Did you know that around 65% of homes in America suffer from wetness below the ground? Besides, many homeowners get a flooded basement at some point. Moisture that water causes can lead to mold and mildew, as well as various health and breathing hazards over time. That’s why some people use quietest sump pumps. These devices are installed at the lowest part of a basement to keep the area under the house dry. Pumps are usually installed into specially constructed pits, and they pump the water away from the building.
Today, there are various sump pumps on the market. Some do the job flawlessly, but some are not that great. Choosing the right water pump might be a tricky job, so that’s why we have prepared this article for you.

7 Quietest Sump Pumps: Comparison Table
We have tested many pumps over the years, and in this article, we present you with our top picks!
Top 7 Quietest Sump Pumps: Reviews
The water pumps on this list are carefully chosen among many that we tested. Of course, choosing the right one depends primarily on your needs, but we’ll talk about that, too.
1. WAYNE CDU980E Stainless Steel Pump
Several things made us consider this pump for review. At first, let’s mention that Wayne is a popular sump pump manufacturer with over 80 years in business. The CDU980E model is the one that people talk about the most when it comes to Wayne pumps.
This model comes with a ¾ HP engine, and a very durable, solid cast iron body. It can pump up to 4600 gallons per hour at 0’ and is ideal for large areas.
We are amazed by the power it produces, compared to its size. The pump has a vertical switch, designed for a large sump basin.
It offers a mesmerizing quality, in areas where other pumps might give you troubles.
While some parts of the pump are made from stainless steel, the impeller is made from polycarbonate. It’s not only corrosion-resistant but also throws the water at a very good pressure. This pump has one of the best body designs, among many units on the market.
Yet, the best thing about this device is thermal insulation, which makes it a high-end performer. Compared to other similar pumps, it won’t heat so quickly, thus improving the run-time and lifespan of the device. Besides, the portability of CDU980E is unmatchable, so you can easily carry it anywhere.
The pump doesn’t have many disadvantages, but let’s mention some that we found. At first, the handle is a bit small, so it’s difficult to change the position while it’s working. The cord is also small, so you might need additional cable if your power supply is too far. The price is also a bit higher, but it’s still fair, considering the functionality and quality.
If you want a high-quality pump that comes in a sturdy and durable body, this is your best choice. It does its job efficiently and effortlessly and promises a long lifespan. The customer support team is quick and professional, which is another big plus!
| Pros | Cons |
| High-quality, durable body | Slightly pricey |
| Thermal insulation | Small handle and short cord |
| Very portable | |
| Excellent for large basements |
2. Superior Pump 91570
This sump pump is top pick according to many customers. It comes with an excellent, ½ HP motor that pumps around 3300 gallons per hour. Besides, the thermoplastic body prevents corrosion from water, chemicals, and various harmful substances. It’s ideal for most basements, and on top of all that, it is very affordable.
The pump has a ¾-inch garden hose connection, in case you need to do flushing and cleaning. Also, it has a 1.5-inch discharge for large capacity drainages.
The pump’s filter is of high quality and perfectly separates large debris and prevents clogging.
According to the manufacturer, if you mount and use it properly, it will operate daily for more than 10 years.
The 1-year warranty covers any possible problems with workmanship and quality, but we doubt that you will need to make any claims.
The only thing we don’t like about it is the lack of an automatic switching system. However, having its price in mind, this pump is still among our top choices.
Superior Pump 91570 is excellent for people who need a powerful unit at an affordable price. If the lack of an automatic switching system doesn’t seem to be a problem for you, 91570 is an amazing choice.
| Pros | Cons |
| Strong and durable | No automatic switching system |
| Ideal for both flushing, cleaning, and large-capacity drainages |
3. Superior Pump 92341
In some situations, you might require a pump that can do lots of work for a short time. Or, a pump that can do normal work, but consistently. In both cases, you would need a strong and reliable device. Theoretically, this pump seems to be the ideal choice, so let’s see what it has to offer.
With the vertical float switch and ⅓ HP engine, 92341 is a pump that can suck 45 gallons of water per minute, and start the work sooner. It translates to 2700 gallons of water per hour at 0’, which is pretty decent.
The quick trigger makes it ideal for tough situations, such as the covering of the pool after a heavy storm. However, with around 9 kilograms in weight, it’s not the most portable pump out there.
With 4.1 amps, the device is designed to be energy efficient. It means that the design directly affects its longevity, and each part is factory tested. The pump also comes with a 10-foot long cord, which is enough in most cases.
Like any other device, Superior Pump 92341 has a few small drawbacks. The first that we noticed is its weight. As mentioned, it weights around 9 kilograms, so it can be exhausting if you need to move it frequently. Also, a pump has a little trouble handling sediment that may be sucked in during the cleaning process. You can solve the problem by leaving the pump in a bucket with a few holes in the bottom.
Shortly, Superior Pump 92341 is not the best sump pump on the market. However, it’s the best in terms of value and money. You will get exactly what you pay for. Besides, according to many customers, this pump will serve you for a long time, with almost no maintenance costs.
| Pros | Cons |
| Excellent ratio of price and quality | The pump is a bit heavy, compared to similar pumps |
| A decent motor power |
4. Zoeller m53 Sump Pump
Zoller m53 might be on a slightly expensive side. Yet, if used properly, it can serve you for the next 20 years, without any major problems.
Model m53 is a submersible sump pump and comes with a ⅓ HP. It has 2580 gallons of water per hour flow rate and is backed by a 3-year manufacturer warranty. The pump doesn’t have a backup battery, and it runs on 115 volts, consuming between 5 and 10 Amps.
At first glance, Zoller m53 might look like a classic old pump. However, it has a strong and sturdy body, designed to last for a long time. Also, it’s pretty portable and has a nice, compact metal handle. You can carry it around at ease.
The body is made completely of cast iron, which allows heat to quickly disperse. It provides extra safety to the internal parts, which are already protected with strong material.
Besides, the material is dried with epoxy which is excellent at preventing corrosion, similar to stainless steel.
The main exterior parts of the pump are the power cord, discharge, and the handle. The power cord is three meters long, which is pretty decent. It’s also safe and strong, made of quality material. Also, a ½-inch NPT discharge can fit any standard pipes or PVC and has the ability to remove up to half an inch of debris.
We have to mention that its motor is rated as one of the best in the pump industry by plumbing experts. It’s a 4-pole motor that produces ⅓ HP at 1550 RPM, and also comes with an overheating switch. Besides, you don’t have to worry about oil leakage. Thanks to the ceramic and carbon shaft seal, the oil is completely secured.
Buying a sump pump can be a lifetime investment. Zoeller m53 costs a bit more than average but provides exceptional durability and high quality. If you want a smooth-working unit that will serve you long, this sump pump will be your best choice.

This pump comes with a ½ HP motor, which perfectly sucks up to 3600 gallons of water per hour. Not only that, but it’s able to handle liquids up to 180-degrees Fahrenheit, which is immersive.
Another thing that we like about model 92551 is its construction.
It’s made of cast iron and comes with a stainless steel drive shaft (non-corrosive), impeller, and a float ball. It’s obvious that the pump is built to last since each component is 100% factory tested.
Moreover, it’s CSA certified, which is always a nice thing to see.
We noticed only one downside about this pump. When you take it out of the package, it might require a bit of assembly until you can run it. The assembly process is not complex, but might be difficult for people who are not experienced with DIY stuff.
Buying this pump is a pretty good investment. It comes with an excellent motor and relatively low price, with the parts being strong and durable.
| Pros | Cons |
| Excellent motor | Requires a bit of assembly before the first run |

6. Wayne VIP50
Several things convinced us to take VIP50 for review. At first, it can pump up to 2500 gallons per hour, and pass leaves, pebbles, and dust without clogging up. It might not sound like a big deal, but keep in mind that it costs less than $80, which is amazingly affordable.
The pump is made of a glass-reinforced thermoplastic and comes with a corrosion-resistant impeller. Also, if you need to transport it, don’t worry – it has a pretty nice handle that makes it completely portable.
VIP50 comes with nice internal protection to improve its lifespan. For example, it’s fitted with thermal protection that turns off the pump in case of overheating.
However, on top of all the good stuff, it comes with a relatively short, 8-foot power cord.
Wayne VIP50 is an excellent choice if you are looking for affordability, quality, and portability in a single unit. It doesn’t come with an amazing sucking power, but it’s fantastic considering the price.

| Thermal protection | Not ideal for big floods |

CDT50 is an excellent choice if you are looking for a powerful unit. Although it has a ½ HP motor, it can pump up to 4200 gallons per hour. Besides, it’s assembled in the US, with both foreign and domestic parts.
With durable cast iron housing, CDT50 is excellent for heavy-duty. It offers reliable operation while producing a low level of noise. Similar to the previous model, it successfully eliminates air locks and clogging.
The pump offers a cast iron and epoxy-coated stainless steel construction, which grants for its longevity. On top of that, you also get a 2-year warranty, which is another confidence boost.
Mainly due to construction materials, the pump is a bit heavy. With almost 10 kilograms, it might not be the most portable solution on the market. However, it comes with a nice handle, which slightly improves the portability.
The Wayne CDT50 is an ideal unit if you primarily need power. With strong construction, it’s ready for any heavy work, while the 2-year warranty ensures trust among customers.

Quietest Sump Pumps: Buying Guide
If you never owned a sump pump, buying one can be a bit tricky. There are various features and hidden flaws that you have to consider before making the decision. Therefore, the sump pump is ideal only if it satisfies your needs, which vary from person to person. Let’s take a look at the things that you should have in mind when buying one.
Main Features and Benefits
There are several benefits that quietest sump pumps provide. Besides preventing the flood, they prevent the peeling of wall paint and algae growth. They also protect the foundations of buildings, which is another plus.
Prevents Peeling of Wall Paint
Quietest sump pumps are excellent at collecting lots of water in a short time. Since most of them have auto-switch, you don’t have to worry about noticing the flood too late. But what might happen if you don’t have the sump pump, and don’t notice the water immediately?
The water would seep into the walls and cause the paint to peel off. Moreover, in some cases, mortar and cement can also peel off, exposing the bricks. In the long run, it can cause serious damage, which is usually difficult to repair.
Prevents Algae Growth
Algaes almost always grow in places with continuous water presence. The worst thing is, they grow fast, and cause hazardous damage. At first, they can make the floor slippery, which is, obviously, not a good thing to happen. Besides, algae are ideal for insects that thrive for wet environments. They also absorb pesticides, which can lead to long-term problems with insects, and make the basement unusable.
Lastly, algae produce various toxins. They might not be too harmful to us, but can be hazardous for small animals. In some cases, pets can even consume algae and become ill.
Protects Buildings Foundations
Maybe you didn’t know that the water below buildings is not always static. Even in dry seasons, the water is pushed by rocks. Over time, it can push through concrete, which is water-resistant and eventually break through, flooding the basement. In the long term, it can even affect the stability of your house.
How Long Do Sump Pumps Last?
Usually, the sump pump can last for around 10 years. Some great, high-quality models can even last longer. However, there are a few things that you should consider.
First, if your pump is over 7 years old, you should know that it might stop working anytime. Especially if it’s been working hard and frequently for long periods.
Also, if the pump gets corrosion and rust, you should take care of it as soon as possible. Over time, it can go deeper and cause irreparable problems.
In the end, if your home has frequent power outages, it can directly affect the lifespan of any device. It’s a nice idea to buy a backup power system for your pump. On the other hand, some good models already come with built-in surge protection.
Kinds of Switches
Switches make the primary connection that controls the sump pump. If they are damaged or defective, it usually leads to a malfunction of the switch. There are four types of switches, which are vertical, diaphragm, tethered, and electronic.
Vertical switches are very simple to install and adjust. They are ideal for most common sump pump models and work on a very simple principle. As the water level in the basin rises, the float rises as well. When it reaches a particular level, the switch is activated. Therefore, when the water level falls, the pump turns off.
Diaphragm switches are activated by pressure. As the water level in the basin rises, it increases the pressure, which compresses the bladder in the switch. When the bladder is compressed enough, it activates the pump.
The tethered switch has a specific spherical float, with a stainless steel ball inside. It’s attached to the basin with a cord, so when the water level rises, the cord extends. Depending on the cord extension, the pump will turn on or off.
Electronic switches are still new and have minimal or no moving parts. There are various models of electronic switches, depending on how they work. Although they are still new, electronic switches are becoming more and more popular. The main reason is the lack of moving parts, which directly affects their durability.
What Amount of Power Do I Need?
When talking about the power of quietest sump pumps, people usually talk about horsepower. For most average-sized homes, a pump with ⅓ HP would be enough. However, if you have an above-average water table, you should choose a model with ½ HP.
In the end, if you live in a high water table area, you might need a pump with ¾, or even 1 HP. Those units can pump lots of water per hour, and provide a mesmerizing power.
Noise Levels and Decibels
Like any other mechanical unit, quietest sump pumps also make noise while working. Although newer models are pretty quiet, some older pumps can get very noisy at some point. But what is the cause of a noisy sump pump?
As the water moves through the pump, it pushes the air out. It’s the source of minimal noise that every pump has, and it’s usually not a big problem. However, a sump pump can get really noisy, due to several different reasons.
A Noisy Motor
Although most pumps are made of cast iron, there are also units made of PVC or plastic. Those usually generate more noise, and it isn’t much you can do about it. Some new models even have self-lubricating motors, which allows them to run more quietly and require less maintenance.
If you are looking for a new, quiet pump, you should opt for cast iron models with self-lubricating motors. It’s also desirable if the motor is below the sump basin.
Gurgling Noises
If your pump makes gurgling noises, it’s because of water that flows back through the discharge pipe. There are a few things that you can do about it.
At first, you can replace the standard swing check valve with a spring-loaded check valve. It will allow the water to flow more evenly, and therefore reduce gurgling.
Another thing you can do is to adjust the pump switch. If the pump runs while the basin is empty, it will produce unpleasant noises. You can adjust it to stop running before the basin is completely empty, and prevent the trouble.
Vibrations and Clanging
When the water is discharged through the system, it causes specific noise. It occurs when the pipe hits the pump’s basin and can be unpleasant at some point.
The first thing to do is to wrap the insulation around the pipe. It will dampen the noise when the pipe hits the basin or wall. Although it’s a simple trick, it can be very helpful.
You can also put rubber grommets on the underside of the pump’s lid or cover. It will help reduce vibrations and even the noise of motor rattling.
Quietest Sump Pumps: FAQs
Both options are good. Pedestal pumps are usually cheaper since they draw less amp. On the other hand, pedestal pumps are more difficult to cool in small spaces, so you should consider that, too.
In most cases, sump pumps fail due to electricity problems. You should always plug it directly into the outlet, without the extension cord. The outlet should also be on a separate circuit breaker.
That’s not a good idea. At first, the salt from the water softener can cause seals, screws, and even the motor shaft to corrode. Also, the chemicals from laundry water can damage the pump’s seals.
Quietest Sump Pumps Reviews: Conclusion
As you can see, choosing the right quietest sump pumps depends mainly on your needs. You can’t go wrong with any pump from the list since Water Filters Advisor have carefully chosen the best units on the market.
