5 Best Quietest Sump Pump

In this section, we have presented the details of the best quiet sump pumps out there. You can have a thorough look or just go through the advantages and drawbacks of them.

1. Superior pump 91250 1/4 HP Thermoplastic

Usually, pumps that are quiet and compact do not come with a high suction or pumping power. However, it would be wrong to say the same for the Superior  91250 utility pump. First of all, the product features a thermoplastic construction that is able to resist corrosion to provide years of service. The build would have backfired in the long run if the internal components were not made with quality materials. However, that’s not the case. It features stainless-steel shaft seals, copper motor windings, electronic split capacitors, and a motor plate with double seals. Additionally, the pump offers a high-flow impeller and a removable intake screen, able to filter out debris and solids of 1/8-inches.

On the other hand, the ¼ Hp sump pump packs a decent punch when it comes to pumping water. It can lift about 1800 gallons per hour when in contact with water. Also, the pump can lift water from a maximum vertical distance of 25-inches. The utility pump has an NPT discharge rate of 1/4-inches and a garden hose adapter of 3/4-inches. It also comes with a 10-inches power cord, which is long enough for most jobs. One final thing about the pump is that it is compact and features a carrying handle, making it extremely portable.

2. WAYNE CDU980E 3/4 HP Submersible Sump Pump Cast Iron

If your ultimate goal is to have a pump that features noiseless operation with a high pumping rate, then have a look at the WAYNE CDU980E ¾ HP submersible pump. The ¾ HP motor is not just a show. This pump is a literal beast when it comes to lifting water. It can pump water at a rate of 3500 GPH at 20ft distance, 4100 GPH at 15 feet, 4600 GPH at 10, and 5490 at 0 feet.

Do not be deceived by its size; it may look small, but it is certainly not weak. Initially, the pump features a thermoplastic housing. It allows the pump to resist corrosion and overheating problems; however, it makes the pump vulnerable to heavy impacts. So, take precautions while moving the pump from one place to another.

Quietest Sump Pumps: The Ultimate Buying Guide

There are a few things of consideration that require your attention before you can purchase a quiet sump pump. These features can aid you in choosing an optimal product for your home.


To be honest, there are no sump pumps that don’t produce a single sound. All of them will create at least a little bit of noise. However, the noise level may vary according to their motor sizes and build. In the past, pumps used to feature PVC housing, which used to create loud noises. However, the modern sump pumps are much quieter due to their thermoplastic or cast-iron construction. Hence, a pump featuring a cast iron or thermoplastic body should be your first choice.

On the other hand, motor sizes also come into play in the production of noise. A large motor will be more powerful and noisier compared to a small motor. Therefore, if your primary objective is to lift a massive amount of water, then a sump pump with a large motor should be your go-to product. There are ways to make your big pump quiet, but more on that later. If you are planning to work with shallow pits, then a small motor will be more than enough for you. It won’t produce too much noise, and you can have a smooth operation.

Pump Build

It is extremely important to consider the construction of your sump pump. It will determine how long the product will last. We already mentioned that cast-iron pumps operate quietly. They are also able to resist abrasion. On the other hand, thermoplastic build ensures resistance against corrosion and offers a lightweight body.

Stainless steel is less prone to rust than cast iron, but they are quite heavy in comparison to the thermoplastic body. Your ideal pump should have a cast-iron build or a combination of both cast iron and thermoplastic. It will resist corrosion, abrasion, and overheating while producing a minimum amount of sound.

Sump Pump Types

Usually, the choice is between a submersible and a pedestal pump. Pedestal pumps come with a motor, which is situated above the ground, creating more noise and obtrusion. On the other hand, submersible pumps are usually placed underwater; therefore, it creates less sound. So, for noiseless operation, submersible sump pumps should be your product of choice.

Power Source

Generally, pumps use electricity to run. However, power outages or pump malfunctions are very common incidents that can happen anytime. So, when purchasing a sump pump, you should also consider the power requirements of the product. A battery-operated sump pump can be very useful if you have frequent power outages in your area.

How to Make Your Sump Pump Quieter

There are a couple of reasons which can make your pump produce unwanted noise. The fixes are quite simple, but it’s difficult to pinpoint the cause of the problem. Without further ado, let’s look at the causes and fixes of sump pump noise issues.

Motor Producing Noise

Sometimes, the motor of your pump may produce excessive noise, and in order to fix that, you may need to change the housing to cast iron or lubricate it adequately. Other solutions are changing the pump to a submersible one, or you can place a cover to reduce the noise. Placing a cover will muffle up the noise, but it won’t completely block it.

Slurping Noise

The slurping noise would be the same as liquid being sucked with a straw. It happens due to a lack of maintenance. You can fix the problem by conducting regular maintenance. You should also make sure the pump is submerged under a few inches of water to reduce slurping noises.

Excess Vibration

When the discharge pipe is in contact with the sump pit or a nearby wall, it causes the pump to produce vibration noises. The fix to the problem is quite simple. You can use rubber grommets to align the pipe. On the other hand, you can also try using foam insulation to wrap the pipe. Only wrapping the place of contact would be enough to stop the vibration.

Gurgling and Clanging Noises

Clanging noises require the same solution we have mentioned for excessive vibrations. Gurgling noises, on the other hand, are produced when water flows irregularly through the discharge pipe after each pumping cycle. The solution to the problem requires upgrading the standard check valve with a spring valve. This will enable the water to travel more freely and evenly.

Also, make sure to adjust the float switch in a manner where the pump won’t completely drain the sump pits.


1. What is a Quiet Sump Pump Check Valve?

Quiet check valves are used for silent pump operation. It is almost the same as standard check valves but comes with a hinged, spring-loaded flapper mechanism. The spring causes the flapper to close when the pump is turned off, stopping the liquid flow. The mechanism eliminates reverse water flow, which puts an end to the noise produced through hydraulic shock.

2. What Makes a Sump Pump Quiet?

A cast-iron construction can make a pump quieter than other ones. Moreover, a small motor produces less noise and vibration, making the pump silent. Also, the addition of a quiet check valve can further help in making a pump quiet.

Final Verdict

Some people get accustomed to the noise of a sump pump, while some just cannot tolerate it. If you are from the latter group, you shouldn’t let a pump mess up the relaxing environment of your home. Even if it doesn’t bother you at first, it may start doing so one day. Take our advice and prevent it before happening. In our review of the quietest sump pumps, we have discussed almost everything that may concern you. So, do not wait for the inevitable and get that solution to your problem right away.
