Quietest Sump Pumps 2024: Reviews and Buying Guide


If you’ve been to places with unpleasant weather conditions like I have, you KNOW what challenges come with the weather.

There can be extreme heat, relentless raining on most days (Cue: London), and most importantly: Sudden flooding of the house due to poor drainage systems.

Believe me, a soaked and flooded basement is just the start of your problems. If the water isn’t moved, it can damage the flooring of your house.

Leave it for too long and the furniture will get damaged as well. Poor drainage, damage to your water discharge, and water blockade can turn your house into an island (pun intended).

The easiest way to eradicate the problem is to dig a sump pit in the basement and install a pump that discharges the water away from your house at a safe distance.

At A Glance: Our Top Picks for Quietest Sump Pumps

These pumps are known as “Sump Pumps.” These pumps are handy as none of us want to spend the weekend mopping up a pool of water.

I’ll be discussing the topic in this article. I’ll be helping you guys with a list of some of the quietest sump pumps around.

After all, no one likes too much noise to disturb the harmony of their houses while removing a water poodle down at the basement.

While I’m at it, I’ll be throwing in a buying guide in the article as well. This is to help you find your own machine if you’re not satisfied with my choices. But I bet you will be.


When searching for an ideal sump pump for your basement, it’s easy to get lost amidst numerous products.

That’s why I came up with the following list. The short reviews of mine will give you options that you can depend on when it comes to buying.

Some of these products can be used in draining water from your gardens, pools, and lawns as well. Let’s get to it!

Quietest Sump Pumps 2021

When looking for sump pumps, I prioritize sturdiness.

As it turns out, WAYNE CDU980E is a sturdy pump with a compact design.

You have stainless steel covering a cast iron construction at the bottom. This is ingenious on the part of the makers.

Cast iron bottom gives it stability. Stainless steel protects it from rust.

Don’t think that the “Cast Iron Design” is going to add extra weight to the machine. The impeller is lightweight. Polypropylene float is light as well.

I found the switch extremely silent. It’ll work to reduce the water level but you won’t hear the pump while it’s doing its bidding. Oh, it’s automatic.

Sump pumps are generally installed in the basement. These things prevent flooding of the house by moving water. We know this much for sure.

WAYNE CDU980E is even better at this job. While doing what it’s meant for this pump protects itself from abrasion as well. It has an abrasion-resistant glass.

Why do I call it best submersible sump pump out there? That’s because this tool disperses and filters debris as well. That too at a constant rate.

As a result, you won’t have to clean and maintain it constantly. Yes, it “Almost” doesn’t clog at all.

Just to let you know, the suction design is top-notch. The makers eradicated any chance of air getting in and blocking the pathways.

The discharge of WAYNE CDU980E accounts for 1-1/2” NPT. Yes, it’s large. Plus, it has a thick motor.

These two things work in perfect unison to balance out a large float as well. It’s a vertical float type. It won’t obstruct the machine. Plus, users won’t have to worry about damages at all!

The motor is clearly not for show. It’s powerful enough to discharge 4600 gallons of water per hour. I expect nothing less from a ¾ horsepower motor. The entire unit is sealed.

Don’t worry about water getting in and disrupting the circuits. They are compartmentalized for safety.

Users don’t need to worry about the power cord as it’s waterproof as well.

Any plumber would be able to install this machine. He/she would need only 15 minutes for the job. It’s assembled in the USA.

I’d advise you to use it with 11 inches or larger sump basins. Forget about weep holes. You won’t need any with Wayne CDU980E.

If you’re a fan of a big and submersible pump for draining water, this is your “Go to” device.

Yes, it might be green in color but who buys these machines to adore them? 

We need a functional product that will keep our basement from flooding. Trust me, Zoeller M53 will do just that!

Installing it is like a breeze. Anyone can do that. Just remember to put the machine in a hole that’s 2 inches wider than the M53 Mighty Mate machine.

Don’t be fooled by the bulky design. Zoeller comes with a mighty motor.

The motor has a horsepower rating of 1/3. It can run with 1550 RPM (Rotations Per Minute). This much is enough to clear out all the water from our basement and keep our homes dry.

The pump flushes water out at tremendous speed. You can discharge water by 45 gallons per minute.

Depending on where you install the pump, the performance may vary. For example, my friend could measure 2680 Gallons of water going out per minute when the pump is installed onto the surface.

Go 5 feet deep beneath the ground and the water flushed out will be the same.

At 10 feet of depth, you’ll be able to flush out 2040 GPH. Go 15 feet deep and it decreases to 1140 GPH.

The entire pump (including the switch box, all the essentials, and the motor) is housed in a Cast Iron frame.

Many would think that weight will be an issue. Surprisingly, the pump weighs 21lbs only. I must say, it’s lightweight when it comes to submersible sump pumps.

The bottom part is made of “Thermoplastic.” As we dig down in our basement, things tend to get hotter underground.

A thermoplastic base prevents heat conduction. Also, plastic is resistant to water and iron-related damages such as corrosion.

As you expect from a reputed brand, the switch is vertical and automatic. It triggers in every two or three minutes depending on the water level. The machine runs for 20 seconds at a stretch.

The motor is strong enough to clear out all the water by then. People can expect this machine to run for 2 – 4 years without a hitch.

The makers gave us users quite a leash with a 9 feet power cord. Don’t worry, it’s powder coated and covered with a waterproof cover.

As with these kinds of sump pumps, the float rises automatically as well. Instead of plastic, this tool has a rubber float. People might argue that the float will solidify with time when penetrating the pump cap.

To prevent that, the makers installed silicon grease. A small piece to be exact.

No, it’s not petroleum grease. People can easily switch it for a new one when it goes bad.

The discharge or exit pipe measures up to 1-1/2" NPT. Rest assured, water can be discharged quickly with an exit pipe this wide. You’ll have two little holes in place through the exit pipe and impeller check valve.

Yes, it can get clogged once in a while. To make sure that air doesn’t block the pipe, a nail is in place.

I loved the fact that the impeller check valve works to perfection. It prevents dust and damp mud from entering the unit.

Once in a while, you’ll have to run some maintenance to clean it. For that, remove the screws from the bottom of the pump and take the check valve out. Clean it and put it back.

Want the quietest sump pump within the capacities of your wallets?

Superior 91250 is just the thing to go for. It’s within the capacities of your wallet.

Don’t fall for the price just yet. One can use this pump to take out water from swimming pools as well as basements. It’s versatility at its very best.

I liked the construction of this sump pump as well. Durable thermoplastic making gives it the edge when working. Thermoplastic prevents damages from overheating.

It’s also beneficial when countering rust and corrosion to give the machine a long life that it deserves.

This little pump is portable as well. It has a carrying handle that assists people in moving it from place to place. It’s lightweight. You won’t feel strained from moving this pump.

I get the fact that this thing has a 6-inch small opening but it fits nicely due to the design. Superior 91250 comes with the facility of water intake from the side and the bottom. This only enhances its performance.

Yes, it pumps water continuously and has a clog-resistant suction mechanism as well.

Superior 91250 doesn’t lack in motor power by any means. The motor dishes out ¼ HP. This is enough to lift water vertically up to 25 feet. The motor features split capacitors to provide you good winding power.

In my opinion, this little machine can handle itself and the water when the going gets tough.

I assure you, all that power won’t go to waste as it pumps out 30 gallons of water per minute. People will have a ¼-inch garden hose attachment as well.

It allows you to move 1800 gallons of water per hour. 1-1/4-inch discharge pipe made of iron won’t let your basement get flooded anytime soon.

The pump is not too big on maintenance. Why?

Because there’s a suction screen that filters out large debris. One can remove and clean it from time to time. This is all the maintenance you’ll need.

As far as the removable materials go, the switch can also be removed.

Yes, this little thing can function without a switch as well. It’s not automatic. You’ll need to shut it off when you’re done. This is perhaps the only drawback I found.

On the bright side, it can be used as a tankless water heater as well!

Since the switch is removable, you can use any float switch replacement you want. Well, as long as the intended switch has a piggyback-style connection. Even non-tethered switches will do just fine.

Superior Pump 91250 comes with a waterproof power cord. It’s replaceable as well. This 10-feet power cord provides people with enough leash to set up this machine without worrying about any kind of tugging or pulling for that matter.

The cord won’t snap or tear up if that’s you’re worried about.

This thing is safe. It’s UL and CUL listed. To make matters easier, It’s CSA certified as well. Even with all the safety precautions, this thing won’t leave you high and dry.

There’s a nifty user manual that tells you what to do to set this thing up and how to operate it to avoid danger.

Since we’re talking about electric sump pumps, it’s the ideal time to mention Wayne VIP50.

It’s lightweight, portable, and extremely easy to operate. This little product comes with a garden hose adapter as well. 

This is to facilitate small-time jobs around the house other than removing water from the basement. Yes, it’s a versatile machine as well.

One look at Wayne VIP50 impressed me. The thermoplastic casing for the unit prevents it from overheating. At this point, we know that Thermoplastic is resistant to corrosion.

Not only that, the machine is sealed. That means you don’t have to worry about air or any other debris getting in.

This is an electric and manual sump pump as well. You can turn on the switch yourselves. When the pump is done, turn it off again. Wayne VIP50 can take out water with up to 3/8-inch solid objects in it.

Otherwise, there’s a float switch that’s adjustable and grants automatic power to it when needed.

Credit goes to the motor for such kind of performance. It comes with 1/2 HP motor. It’s capable enough of removing 2500 Gallons of water per hour.

This is a huge thing considering suburban areas in our country are prone to water logging and floods.

Just to give you an idea, it can pump out 1550 Gallons of water from 10-feet discharge lift. If you go down to 5 feet discharge lift, it can pump out 2000 Gallons per hour.

At 15 feet, it decreases to 900 Gallons per hour. You can’t set it up below this distance.

Makers at Wayne gave this sump pump a 1-1/4-inch discharge outlet. Water drains through this exit pipe rather quickly.

I gave a hint earlier that the pump can be used for other household chores as well. Makers included an extension elbow that adapts to the exit pipe.

Through this, you can pump out water from your boat, lawn, garden and anywhere else.

Yes, it does function as a utility pump as well. One thing you have to remember is that the pump requires AT LEAST 2-5/8 inches of water to prime up and a begin its magic.

One thing I can guarantee my readers is the fact that this is a sump pump for numerous years.

I’ve seen sump pump reviews mentioning that WAYNE VIP50 has the legs to go through as many as 15 years without giving in to physical damages, rust or corrosion.

Wayne WSS30V is the last one on my list of quietest sump pumps.

Don’t confuse it with the older version. It’s upgraded with a cast iron base and Steel body.

Sure, it contributes to the weight of the item yet it makes it more durable than before. The design facilitates no airlocks.

Assembly of this unit is not a problem. In fact, the WSS30V comes fully assembled. Users just have to place it in an appropriate location, set up all the connections, and turn it on.

Speaking of appropriate location, you’ll need 15-inch basin to set this sump pump. The entire setup job requires only 15 minutes of your time. This is a jiffy for a trained plumber.

The main pump has a float switch that’s convenient. As the water level rises, it turns on. The switch is good for 1 million cycles. The motor can pump out 5100 gallons of water per hour when it’s set up at 0 feet from the ground.

Once you set the machine up, it can easily go on for at least five years.

Speaking of performance, this little machine can pump out 4380 Gallons of water per hour when working from a depth of 5 feet. At 10 feet it lessens to 3480 Gallons per hour.

When we go down to 15 feet it further decreases to 2400 gallons per hour. Good news is, it can work from a depth of 20 feet, unlike the other pumps. It pumps out 900 gallons of water from that depth.

This added kit can be used with a backup system. When it is used, it can add further 2900 gallons of water extraction per hour to your primary pump.

Why am I advising people to use a backup? Well, it’s battery powered. Even if electricity runs out while on the job, this unit can take care of things.

The battery runs on a 12V DC connection. This thing is good for removing 10, 000 gallons of water in a single charge.

That’s days’ worth operation uninterrupted. Combine the battery with the AC connection and you have a gem in your hands.

But there’s a hitch. You won’t get the battery with this unit. Luckily for us, it works with any deep cell battery that’s available for purchase.

But when will you know that the item needs recharging?

As it turns out, Wayne WSS30V comes with a monitoring system.

Actually, the machine has red, yellow, and green lights. Each one signifies different states of the battery. Remember to recharge it when the red LED light flashes.

One thing I can guarantee the users is the fact that ½ HP motor is very quiet. I’d say it’s ultra-quiet when at work.

You won’t even notice the muffled sound when working upstairs while this tool is going about its business. And by ultra-quiet, I mean the sound ranges around 45 – 50 dB.

What to consider when buying Sump Pumps?

When you’re out on your own, choosing the sump pumps can be a difficult task.

People must know what they’re looking for and which features they want in their tool.

This buying guide should help you in that regard. In it, I’ve discussed a few factors that will help you in pointing your fingers at the right product.

Consider Overall Making of the Pump

The first thing I’d advise you guys is to consider how the product is built. I’m very particular about the housing of the product.

Good housing determines the durability and sturdiness of the unit. The ideal material will safeguard your machine from rust and decay.

Sturdy material saves it from accidental damages as well.

You’ll find sump pumps made of thermoplastic. This is hardened and heat-resistant plastic that makes the tool lightweight. It then becomes easy to carry and set up.

Thermoplastic pumps won’t rust or decay anytime soon. They are cheap as well.

Stainless steel is an option as well. This thing will carry more weight than thermoplastic. Yes, steel is prone to rust. But the process is slow.

If you want a nice balance between weight and longevity, go for Cast Iron housing. It’s lighter than stainless steel but carries more weight than Thermoplastic.

Beware, it can rust. But there’s a way around it. Simply apply an epoxy coating on it and it’ll safeguard your machine for years.

It has fewer chances of breaking due to continuous usage.

Pick a pump made of any one of these materials. Remember, whichever material you pick will have a direct impact on the price of the machine.

Choose the Right Type of Pump

One thing people will notice right away is the fact that there are many kinds of sump pumps out there.

You’ll have submersible pumps that can work while being beneath the water.

These are the easiest to operate. These things collect water and force it down the drainage systems.

There are pedestal sump pumps as well. These things are portable and don’t require that much maintenance. The important parts are at the top of these machines. One can carry them from one place to another with ease.

On my list, you’ll find the majority of the pumps are portable as well.

You’ll notice a pump with a backup system as well. These are called the backup sump pumps. These things come handy when there’s no electricity.

In the face of a severe flood, these systems come with battery support. Even if the electricity is out, you can run them for hours and discharge water.

You have the water powered pumps as well. These function like a straw. They draw out water from the top of the pump. These things get clogged very often and require frequent maintenance in my opinion.

Each of these types has benefits and drawbacks. It’s just the question of which one you pick and why.

Weigh your cost and benefits. Choose any of the above types that will suit you and run with it.

Pick a Pump with the Ideal Switch

Did you notice I said “Ideal switch?”

That’s because not all kinds of switches will have the same impact on your pump’s longevity.

You’ve got three types of switches with these machines. One is the tethered switch. Pumps with these switches tend to last longer than most.

But there’s a hitch. Tethered switch pumps require people to dig wider sump pits.

Then you have vertical switch pumps. These can fit in narrow sump pits quite easily. But the lifespan of the switch and pumps are shorter than their tethered counterparts.

The third kind is the electric switches. These switches don’t have moving parts, unlike their two cousins.

They won’t get stuck while doing the job. But there ARE downsides. Electric switches are known to be affected by additional materials in the water.

To avoid that, clean the electric probes from time to time.

Get a Measure of the Motor

What I mean to say is, “Check the Horsepower rating.”

When it comes to motors and horsepower, the more the better. Remember: You need the power to gather the water and flush it down the drainage system. More horsepower means the pump flushes water quicker.

Yes, it will consume power but more horsepower is needed when you’re dealing with the easy-to-flood basement of yours.

Since it’s delivering by faster water evacuation, it’s a nice tradeoff. I’d say go for machines with at least 1/3 HP.

Remember to measure the usual depth of water in your basement, how deep are you going to set up the sump pump, powering options, and the width of the sump pit before getting a fix on the actual count.

Pick the Quietest Sump Pump Around

When you have a sump pump in the basement, it’s pretty easy to forget how much noise or vibration it makes.

Most of the pumps are quiet to begin with. They don’t make that much of a fuss. Yet, my advice would be to go for a quiet one.

Products from Wayne or Superior pumps are ultra-quiet. One can rely on them. From my experience, the noise ranges from 45 – 60 dBA. Humming or vibration isn’t a problem.

If you want to minimize the noise further, I have a detailed outline of how to reduce the noise of your sump pump. Feel free to check it out.

On the Quietest Sump Pumps

I’m confident that the quietest sump pumps will cut down on countless hours of maintenance and hard work for you guys.

Not only that, you’ll be able to cut down on the cost that accompanies regular maintenance as well.

This list will guide you to some of the most competent machines around. These things are cheap and effective as well.

No vibrations, no annoying noises, and peace of mind when you sleep at night knowing your house and all the precious furniture in it are safe from unchecked floods and contaminated water.

The buying guide is a good manual for people who are alien to the concept. Trust me, this article is a big step towards preparing you guys in case of an emergency.
