 How to Quiet a Noisy Pool Pump

The pool pump is one of the essential components of your swimming pool. The pool pump helps circulate water in the pool. However, the pool pump can make loud noises that will irritate and ruin your mood. It can even make your relaxation and swimming in your pool seem not enjoyable.

How to quiet a noisy pool pump. Some of the simplest and most effective ways to quiet down your noisy pool pump are; cleaning up the skimmer baskets, setting up anti-vibration pads, adjusting the base of the pump, setting up the pool cover, and replacing worn-out bearings. 

In this article, we’ll talk about these in detail and a few other methods to help you quiet down your noisy pool pump and stop the noise from disturbing your family and neighbors.

13 Ways to Quiet a Noisy Pool Pump

Below are some ways you can use to assist you in quieting your pool pump.

Adjust the Base of the Pool Pump

One of the reasons why your pool pump might make an unusual noise is that the bolts holding the pool pump to keep it steady may be loose.

To figure this out, you will need to turn on the pump and allow it to run as you look out the base for any vibrations. If you realize the base vibrates while the pump is running, then it means that the bolts keeping the pump steady are loose.

To mitigate this problem you need to switch off your pump and use an adjustable wrench to tighten up the bolts. Switch on the generator when you’re done to see if the noise has stopped. If you realize the noise hasn’t stopped then you need to turn on the pump again and unbolt the bolts that hold the pool pump and attach concrete pads to it.

To get going you need to slide a piece of rubber pad under your pool pump and tighten it together with the bolts using an adjustable wrench. The rubber pad will help cut down the noise by acting as a shock absorber to the vibrations.

Cleanup the Skimmer Baskets

Normally the skimmer baskets are found at the sides of the swimming pool. dysfunction is to collect and stop debris from going into the pool. A blockage of the baskets by the debris will prevent water from reaching the pump, hence creating problems like cavitation which will lead to loud noise.

Look out for the skimmer baskets and remove any debris or other objects that have accumulated in them. This will help bring back water flow to the pool pump and reduce the noise.

Cleanup Your Pool Pump Basket 

Cleaning the pool pump is as important as cleaning the skimmer baskets. The pool pump basket is another debris basket you need to clean regularly. To clean up your pool pump debris basket you need to switch off and disconnect the pump, this will prevent accidents such as electric shocks. 

Then close the valve that extends from the pool to the pump and remove the top pump cap. Once you remove the top pump cap you can easily take out the pool pump basket. But in some cases, you might not be able to take out the basket physically so you will have to remove the debris with your hand 

Removing the debris from the pull pump basket will help make the pump work effectively and become less noisy. 

Setup Vibration Pad to Reduce the Noise 

Even though you may not be able to stop your pool pump from operating and making noise entirely when you realize the vibrations are causing the loud noise, then you can remedy this issue by setting up an anti-vibration pad underneath the pool pump to help deaden most of the noise.

The pads are made of thick rubbers that can take in vibrations from the pump and prevent them from transferring into the pool base which otherwise may intensify the vibrations. Setting up an anti-vibration pad is simple. 

Just unbolt the pool pump motor and lift it from the surface it is attached to. After you have lifted it, slide the anti-vibration pads into position beneath the motor and lay the motor on top of it. Install and tighten all bolts around the pool pump motor. This will significantly cut down the vibration noise.

Clean the Impeller 

Inside the pool pump, there is an impeller fan that spins to push the water through the system. If debris such as leaves, twigs, insects, and other junk can get into the pool pump basket and cause the impeller to clog. When this happens the pool pump will not get enough water to supply the system hence causing it to work harder and become noisy in the process.

To solve this problem, you need to check out the impeller for clogs and also check the pump basket for debris. Remove the strainer from the basket and connect a garden hose to it and turn on the sprout. Fill up the basket with water and see how long it takes for the water to disappear. If the water takes time to disappear then it means that the impeller is clogged.

If you realize this, then you need to clean the impeller. To access the impeller you will have to disconnect the power supply to the pool pump, also unplug the pump from the plumbing system and unscrew the motor cover.

Once you have removed the motor cover you will see the quantity of debris that has built up in the pump. Clean all the debris from the impeller using a coat hanger. Examine the impeller for any damages and assembly of the pump.

Plug back the plumbing system and tune on the pump to find out whether the noise has stopped. The pump should run normally with less noise if the dirty impeller was the cause of the noise. 

Replace Worn-Out Bearings 

Inside the pool pump are two bearings that facilitate the smooth running of the rotors. Over time the bearings can lose their lubrication and begin to wear out hence causing the noise.

The pool pump bearings can be easily gotten at a shop at a cheaper price. Even though you can easily purchase the bearings, replacing them is labor-intensive. Replacing the bearings all by yourself can be extremely hard especially if your pump is old. Trying to open the pump can result in cracks.

Using the incorrect bearings or not positioning them properly can cause reversible damage to your pool pump. You also need to get specialized tools to get the jobs.

Considering all these it is better to get a professional to replace it for you at a cost. Because trying to do it by yourself may cause more harm than good.

Increase the Water Level in Your Pool

Another reason why your pump might make loud noise is low water levels in the swimming pool. There are always two lines in the pool.MAX and MIN, if the water level is at max no problem but if the water level goes below the MIN then the pump will make a noise. This is due to the pump not getting enough water from the skimmer. 

To raise the water level you need to attach a garden hose to the water trap and allow the hose to run into the pool. Switch on the spout and allow the water to run until it rises above the skimmer openings.

When the water level is high it slows up the movement of water into skimmer openings. This slow movement of the water prevents debris and foreign materials from being pulled into the openings. Also, one good thing about the high water level is that it makes foreign materials and debris float above the skimmer openings and thus reducing the chances of opening clogging. 

Level Off the Pool Pump and Filter 

When your pump is not fixed properly it can cause the generator to vibrate and cause excessive noise. To mitigate this problem you need to check out if your pump is properly fixed. If it is not, then unbolt it from its current position and set it up to level.

You can call a professional to set it up correctly for o if you think you can’t reinstall it properly. 

Use a Cartridge Filter 

If you use an old sand-filled pool filter you will realize that it has ports where water passes before reaching the filter which causes loud noise within the pool pump. 

You can easily remedy this problem by replacing your old sand-filled pool filter with a cartridge filter which is quieter and doesn’t need a port to function. It is also easy to fix as you don’t need to fill any sand like the old filter style. 

Set Up a Pool Pump Cover 

This is one of the simple ways to quiet the pool pump. All you need to do is place a pool pump cover over it.  The cover will deaden the noise from your pool pump and absorb it from dispersing to you and your neighbors. 

The cover protects your pool pump from elements of the weather and provides enough ventilation for your pool pump to function effectively. 

Replace Broken Seals

One of the reasons why your pool pump may make loud noises is a broken seal. The seals can crack due to high temperatures within the pump or being in operation for hours without water. Check if the seals are and get a professional to replace them for you.

Create a Soundproof Enclosure for Your Pool Pump

One way to cut down the noise from the pool pump is to cover it with a soundproof box. You can build a soundproof box using plywood to create frames and coat the inside wall with green glue to enhance the absorption of noise. Ensure to create enough holes for ventilation when building the box.

Purchase a New Quieter Pool Pump 

Sometimes the most effective way to get rid of a problem is to start all over again, by purchasing a quieter model you will have less noise. If your pump is the old type model you will notice that it hasn’t been very quiet. But in recent times the improvement in technologies has made some of the pool pumps quieter.


If you’re fed up with hearing the loud noise from your pool pump that keeps disturbing your peace and testing your patience then you are not alone. We have provided the best methods to help you quiet your pool pump. Read the article above clearly and choose the suitable method to remedy your problem. 

You should also maintain a regular cleaning routine and remove debris from the baskets to reduce the noise and also prevent huge repair costs in the future.
