary starting method is a standard manual recoil handle. Not the most elegant of starting methods, but it gets the job done and it’s reliable.

 

This generator also has a pretty versatile power cluster. With two 120V AC outlets, one 120V twist-lock outlet, one USB port, and one 12V DC outlet, this generator can power many devices.

Best Generator for Sump Pump — Buyers Guide

By now, I’ve covered a ton of information about the best possible generators for sump pump in 2021.

Now, it’s time to turn to you, and answer some of your most frequently asked questions I found on Google.

I believe combining the information you find in the reviews, comparison table and the FAQ section, you can easily pick your suitable sump pump generator.

Let’s take a look then.

What’s the best generator for sump pump in 2021 if I’m on a budget?

If you need to save some money in this buying process, there are a few options for you. First, I recommend the DuroStar DS4000S.

This is a cheap generator at only about $340, but it’s still a very high-quality device. It has an impressive wattage and runtime for the price at 3,500W running for a minimum of 4 hours. It’s a great pick for a great price.

The other low-price generator I would recommend is the JEGS 86065.

For only about $360, you can get a durable generator that’s pretty average in other respects. Its tough steel tubular design, concealed wiring and covered outlets make this generator pretty tough.

Generally, the cheaper the generator is, the less special features it has. Both of these generators are pretty average; however, I would give the DuroStar DS4000S the edge.

It’s less expensive, and in my opinion, has more stand-out features than the JEGS 86065.

If you choose to look elsewhere for generators, don’t get reeled in by too low of prices. If it looks too good to be true, it probably is. Buy generators from trusted sources and don’t get scammed.

Price isn’t an issue. What’s the best generator for sump pump in terms of power?

When it comes to power, no generator on my list of 10 beats the DuroMax XP12000EH.

This generator produces an astounding 12,000 starting watts and 9,500 running watts. This is a well-above average power output, and it should be perfect for sump pumps.

On top of its amazing output, it is stacked with great features like dual fuel technology, all copper windings, low-oil indicator, spark arrestor, and idle control.

This generator is top notch and worth every penny, so I highly recommend it if you have the money to buy it.

So, if you need a good deal while searching for the best generator for sump pump, check this one out.

What’s the best sump pump generator that lasts for a long time?

If you need a long-lasting generator, again I recommend the DuroMax XP12000EH.

This generator just has too many great features included. It’s guaranteed to keep your sump pump running during storms and floods for years to come.

The longevity measures it has are more numerous than any other on the list. Spark arrestor, idle controls, all copper windings, and circuit breakers work together to make this generator last for a very long time.

Another option for a long-lasting generator is the Firman H05751.

It’s also a dual fuel generator, however it’s equipped with a low-oil shutoff feature that automatically turns the engine off when low fuel levels are detected.

It’s an especially good pick because of its unique Phoenix flat head block. This feature keeps the generator running cool and efficient.

So, if you need a generator that’s in it for the long haul, I recommend these two great generators.

How do I know if I’m overpaying for a generator?

Generator prices are fairly predictable if you know what you’re looking for.

Typically, you can take the running wattage of a given generator and divide it by ten.

I call this the 1/10th rule, because the price of a generator is usually somewhere in the ballpark of 1/10th of the running watts.

The price usually deviates from this rule when there are special features added. Depending on the significance and number of the special features, you can expect generator prices to rise.

Let’s take the DuroStar DS4000S as an example. With a running wattage of 3,300, and a price of about $340, this generator adheres pretty closely to the 1/10th rule.

An example of a pretty significant deviation of the 1/10th rule is the Westinghouse WGen7500.

The price is much higher than 1/10th of its running wattage, as it’s about $849 to 750W, respectively. The likely culprits of this price increase are its many special features.

Features such as its remote start key fob, low-oil shutdown, digital hour meter, and GFCI outlets most likely went into consideration when pricing the generator.

Keep this point of advice in mind when shopping for generators. Only special features should make a generator deviate from the 1/10th rule.

If a generator seems to be only average with no special features, and it costs significantly more than 1/10th of its running watts, it’s most likely overpriced.

Keep an eye out for these things down the road, and you shouldn’t ever overpay for a generator.

How do I know which generator is right for my sump pump?

To answer this, you need to ask yourself why you need a generator and a few more questions.

Obviously, you need a backup power supply for your sump pump.

First, you should do some research on your sump pump.

Most importantly, find the starting and running watts requirement for the pump.

From my research, this figure typically lies between a minimum of 800W to a maximum of 2500W.


Each generator on this list is capable of accommodating a sump pump, but in different capacities
.

Each of these generators support typical sump pumps for different amounts of time that I refer to as runtime.

Your questions could be the followings:

a) Is runtime the most important factor for you?

The generator with the best runtime is the Firman H05751.

With an impressive 13 hours of runtime, you can expect your sump pump to work for a long time in the event of a power outage.

b) Is convenience key for you?

If you want the most convenient generator to power your sump pump with, the Westinghouse WGen7500 is an ideal pick.

This generator has three starting methods, one of them being a wireless key fob that works from up to 109 yards away.

Hypothetically, you could be anywhere inside or near your house when the storm begins. Flooding occurs, then the power goes out. Without even going to the basement, you could activate your generator and power your sump pump at the push of a button.

Why do I need a generator for my sump pump?

The main reason you’ll need a generator other than recreational use is for emergency use. In emergencies, generators are your best friend when the power goes out.

Sump pumps come in handy during storms and flash floods. They keep our basements dry and allow us to prevent thousands of dollars’ worth of damage every year.

But, however, the very storms that make sump pumps useful can render them useless if your power goes out.

This is precisely why you need a reliable generator for your sump pump.

Having this backup plan is essential to be a responsible homeowner.
