Everyone, including your neighbors, hates noise. But during summer, all the neighborhood pools tend to become functional as many people want to keep themselves fresh.
Some people never offer maintenance and repairs for the pool pumps before switching them on after a long winter season. A well-maintained pool pump tends to produce humming sounds that are not audible.
However, a poorly maintained pool pump will start producing loud humming and screeching sounds that can be disgusting.
This noise can cause a rift between you and the neighbors, as many people prefer to relax in a calm and quiet environment, especially when the sun is hot in the afternoon.
Some neighbors will even wish the summer period to end, but this might not be a permanent solution since it will automatically come again.
The best thing to do is to listen to the sound and determine the reasons why the pool pump is so noisy. This will help you know where to start diagnosing the pump.
In this article, you will learn some of the common reasons behind the noise and how to quiet a noisy pool pump.
Why Is My Pool Pump So Noisy?
The pool pump is an essential part of the pool plumbing system. It plays a vital role in providing pressure so that the water flows through the filters.
Unfortunately, there are times the pump fails to work, and this is signified by the production of a loud humming sounds that are usually irritating. Here are the possible causes of the noise from the pool pump:
This problem arises when the pump is starved with water, or it is unable to get plenty of water at a fast rate. The pump impellers are known for spinning quite faster when the water is not enough.
So, it will start beating the air molecules found in the small amount of water passing through it. In the long run, the pump will suck in more air and later lose its prime functionality.
This will make the pump dry, and the small amount of water inside will boil and steam. The rising of the steam will make the shaft inside to fail, and this will also result in the total breakdown of the pump.
Therefore, the loud and disgusting sound will result since the impeller shafts get too hot and get separated from the brass.
Clogging of Internal
Parts A busy pool is prone to debris, and these are the major factors that result in the internal blockage of the pool pump.
The pump has the capability of pulling the debris that is close to or around to its housing. The clogging of the internal parts of the shoe will trigger the grinding noise, and for sure, this is quite irritating.
However, poorly design pool pumps can also trigger the grinding noise since the impellers tend to touch the face of the volute.
Anytime your pool pump starts making a loud noise; it is advisable to pay close attention to the debris and the impellers.
Worn Out Bearings
A pool pump has two bearings inside that help it to function well. These bearings help the rotor to turn smoothly. But due to the frequent use of the pool pump, the lubricant inside will become thin, and this will make the bearings to start making a loud noise.
Always pull the motor out of the pump to test if the bearings are the cause of this disgusting loud sounds.
Pool pumps are typically bolted down to the concrete pads to prevent theft cases and inhibit the pump movement. However, this does not stop the pump from vibrating on the concrete pad. Continuous functioning of the pool pump will trigger a chattering noise sound.
Water Leakage from the Pump
When the pump is leaking lots of water, it will result in the pressure side, which hurts the impellers. This will facilitate the suction effect, and the impellers will fail to perform their roles, causing the loud noise sound.
How Long Does A Pool Pump Last?
With frequent use, most pool pumps have a life expectancy of about eight to twelve years before needing replacement.
However, some factors affect the life expectancy of a motor, and if not careful consideration, they are likely to affect its functionality. Here are some of these factors:
Size of the Pump
If you own a small pool pump, it will struggle a lot to move water to the required place, and continuous overloading will affect its lifespan.
On the other hand, big pool pumps tend to take little time to fill the pool, and this helps to minimize the overload time hence a longer lifespan.
Usage of the Pump
The life expectancy of your pump depends on how you use it. If the pump is frequently used, then it is prone to experience some failures as compared to the one that is used once.
Frequent usage of the pump makes some parts worn out faster, and this could be the reason behind the loud noise.
How To Quiet A Noisy Pool Pump
A properly functioning pool pump tends to produce low sounds that can never bother your neighbors and yourself. So, if you have a loud noise production pool pump, here are ways on how to reduce noise production. They include:
Reduce Pool Pump Motor Vibration
Vibration should be the first thing to put into consideration when your pool pump is making lots of noise, but it is usually not that serious.
I recommend you check the base of the motor with the concrete pads and if the bolts are loose then find the way to bolt them tight.
Loose bolts make the motor to screech the concrete pads and result in vibration noise, which is usually very loud. Use an adjustable wrench to tighten the bolts.
If the locks do not fix the issue, then replace them with new once. However, you can place a wood pad instead of a concrete pad then try to tighten the bolts from the motor. This will help to get rid of the vibration sounds permanent.
Clean Out the Skimmer Basket
Skimmer baskets tend to be located along the sides of the pool, and they tend to collect lots of objects, either large or small.
Therefore, the pool pump will not be able to receive adequate water and start making loud noise due to the suction issue.
I recommend that you have the habit of cleaning the skimmer basket regularly to prevent excessive accumulation of objects like leaves.
Find a technique on how to remove objects that are stuck inside the skimmer basket with ease. This will help to reduce the suction issue hence promote proper functioning of the pump.
Increase Water Level in the Pool
Pool pump motor tends to struggle, especially if there is no enough water in the pool due to skimmer basket blockage.
The continuous pumping with inadequate water will make the pump to overheat, and this will result in the production of noisy sounds.
Therefore, ensure to clean the skimmer basket to allow an increase in water entry into the pool pump motor hence reduce noise production.
Clean the Pump Basket
A pool pump basket can easily be clogged with leaves and other debris which inhibit entry of water to the inside. This will cause irritating noise.
You will be required to unplug the pump motor and open the lid. Clean the basket thoroughly and fill the pump with water then insert the lib back.
Plug the pump on to allow the air out of the filter. Once all these have been achieved, the pump will experience a low sound production that is considered to be normal.
Clean Out the Pump Impellers
The pump motor impellers are prone to trapping vegetation and debris. Constant trapping will clog the impellers, and this will result in loud noise.
The clogging will reduce the flow of water in the pump motor hence result in screeching noise that can be irritating. I recommend you turn the pump off then use a hook to remove the leaves or the clogged debris from the impellers.
Replace the Worn-out Bearings of the Motor Pump
Regular use of the pump makes the bearings worn out, and this can result in that grinding noise. Also, the older the pump, the more the corrosion on the bearings and the bolts.
Therefore, if you have a pump that has bearing issues, it is advisable to replace them from the nearest repair shop. This will help reduce grinding sound production.
Replace the Entire Pool Pump
If you have an old worn-out pool pump motor, it will automatically produce the noisiest sound in the backyard. It is advisable to buy a new pool pump motor to replace the old one to prevent the production of the disgusting noise. Take time to do thorough research and pick the best pool pump motors that have excellent performance.
Final Thoughts about Noisy Pool Pump Reduction
If your pool pump starts to produce a loud noise when functioning, it is an indication that there is something wrong. It is advisable to identify the source of the noise and what is causing it before thinking about keeping the pump quiet.
The tips listed in the article will help you know the reason why your pump is making a lot of noise and some ways on how to quiet a noisy pool pump in your home.
