How To Make Your Sink More Quiet

Kitchen Sink Noise

The plumbing in your home is often the number one source of strange noises that plague your family, especially kitchen sink noise. Whether it's eerie creaks or unexpected thuds that keeps you and your family up at night, the reason these irritating disturbances occur is typically a result of poor insulation or lazy installation. A noisy kitchen sink is one of the worst household plumbing offenders, but also the easiest to fix. Paying special attention this vital household feature is key to preventing kitchen sink plumbing problems.

The kitchen sink noise can turn a everyday task like cleaning dishes or washing your hands into a unwanted, disharmonious symphony. Dropping a fork in the sink shouldn’t make a jarring noise or leave you with a headache. Read on for an easy way to make your sink more quiet.


What causes kitchen sink noise?

Do you hear that deafening clamor when water pours out of the faucet? This is most common in sinks that feature two basins and are part of one singular unit. If these two basins are each made out of metal, such as stainless steel, you are more likely to notice the "gong-effect,” resulting in kitchen sink noise. Metal sinks amplify sound waves, whereas stone and porcelain sinks are more dense and will absorb noise.

If you have a two-basin sink, there is usually a hollow expanse on the underside of the sink that separates the two. This empty space acts as an echo chamber and causes your sink to sound like a steel drum when you turn the faucet on.


Making Your Sink More Quiet

The most effective way to make yourdual-basin kitchen sink more quietis to fill the hollow space between the basins with expanding foam. The foam lessens the gong effect by deadening sound vibrations. It's possible to do this with your sink in place, but the job will be easier and more precise if you remove the sink to apply the expanding foam. Don’t worry! We’ll walk you through the steps of how to fix a noisy sink.


How To Fix A Noisy Sink 

1. Remove the sink basin.

  • Although you can approach applying insulation from beneath the sink, it's best to remove the basins before starting the project.
    • Empty out all items from underneath your sink.
    • Put on protective eyewear, mask and gloves.
    • Unplug your garbage disposal and turn off the circuit breaker that runs to that area. One of the most important electrical safety tips is to always keep electronics away from water.
    • Turn off the water supply to the sink. Make sure you know how to locate your home’s main water shutoff valve, as a precaution.
    • Disconnect the water supply lines from the underside of the faucet.
    • Disconnect the drain pipe from the sink and garbage disposal.
    • Remove your garbage disposal.
    • Cut through the caulk along the edge of your sink, detach the sink from your counters and carefully pull the sink out.

2. Fill hollow space with basic expanding foam.

  • Purchase basic expanding foam from a hardware store.
  • Fill in the empty gap between the two sink basins with the solution.
    • By putting insulation into this dead space, you remove the echo chamber and will make the kitchen a much more peaceful place.
    • Be sure not to apply too much of the foam, as it will expand and potentially make it difficult to refit your basins.
    • Let the foam set for at least one hour before moving the sink.
  • Optional: An alternative method to soundproofing your sink involves attaching pieces of mass-loaded vinyl insulation using adhesive to the underside of the sink basin.

3. Place the sink basin back and caulk the edges of your sink.

  • Once you have put the sink back into the countertop, be sure to properly caulk all of the edges.
  • Wipe away any excess caulk.

4. Reinstall your sink.

  • Refit any plumbing or electric units you had to disconnect before utilizing your quieter kitchen.
