Having water all over the basement is nobody’s dream. No one has the patience or the time to monitor the basement regularly to check for water seeping through the cracks.
This is where sump pumps come in. Without them, we would not have the peace of mind knowing our basements will stay dry. This will most likely result in a slow buildup of anxiety or worry every time it rains.
In this buying guide, we’ll be looking at the best quietest sump pumps, what to consider before buying one, and the proper maintenance needed to keep your sump pumps well-functioning for years to come.
Our Picks for the Best Quietest Sump Pumps
These quiet sump pumps will make you feel at ease knowing your basement is going to be safe from the rain. These are the best quietest sump pumps on the market.
1. Wayne CDU980E 3/4 HP Submersible Cast Iron and Stainless Steel Sump Pump
Build: Cast iron with stainless steel
Capacity: 4600 gallons per minute
Solids Limit: N/A
The features of the Wayne CDU980E will make you think it’s too good to be true. Its incredible motor and self-protecting abilities make it one of the best quietest sump pumps on the market to keep your basement dry.
The Wayne CDU980E sump pump uses a combination of cast iron and stainless steel for its case. This is an ingenious way of making sure that the pump is sturdy enough (because of the cast iron) while being less prone to corrosion (because of the stainless steel).
Aside from the cast iron–stainless steel combo, we appreciate the compact design of this pump. This makes it lighter despite the fact it uses heavy materials.
An extra feature that helps reduce its weight is its lightweight impeller. This quiet sump pump also uses a polypropylene float that does not contribute much to the machine’s heaviness.
Another thing we love about this Wayne pump’s build is the fact that it is able to protect itself from damage through abrasion. This is done through the abrasion-resistant glass. With this feature, you would not need to worry as much about maintaining the unit because it takes care of itself.
For the prevention of blockage and air penetration, the pump’s cover is completely sealed.
The Wayne CDU980E sump pump features an automatic pump switch that is extremely quiet. You won’t have to worry about annoying noises caused by pump motors. This is a wonderful feature as a lot of pumps can do the job, but won’t be able to maintain the silence. This makes it stand out as one of the the quietest sump pumps you can buy.
It has a vertical float switch for this function and works well with sump pits that are at least 11 inches in diameter. It also has a waterproof power cord for safety.
When it comes to performance, it has a powerful ¾ HP motor, which makes it capable of discharging as much as 4600 gallons of water per hour.
As if that’s not good enough, this quietest sump pump also has a mechanism that disperses as well as filters debris. In effect, it would not need much cleaning and maintenance compared to most sump pumps.
As for installation, an experienced plumber would take only about 15 minutes to do the job.
Things to Note
Some customers report having problems with the floater mechanism of the pump. This does not happen often, but when it does, it’s hard to get decent customer support from the company.
In order to test the floater mechanism, pour water in the pit and see if this activates the pumping action.
You may want to ensure that the warranty is okay because if you buy this online, Wayne customer service representatives would almost always refer you to the Amazon team while the latter would advise you to consult with the makers themselves.
- Has abrasion-resistant glass
- Filters debris
- Easily installed
- One of the best quietest sump pumps on the market
- The materials used for the body are quite heavy
- May have problems with enforcement of warranty
2. Wayne VIP50 1/2 HP Portable Electric Pump
Best in Portability
Capacity: 2500 gallons per hour
Solids limit: 3/8 in.
If you’re looking for one of the most portable and quietest sump pumps that does more than keep water away from your basement, the Wayne VIP50 ½ HP is the one you’re looking for. This sump pump can be used to pump water from your pool, boat, or anywhere else thanks to its portability and garden hose adapter accessory.
This sump pump is made of thermoplastic casing, making it a sure win when it comes to preventing overheating and thus does not succumb easily to damage. Since thermoplastic is not prone to corrosion, the Wayne VIP50 can last as long as 15 years.
Since it’s made of thermoplastic, it also makes this sump pump handy and lightweight, unlike the other quietest sump pumps on this list that are built with cast iron or steel.
The pump is completely sealed, so you don’t have to worry about air or debris getting in the machine and affecting its performance.
This submersible pump is both electrical and manual. For the manual switch, it features a float one that is adjustable.
As to performance, with the help of its ½ HP motor, it has enough power to discharge 2500 gallons of water per hour.
As with other sump pumps, the discharge water capacity varies according to the discharge lift. At a 10-feet discharge lift, it can pump out 1550 gallons per hour. At 5 feet, it can carry up to 2000 gallons of water per hour and at 25 feet, 900 gallons per hour.
With its 1 ¼ in. discharge outlet, the Wayne VIP50 can allow solids up to 3/8 inches in diameter to pass through.
Things to Note
While the thermoplastic build makes this pump light and portable, it does sacrifice its strength in some ways. It was a bad engineering decision to secure the base with only 3 flimsy plastic tabs with screws.
This design flaw of this portable, quietest sump pump makes it prone to failing as the pressure created inside forces the bottom plate off.
Other customers do not experience this problem, but with the design employed, it is not unusual for the base to succumb to the pressure from the pump.
Another thing to note is that the Wayne VIP50 needs at least 2.5 inches of water before it is triggered. So if you need the automatic switch to turn it on at a water level below that, you may need to look for another pump.
Moreover, while this pump is designed to allow solids up to 3/8 diameter to pass through, we have to note that this is not always the case. The pump works really well for clear water, but it can easily get clogged up when there are bigger solids involved.
- Quietest sump pump for portable use
- Can be used for other household chores
- Has a garden hose adapter
- Based plate can easily give in to the pressure buildup
- Needs at least 2.5 inches of water to trigger switch
3. Zoeller M53 Mighty-Mate
Best Service Life
Build: Cast iron with thermoplastic bottom
Capacity: 1800 gallons per hour
Solids limit: ½ in.
From its first look, there is nothing special about this pump. In fact, it looks quite off-putting with its green exterior and bulky build, but with the Zoeller M53, there is more to it than meets the eye.
This submersible sump pump is encased in a cast-iron frame. This means it can last relatively longer than stainless steel pumps.
While the alloyed iron is heavier compared to a thermoplastic build, it does incorporate this material at the bottom. Overall, this pump weighs only 21 pounds.
The fact that the bottom is made of thermoplastic contributes to its decreased weight; however, heaviness is not the only problem that this technique mitigated.
Zoeller used thermoplastic in order to prevent heat conduction to the pump. Given that iron conducts heat very easily, the addition of thermoplastic at the bottom part solves the problem of too much heat conduction.
This cast iron–thermoplastic combination makes this pump a sturdy one without being too heavy. In addition, it is coated with an electrostatically applied epoxy powder that protects the cast iron design from rust.
This build makes it one of the best durable, quietest sump pumps you can get your hands on.
The Zoeller M53 has a horse rating of 1/3 and can run with 1550 rpm. It keeps your water-flooding and drainage system problems in check with its 45 gallons of water per minute capacity. The flushing out rate varies according to the discharge lift this submersible pump is installed.
At 10 feet, it pumps out 2040 gallons per hour. At 15 feet, the flushing capacity decreases to 1140 gallons per hour.
As for the switch, this pump has a vertical float switch and an automatic switch which can trigger every two or three minutes, depending on the water level.
The power cord is nine feet long and is powder-coated. As an additional safety feature, the cord also has a waterproof cover.
The discharge pipe measures up to 1 ½ National Pipe Tapered (NPT). It can allow spherical solids that are up to half an inch in diameter to pass through.
With its utilization of quality materials, the Zoeller M53 Mighty-Mate can last from 2 to 4 years before it will need replacement.
Things to Note
The most common issue about this pump among customers is the fact that it uses a runner float instead of a plastic one.
Rubber has a tendency to solidify as it gets older. To remedy this, Zoeller employed silicon grease. This works fine for some, but some users report that it easily gets damaged.
In connection to that, the switch is also not adjustable and is too short for average sump pits. This results in an accumulation of about 4 inches of water at the bottom of the pit.
Another thing to take note of is the fact that this pump is not compatible with a Ground Fault Circuit Interrupter (GFCI) circuit.
Check if you have this kind of circuit in your basement first. If you do, you need to make new installations that are compatible with the pump.
- Made of heavy materials
- Body is coated with epoxy that helps prevent corrosion and damage
- Rubber float has tendency to solidify overtime
4. Flotec FPPM3600D-01/09 1/3 HP Pedestal Sump Pump
Capacity: 3480 gallons per hour
Solids Limit: ¼ in.
If you ever need an affordable and reliable backup sump pump, the Flotec FPPM3600D may be the one for you. This pickup might surprise you as one of the best quietest sump pumps that’s budget-friendly.
With a thermoplastic pump construction, this sump pump is lightweight and corrosion-resistant. To be specific, it weighs only 11.3 pounds, which makes it a breeze to install. This machine requires a 12-inch diameter pump basin.
As a safety feature, its electric motor is protected by a built-in thermal overload circuitry. The power cord is also long enough at 6 feet.
This Flotec sump pump offers a 1 ¼ discharge pipe diameter. With its 1/3 HP motor, it can deliver up to 3840 gallons of water per hour at zero lift and up to 2460 gallons per hour of water for a 10-foot head.
For its automatic switch, it employs a metal float lever. This is a great feature since the float can be easily adjusted to fit the depth of most sump pits.
This is a great backup water removal pump to have around just in case your main pump malfunctions.
Things to Note
The thing we love most about this pump is its durable design.
It can last even up to two decades for some. We observed that people who replaced their old units for the same model did not experience the same quality with the replacements.
We can’t be certain what caused this. Perhaps the quality control is not as strict as before. If you choose to purchase this particular model though, make sure your warranty is in place.
In addition, even with a thermoplastic case, the pump uses a corrosive material for its plates. Since this part is exposed greatly to moisture, it’s prone to rust over time.
- Automatic switch can be adjusted according to depth of sump pit
- Corrosion-resistant build
- Has built-in thermal overload circuitry
Plates are prone to rust
5. Wayne WSS30V Upgraded Combination 1/2 HP
Build: Cast iron base and steel body
Capacity: 5,100 gallons per hour
Solids Limit: N/A
If you want a two-in-one sump pump, this is at the top of our buying guide recommendations. The Wayne WSS30V has a backup water removal pump that runs on a 12V DC connection. This can remove up to 10,000 gallons of water in a single charge.
The alloyed cast iron base, along with the stainless steel body, makes this pump heavy. At 35 pounds, it may require more effort to install compared to the other quietest sump pumps in this list. To slow down the process of corrosion, the iron is epoxy-coated.
Although the main pump is made up of heavy materials, the backup system is made up of thermoplastic, so it doesn’t add much to the weight of the whole unit.
This sump pump can also be installed in a 15-inch sump pit.
This Wayne pump has a unique top suction design that reduces clogging and prevents air lock. As for the switch, it employs a vertical float made of polypropylene. This material is solid, leak free, and is reliable enough.
The pump can carry up to 5100 gallons of water per hour at zero lift. It then decreases to 3480 gallons per hour of water at 5 feet and to 3480 at 10 feet.
The great thing about this pump in regards to power is that it can still work even at a 20-feet height.
Seeing as how this is a combination type sump pump, it also has an alarm mechanism that alerts the owner when the pump is using the 12V battery.
It also provides a visual way of determining when you need to recharge the pump. The monitoring system in place consists of LED lights (red, yellow, and green). These colors indicate the status of the battery.
The backup battery can provide up to 26 hours of continuous protection from flooding, which is more than enough to recharge the battery.
Things to Note
The LED lights are a great way to let you know about battery status. Many users though have observed that the light indicators are not reliable. It stays green even though the battery needs to be charged and only turns red at the last minute.
- Designed to prevent airlock
- Can work effectively even at a 20-feet discharge height
- Backup battery can last up to 26 hours
- Comes with a backup water removal pump
- Made of heavy materials
- The light indicators do not provide an accurate reading
What Is a Sump Pump and How Does It Work?
A sump pump is a machine that directs water away from your basement to keep it from flooding during rainy seasons.
It is a must-have investment if you don’t want to deal with the mess of a water flooded basement that can cost you more in the long run.
A sump pump is usually installed in a pit, which is a hole in the ground about two feet deep. It works by detecting water increase in the soil and pumping the excess water out before it can get into the building.
From there, it dispenses the water to a safe distance away from the house.
These pumps work using centrifugal force, directing the water to the sides. By doing so, they create a void in the middle with lower pressure, causing the extra water to fill it.
The water is then pushed through the pipes where the water is carried off to another location, which is usually 10 to 20 feet from the house.
Things to Consider Before Buying a Sump Pump
Before buying a sump pump, it’s important to consider the type, switch, and the make of the pump.
There are four main types of sump pumps usually used for residential purposes: primary, battery backup, combination, and sewage.
The most common sump pump type is the primary sump pump, which is further categorized into submersible and pedestal sump pumps.
A submersible sump pump is installed with the actual pump inside the pit. Pedestal pumps, on the other hand, has the pump on a stand, positioning the actual pump away from the water.
The battery backup sump pump can work for hours even without electricity because of its backup power.
The combination kind is a mix of the primary and the battery backup pump. Thus, the primary pump works when there is AC power available, but the other one kicks in, in case the power is lost.
The sewage pump, on the other hand, can handle a larger solids with the water and is usually for sewage water systems. Although, you can still use them like ordinary sump pumps.
There are three types of switches when it comes to sump pumps: tethered float switch, vertical float switch, and electric float switch.
Tethered switches are the most long-lasting among the three, but they require a bigger sump pit. You may have to increase the diameter a few feet more. A tethered switch may be a hassle, but it’s only at the beginning.
Vertical switches won’t require a large sump, but it has a relatively shorter life span compared to the tethered switch.
Electric switches don’t have moving parts that will get stuck during the job. Electric switches, however, are prone to get affected by foreign materials in the water.
The make of the pump’s housing should be given attention especially in a submersible sump pump. Thermoplastic is a good choice since it makes the whole system lightweight, making it easier to carry and set up.
Cast iron is heavier than thermoplastic, but it can last relatively longer. Stainless steel, on the other hand, is even heavier and can corrode more easily, which is why we suggest staying away from these pumps if you can.
This article is all about recommending the best quiet sump pumps, so it’s also important to discuss what makes the pump produce these noises.
Here’s the rule of thumb: the bigger the motor and horsepower are, the louder the pump will be.
There is no completely quiet sump pump, but you have to determine the noise levels you deem acceptable. This way, you can actually sleep soundly while the machine takes care of your basement problems.
How to Maintain Sump Pumps
Owners should check their sump pumps regularly. This should be done at least once a year and more frequently during the rainy seasons.
It is recommended to fill the sump pit every once in a while to see if the pump still works.
Another reason for doing this is to avoid corrosion of the impellers: If there isn’t enough water to trip the switch, the pumps’ trigger won’t activate. This causes the impellers to remain submerged in water for long periods if the pump is not activated.
It is also a good idea to install an alarm near the sump pump to alert you when the pump is not working.
Most of these alarms are also triggered by floatation switches but are much higher than those of the sump pump.
The alarms produce buzzing noises that you can hear anywhere in the house to let you know your pump has stopped working and that you need to resolve the problem yourself.
Furthermore, to avoid any untoward incidents of electrocution, it’s wise to install a ground fault circuit interrupter. This convenient equipment is designed to shut off electric power whenever there is ground-fault.
It’s also important to choose the installation location wisely to avoid accidents.
