Why you should use an ultra quiet garbage disposal

There are many reasons why you should use an ultra-quiet garbage disposal. 

  • Quiet disposals process garbage in short bursts so they do not consume as much electricity as other units saving you a huge amount of money on your energy bill.

They also cut up waste into smaller bits which makes it easier for grinding.

  • Using loud garbage disposal at night can disrupt activities and have an effect on the sleeping habits of both the young and old. 

The sound can trigger severe psychological and bodily conditions that may have long-term effects. 

  • If there’s anyone at home suffering from anxiety, PTSD or terrible migraines then you need a soundproof garbage disposal system. 

It is best to soundproof your entire home as much as possible since noise beyond a certain level can intensify these conditions and make things worse.

How quiet can the most quiet garbage disposal get?

Surprisingly, well-insulated garbage disposals produce sounds ranging from 25 to 45 decibels.

This is lower than the sounds produced when two people are having a normal conversation which is at 60 decibels.. 

The noise produced by the garbage disposal mostly depends on the level of insulation that it has. 

You will find that the premium products will have better insulation than the cheaper ones. 

However, you may find a few budget-friendly choices that do have good insulation. 

 Keep in mind that the sounds coming from your disposer is not just from the motor running and grinding but it can also come from the vibrations it causes on the sink. 

That is why it is important to purchase garbage disposals that fit best with your sink to minimize the risk of vibrations which can increase the level of noise.

Things to look for when buying the quietest garbage disposals

quiet disposal food scraps

When searching for the quietest garbage disposal there are some important factors to keep in mind. 

We’ve outlined some of the most important factors to consider to ensure that you get the quietest garbage disposal that meets your demands. 

The motor capacity 

The first thing to look for is the motor capacity as the performance of any garbage disposal heavily depends on the power supplied by the motor. 

This means that the more rotations per minute(RPM)  the motor has, the more powerful it is. 

You should also take into consideration the frequency of dining and the type of waste you will be disposing of with the garbage disposal 

For example, if you are going to be disposing of hard kitchen scraps, it is recommended to go for a higher horsepower that can grind them into extra small pieces.

This will help to prevent clogged drains which can be quite a headache., 

On the other hand, if the waste is soft, you can opt for a unit with less horsepower since soft waste can be easily crushed. 

The size of your family can also help to determine the horsepower of the motor.

Small families should go for a ½ HP motor and medium-sized families can go for a ¾ HP motor.

Type of feed 

Garbage disposals come in two feed types and can be either a continuous feed type or a batch feed type.

Continuous feed garbage disposals get to work after you press the switch and will not stop until you stop them. 

Batch feed garbage disposals will require you to put the drain stopper in place before you can switch them on. 

If you want something easy and convenient to operate then the continuous feed is your best bet. 

However, if safety is your number one concern then you should get a batch feed garbage disposal. 

Performance 

if you’re buying a garbage disposal, you want to perform well and not leave you halfway through the process.

Good garbage disposal will be able to shred and grind your waste properly. 

Try to get garbage disposals that have a multi-stage grinding process because they pre-cut the waste into smaller pieces before crushing. 

This type of garbage disposal also helps you to use less energy since they do not require as much power to run as other units. 

Another advantage of multi-stage disposal is that due to the cutting and crushing of waste, you experience fewer clogs than other models. 

Noise levels 

It is important to remember that all machines will produce some level of sounds no matter how quiet it is marketed as. 

Even the most quiet garbage disposal will make some noise.

However, you’ll find garbage disposal systems that are designed with a sound-absorbing mechanism tend to produce low noise levels when in operation. 

Larger garbage disposals will include a sound seal or sound shield mechanism which helps mask the noise produced. 

These mechanisms are designed in such a way that they cage the motor in several layers of some deadening materials so that less noise can escape. 

On the other hand, smaller models have weak motors with a low RPM and may not require some masking mechanisms. 

This is because these motors aren’t that loud, to begin with. 

Other features

Pay attention to the power cords, switches and connections for your garbage disposal.

Be sure to get the right setup so that your disposal can function correctly.

Ideally, you want your garbage disposal to come with a sink flange.

The sink flange connects the disposal to the sink and prevents waste from spewing back out of the hole.

Another important thing to consider is the type of switch you want.

You can choose a flip switch or an air switch.

Flip switches are placed close to the wall mount to facilitate Continuous-Feed disposals.

Meanwhile, air switches are placed on the countertop.

Air switches are much safer because they keep the electric circuitry away from the sink’s water supply thereby reducing the risks of electric shocks.

Last but not least, check to make sure that your unit comes with a power cord.

If not, buying a lengthy power cord may be handy in the event you do need extra length at some point in the future.

How to make your garbage disposal quieter

If you already have a garbage disposal and are looking for ways to make it quieter, then this section is for you.

Sometimes even if you buy quiet garbage disposal, you may find that it is still a bit too loud for you.

This may or may not be because of false advertising by the manufacturer or a faulty product.

Other times, it could be louder than advertised due to problems with its installation as we’ve mentioned before.

If you’re not certain on how to install your disposal, call in the professionals.

In addition to this, here are a few other things to try.

Use spray-on coating on stainless steel sink

spray on coating quietest garbage disposals

When in operation, garbage disposals vibrate and those vibrations can get amplified and multiplied by the surface of a stainless steel sink.

Sinks made from porcelain cast iron tend to be better at absorbing noise.

Some sinks come with a coating that dampens sound and makes the metal less noisy.

However, if you have a stainless steel sink and no coating, you can add your own.

Spray your sink with a stainless steel sink with a spray-on coating which will help to reduce the level of noise coming from the garbage disposal attached to the sink.

Soundproof the upper half of the garbage disposal

You can opt to soundproof the upper half of your unit using sound insulation and sound-dampening materials.

Covering the motor and grinding chamber significantly reduces the number of sounds coming from the disposal.

However, this may be hard for you to do but you can cover the body of the disposal with these soundproof materials.

This will reduce the amount of noise you hear.

Don’t worry too much about the aesthetics as anyone hardly sees the garbage disposal in the kitchen.

Use flexible hoses

Swap out any hose hooked up to your garbage disposal that is not flexible. 

Flexible piping connections will reduce vibrations which in turn create less noise when your disposal is in operation. 

This may not be practical in some situations but if you can, do it asap and be amazed at the difference. 

Buy a new garbage disposal

If you’ve had your unit for years and no matter what you do, it still isn’t quite enough, it’s time to buy a new one.

If you want a unit that makes the least amount of noise, then choose a batch feed unit.

These disposals come with a cover so they will prevent noise from escaping through the inlet.
