A sump pump is a key component of any home. It keeps your basement dry by pumping water out of your home into a drainage system. But it’s not always silent. It can be loud, noisy, and sometimes create a lot of vibrations that disturb your home.

If that’s the case, you might need a quiet check valve for your sump pump. That’s why we researched and compiled this list of the 5 best quiet check valves for sump pumps so that you can choose the best one that suits your needs. We’ve tested them out and rated them based on their performance, quality, and value.

Buying Guide

When it comes to your home’s plumbing system, there are three primary components that make up the foundation:

  1. The sump pump,
  2. The sump pit, and
  3. The sump pump check valve.

A sump pump is basically a battery-powered motor that can pump out water from a sump pit. This is typically where the basement floor drains into. The pit itself has a grate on top, through which water flows into the pit. Once in the pit, the water is pumped out by the sump pump, which is connected to the pit. The sump pump check valve is usually found at the bottom of the pit. This is where the sump pump draws air from the outside environment and pumps it into the pit. This helps to prevent any water from backing up into the house or outside environment.

Noise And Sound Level

While it is important to know the sound level of your pump, it’s also essential to consider the noise level. If you are using your sump pump on a daily basis, it’s important to get the noise level right for your needs and your neighbors.

The best way to do this is to find out the decibel level of your pump and compare it with the decibel level of your home. The American National Standards Institute (ANSI) defines the sound level in decibels as:

Decibel level = 20 log10 (sound pressure level / reference pressure level)

The reference pressure level is considered to be the level of sound pressure in a quiet room. The higher the decibel level, the louder the sound.

The sound levels of pumps can range from 60 to 90 dB. However, if you want to be certain that your pump won’t disturb your neighbors, it’s best to get a pump with a decibel level of no more than 75 dB.


It’s important that you install your sump pump correctly, and keep track of any maintenance that might be needed.


There are three types of capacity:

  1. Single pump,
  2. Dual pump, and
  3. Triple pump.

Single pump: This type of sump pump usually has a capacity of 500 gallons, 1,000 gallons, or 2,000 gallons. They’re typically easy to install, but have less capacity than the other types.

Dual pump: These are usually located in an exterior location, as they require a lot of space. They also come with a higher capacity than single pump models.

Triple pump: The third type of sump pump is the most expensive, and are generally only installed in large homes or commercial buildings. These pumps can easily hold a capacity of 5,000 gallons or more.

Flow Rate

When it comes to flow rate, there are two different options:

  1. Continuous, and
  2. Intermittent.

Continuous flow rate: When you turn your sump pump on, the water will continue to flow until the sump pit fills up, which can take anywhere from a few minutes to several hours.

Intermittent flow rate: This type of sump pump has a “cycle” that allows the water to drain from the pit for a set period of time before it begins again. It’s typically used in smaller homes.

Drainage Direction

It’s important to know what direction your sump pit drains. There are three options:

  1. Up
  2. down, and
  3. Both.

Up: This option is the most common, as it drains water out of the pit and into your basement.

Down: This is useful for homes with sloped or uneven floors, as it drains water from the pit away from the foundation.

Both: This type allows for both up and down the drainage, depending on the level of water in the pit.

Inlet Pressure

Your sump pump will need to draw air from the outside environment to pump out the water from the pit. To do this, it needs a certain amount of pressure. To determine this, multiply the size of your pit by the height of your basement floor. For example, if your pit is 5 feet deep, and your basement is 8 feet tall, then your pressure should be 8 x 5 = 40 pounds.

Outlet Pressure

The outlet pressure of your sump pump will also have an impact on how loud it will be when it operates. There are three options:

  1. Low,
  2. Medium, or
  3. High.

Low: Low outlet pressure usually makes for a quieter sump pump.

Medium: Medium outlet pressure is most commonly used for smaller homes or those with small sump pits.

High: High outlet pressure is typically only used in larger homes, as the pumps can get loud enough to cause problems.


There are two different materials you can use in your sump pump’s pit:

  1. Concrete, and
  2. Steel.

Concrete is generally recommended for most situations, as it is easier to clean and maintain.


Is there a quiet check valve for the sump pump?

Yes, there are several quiet check valves available for your sump pump. Some of them are made out of stainless steel, and others are made out of plastic. They also come in different sizes, depending on your sump pump’s requirements.

How can I make my sump pump quieter?

You can use an electric motor or a small pump with a fan attached to it to help create a more quiet sump pump. You can also install a venting device such as a sump drain to prevent flooding when the pump fails.

How does a quiet check valve work?

A quiet check valve works in such a way that it allows liquid to flow while preventing air from flowing. It is a passive component, which means that it doesn’t need any power to function. The valve consists of a rubber disk and a metal chamber that is filled with water. When the water inside the chamber is heated, it expands, thus allowing the liquid to flow through the valve and out. As the temperature decreases, the water contracts, thus stopping the flow.

Where is the best place to put a check valve on a sump pump?

You can use a check valve anywhere on your sump pump. But if you want to minimize the chances of any damage, then it’s advisable to put it on the pump itself. Check valves are most commonly found on the suction side of the pump, but you can find them in the discharge as well.

Is a check valve better than a ball valve?

A check valve is more effective in preventing water from flowing backward, while a ball valve has a more complex design with multiple parts. If your pool is equipped with a filtration system, then a check valve will work better for your needs. On the other hand, if you have no filtration system, then a ball valve might be better. It’s important to note that a check valve is not foolproof, and can fail at times.

Is it possible to use a rubber check valve for a sump pump?

Yes, you can use a rubber check valve for a sump pump. But be careful with them, because they can get damaged if you leave the water inside them too long. So, keep an eye on it periodically and drain the water regularly.

Does a check valve stop water from going down a drain?

No, a check valve doesn’t stop water from going down a drain. It’s designed to prevent the reverse flow of water. This means that the valve only lets water through one way, so it does not let the water go down a drain. This is useful for sinks, showers, and washing machines, as it prevents them from backing up or overflowing.

Is a check valve really necessary?

A check valve is a simple device that allows fluid to flow in one direction only. In the case of pool heating systems, it prevents water from flowing backward into your pool, which can cause damage or harm. It’s also a safety device that ensures that the pump will not fail if the system is reversed.


So you’ve just installed a new sump pump? Great! You’ll be glad to know that you’re now equipped with one of the most powerful pumps available. But if you want it to last a long time and work efficiently, it’s important that you install the right check valve for it. This is the most important component of your sump pump system, and it can literally save you thousands in repairs and replacements.

Now, while many manufacturers offer check valves, we recommend the best quiet sump pump check valve. It’s a high-quality product, and it has a strong reputation among consumers. It’ll ensure that your sump pump works for years without ever having to get repaired again.
