How To Troubleshoot Noisy Pool Pumps

Some pool pumps are naturally noisy while others, which are manufactured by companies that highly concentrate in engineering and R&D produce quieter pumps. Such top pump manufacturing companies include the Pentair Intelli-Flo and Hayward EcoStar. Note that the installation of the pump and the number of elbows connected to the intake or outtake directly affect the flow of water. That in turn increases the amount of effort that the motor and the impeller require to do, consequently raising the noise level noticeably. One should also remember that every pump installation is unique. Similarly, all swimming pool designers are doing their best under the diverse environmental limitations they encounter in their work and design.

As we all know, pool pump motors circulate water from the swimming pool, to the filter and then back into the pool. That keeps your swimming pool clean, sanitized and free of debris. Most pool pumps emit the small noise when operating. However, under normal conditions, the noise level it emits should not be too loud to distract you or your neighbors. A distinct alteration in the noise produced by the noisy pool pump and an increase of noise signals a problem with the pump motor. You can remedy this by making some little repairs or some adjustments. If your pool pump is noisy, the following noise reduction steps will keep your home serene and probably give your neighbors some peace.

How to troubleshoot if the impeller is the source of the noise and not the motor?

Most pumps are self-primed

1. If you want to achieve noise reduction that is coming from the impeller, first turn off the loud pool pump motor and then disconnect the electrical powering. You may just require unplugging the noisy pool pump or needed to turn off the circuit breaker depending on how the motor is installed. To test successful power disconnection, attempt turning on the pump.

2. Remove the lid from the pump as you do when cleaning the strainer of a loud pool pump motor. Air will penetrate and the water level will lower about ¾ of the way.

3. Screw the lid back in place tightly per manufacturer specifications.

4. Turn power back-on. You will notice that the motor doesn’t make any noise until the water pressure rises and the basket is full again and the flow of water becomes constant. This noise is caused by cavitation.

Pump Cavitation

Most places where cavitation happen are in pumps, propellers or in flowing liquids. As an impeller’s blades flow through fluids, low-pressure areas are created as the fluids accelerate while moving past the blades. The faster the blade pace, the lower the amount of pressure that can be created around it. When it becomes vapor pressure, the fluid vaporizes and ultimately forms small gas bubbles. That is what is known as cavitation. When the bubbles collapse, they cause strong shock waves in the fluid that are audible and capable of even destroying the blades. Therefore, it is important to remedy the condition before it damages your pump.

How to Prevent Pool Pump Cavitation?

Cavitation cannot be rectified on pumps having enclosed impellers. The problem could be as a result of a clogged outlet filter. Regularly open the confined discharge valve inside the pump to check its state. Normally, troubles arise from clogged outlet filter, closed release valve or an over-pressurized header.

Bottom Line

All along, many swimming pool pump manufacturers have been manufacturing robust pumps that apparently apply the “quiet technology”. However, most of them have be proven less resilient thereby leaving many consumers dissatisfied and many neighbors unhappy where mediators or lawyers needed to be contracted. Our patented product, Serene+, offers the ultimate cost-friendly soundproofing solution. You can run to some pool pump dealers and spend hundreds of dollars, but you cannot get 75 percent to 90 percent noise reduction at our price. Serene+ is the premier noise reducer for existing on new pool pumps. The soundproofing covers are light and durable. Serene+ easily fits in commercial or residential pool pumps.

  1. You did a great job of explaining the troubleshooting steps to fix a noisy pool pump. Sometimes we are also experiencing this kind of noise and just leave it that way since we don’t know what to do. Thanks for this useful information and I guess, we’ll be asking a professional to check on this for safety purposes.
