Why is your pool pump so noisy?                                                                                                                                                                                                                                                           

There are several reasons that could make your pool pump noisy. The following 4 situations are usual to most of the noisy pool pumps. Let’s find out if your noisy pool pump fits any of them here:

  • Poor Installation on the Pool Pump Base

Poor installation of your pool pump on the base could lead to chattering on the concrete and cause the vibration noise. Loud pool pumps installed on wood decks are always noisy, since wood decks act like a drum and resonating the vibration and motor noise.

To test if vibration is causing your pool pump noise, press down on the pool pump and motor to see if the sound changes.

  • Pool Pump Cavitation

Unmatching size of pipe and pool pump could cause cavitation noise. If the pool pump is too large for the pipe size to get enough water for operation, it will produce low, gravely sounds, which can be very loud.

To test if there’s pool pump cavitation, you can disconnect the motor from the pump, and turn on the power briefly to listen to the motor.

  • Full Pump Basket or Clogged Impeller

Too much debris like leaves, twigs, insects and other trash in the pool pump basket could easily clog the pool pump impeller or skimmer, causing the lack of enough water and forcing the pool pump to work harder and becoming noisier with a loud grinding noise.

Any reasons that prevent the pool pump from getting enough water could cause cavitation noise, such as low swimming pool water levels.

  • Worn Bearings

The two main shaft bearings inside your pool pump’s motor, the front bearing and the rear bearing, are key elements to keep the rotor turning smoothly. With the lubricants inside the sealed bearings growing thin over time and causing bearings to wear out, screeching and grinding noise will become so loud that can’t be ignored.

To test if the motor bearings are the problem, you can pull the motor out of the pump and turn on power briefly to listen to the sound.

Solutions to Quiet the Pool Pump

Now with the possible reasons that usually cause your noisy pool pump, let’s figure out how to quiet your lousy pool pump. Here are 5 useful ways to quiet pool pumps:

1. Secure your pool pump on the base.

Your pool pump is supposed to be bolted down to the concrete pad, which can secure the pool pump from movement or vibration. If your pump has already bolted, check if the bolts are tightened, as they can loosen up from the constant vibration of daily running over time.
If it doesn’t work for your pump, you can also put an anti-vibration pad beneath the pump, or slip a square of rubber or a carpet remnant under your pump base to dampen the vibration.

2. Raise the water level in your pool.

Apart from the vibration noise, the cavitation noise is also common. If your pool water level isn’t high enough to reach the openings on the skimming baskets, it may be too low for enough water to get into the filtering system and supply your pool pump. If so, you can easily solve this by adding more water in your swimming pool.

3. Empty the skimmer and pool pump basket.

Too much debris in the baskets of your skimmer and pool pump will reduce the water flow to reach your pool pump and cause cavitation noise as well. Empty each of the skimmer baskets and the basket inside your pool pump now. And don’t forget to clean them out regularly to avoid clogging issues or irreversible damage to your pool pump.

4. Replace the worn-out bearings.

Worn bearings are always the inducement for loud pump motors as they affect the rotor from turning smoothly. Though the bearings are not very expensive, they are difficult to be replaced. You may need to hire the professionals to change them out.
If the pool pump motor keeps squealing and screeching, it could be necessary to replace the motor and shaft seal or replace the pool pump.

5. Replace pool pump with quieter model.
