Editor’s Recommendation: Top 5 Garbage & Waste Disposals Units

Things to Know Before Purchasing a Best Waste Disposal

When installing a garbage disposal in your home you should have several aspects in mind. We explain them to you:

Continuous-Feed Disposal

A continuous-feed disposal is exactly what it sounds like. After flipping a switch to turn the disposal on, food can continuously be added. The food is grinded into small enough pieces to fit in through the holes between the disposal unit and the bottom plate. Once they’re small enough to fit through, the food is flushed down with running water.

Batch-Feed Disposal

Using a batch-feed disposal is actually quite simple. After putting food into the drain, you seal the drain with the stopper that should have came with the disposal. As soon as you turn the stopper, the disposal is activated and then works the same way the continuous-feed disposal works.

Septic Tank Specific Disposal

If you have a home with a septic system, you’re required to have a specific type of garbage disposal. This type of disposal works the same way that a continuous-feed disposal works, but this disposal also has a special cartridge that is used to break down the grease and soap that can build up in the system. Also, a microorganism is added to help break down food waste.

So now that you know the types of garbage disposals there are, you have to decide what you’re looking for in a garbage disposal. Here are a few things to consider:

Motor Size

The size of the motor is the most important part to think about when purchasing garbage disposal. The motor size of garbage disposal is rated in horsepower. The higher the horsepower you have, the more powerful your disposal will be. If you are a little rough at your disposal, you’ll want one with a higher horsepower.

Grinding Chamber

The grinding chamber is where all the hard work happens. If you have a garbage disposal with a smaller motor, your grinding chamber will be smaller, as well. Some garbage disposals have stainless steel grinding chambers, which they claim to stay cleaner, but stainless steel tends to break, so make sure you do your research before dishing out the money for stainless steel.


Let’s be honest; nobody likes the sound of a garbage disposal. There are some disposals that come with sound-proofing technology to eliminate the harsh grinding sound. If you want a quieter disposal, you might want to get one with a larger motor. Once again, just make sure you do your research.

Buying Guide of Waste Disposal

Grinding and deposit function

The key to a good garbage disposal is in your grinding system, since this is what establishes both the waste treatment capacity and other parameters of interest such as the type of food that can be treated and the corresponding noise level.

See Also: Best Under Cabinet Range Hoods Reviews

To begin it is important to check that the power of the product is high, depending also on the capacity of the crushing tank, since this is the key to be able to crush all kinds of food. The greater the power the smaller the result of this crushing will be and the greater the capacity to be able to reduce drier and harder residues efficiently.

The capacity of the deposit is another important issue when buying the product. The grinding deposit has a specific capacity that establishes for how many users the product is recommended. As a sample, a team with a capacity of one liter is suitable for 3 people, while those of 4 people offer capacities from approximately 1.2 liters. Keep it in mind when buying.

Within this grinding function we can not forget to talk about the generated noise. Fortunately, current models have greatly reduced the level of loudness in operation, so today’s product is much quieter. However, it is something that should be evaluated to avoid that each session of crushed remains implies having to put some ear plugs.

Manufacturing materials

Since this product deals with water and garbage, check that the materials with which the equipment is manufactured are adapted to this type of use. In particular the most common materials in the manufacture of these appliances are the stainless steel for the interior and the grinding device and the PVC for the plastic elements.

In any case it is very important that the grinding devices, both the tank and the crusher itself, are made of quality metallic materials. We think that these materials are going to be subjected to high tensions, to a continuous contact with humidity and to be used against remains, sometimes of high hardness, which causes them to be damaged if they are not suitable.

Something similar happens with the necessary plumbing connections, both to hold the crusher and to connect it to the water outlet. Nowadays PVC is the most modern, light and resistant product with which connections and plumbing works can be made, also offering a flexible design that absorbs the vibrations of the product. Any other material could deteriorate or loosen if it is not of sufficient quality for this work.

Installation of the product

One of the keys to be able to have an efficient shredder is the installation of the equipment. In principle, this installation is as simple as placing it under the sink, connecting it to the electrical network and to the drain of the kitchen and start grinding. However, it is convenient to see some previous elements that guarantee an easy installation.

On the one hand it is necessary to see that the connection measures correspond with those of the sink, so that we do not have to use additional elements. Also check that the connection elements are preferably PVC and fit properly, to avoid water and dirt leaks when installing it.

On the electric side, the most recommended models are those that include a conventional plug, as they are safer and save us having to go looking for splice to connect to the power. Check that the plug is European type, because if it is English type you will have to add an adapter to your shopping list.

Finally we can not forget the space available, so that the larger the garbage disposer chosen, the smaller the space available in the lower part of the sink will be. Keep it in mind not only because you have enough space for it, but above all to avoid running out of space under the sink if the product is too large

Now, let’s take a look at why you should put a garbage disposal in your home.

● They’re Affordable

It can cost quite a large amount of money to have a plumber come out and unclog your drains for you. Waste that accidentally gets shoved down the drain can become a huge problem. Having a best dust collector greatly reduces the need to have to spend money on a plumber.

● They’re Easy to Clean

All you have to do is rinse off the motor and it is clean. You can even do this if your garbage disposal gets clogged!

●They Get Rid of Bad Smells

When you have food sitting in your pipes they begin to emit a horrible odor after some time passes. The food is literally rotting in your pipes. Having a garbage disposal completely eliminates this from happening. Waste is grinded up into small pieces and immediately brought down the drain. It doesn’t have time to linger and start stinking up your house.

● They’re Good for the Environment

Most of the waste sitting in landfills is food waste. Having a garbage disposal allows you to get rid of the waste in a more environmentally friendly manner. Garbage disposals also make people stop using plastic bags to throw away waste, which is absolutely fantastic for the environment.

Advantages of a garbage disposal for your home

There are many advantages that can bring you a garbage disposal for your home, for your kitchen, for your restaurant … below we detail some of them.

  • Cleaning. With a garbage disposal you can turn the food waste into liquid to pour down the sink drain. Therefore, one of the main advantages of using a garbage disposer is that the waste in the bin is considerably reduced.
  • Healthiness Garbage cans with organic waste such as food waste are one of the main sources of batteries and insects. With the garbage disposal you will dump the waste through the sink and you will have a more hygienic and ecological home.
  • Comfort. Are those daily trips to the dumpster heavy? According to manufacturers, up to 60% of the garbage that accumulates each day in the home comes from organic waste and food waste. Thanks to a garbage disposal you will reduce considerably the amount of garbage generated in your home and you will avoid a trip to the container.

Follow these simple directions and you’ll have a brand new garbage disposal to use in absolutely no time.

  • First, make sure the circuit breaker in your kitchen is turned off. Put a bucket underneath the P-trap and disconnect your drain pipes. The sink strainer needs to come out next and any excess putty needs to be removed.
  • You need to put putty along the flange of the new drain and press it into place. Put a towel in the sink and put the disposal on the flange to make sure it doesn’t move.
  • Under your sink stack the fiber gasket, backup flange, and mounting ring and slide them underneath the flange. Pull open the snap ring and snap it into place. Tighten all the screws and remove any excess putty.
  • Use a hammer to knock out the dishwasher drain and remove the plug from the inlet on the disposal.
  • Remove the wire cover and connect all of the wires according to color. Push the wires back in and put the plate back on.

There you have it! That wasn’t hard, was it? Now you have a perfect garbage disposal to eliminate all of the food waste in your home!

Hopefully, after reading this, you decided to install a garbage disposal in your own home. Not only will you be helping the environment by eliminating the amount of waste that you put into the landfill, but you’ll also put more money in your pocket by reducing the risk of clogging up your drains by accidentally putting food down your pipes.

Just remember what to look for when you purchase your garbage disposal, and how to install it, and you’ll be on your way to a new way of getting rid of your food waste!

Garbage Disposal Frequently Asked Questions


1) Do I Really Need A Garbage Disposal Unit? Does a Garbage Disposal Add Value to a Home?

The answer to this question would probably be a ‘yes’.

Since anywhere between 10 to 20% of every household’s waste is actually food scraps, a question raises – What to do with it? The thing is, with other pieces of trash such as plastic bags, packaging, paper, cardboard, or glass there’s no problem when it comes to their disposal. That is – these can be disposed of in trash cans and transported to landfills.

With food waste, however, the story is quite different. Landfills with food scraps in them tend to produce a lot of methane due to the decomposing of organic fruits, vegetables, meat, etc. This can create a health hazard if not treated correctly.

Therefore, having a garbage disposal unit under your sink can help reduce overall waste of potentially harmful scrap food items. (They are ground and burned inside garbage disposal units.) This is not only good for your household hygiene but also helps the environment!

2) How Many Years Does a Garbage Disposal Last?

When compared with other electric appliances in your kitchen, garbage disposal units fare quite well when it comes to their longevity. Thanks to their durable builds and simple way of operation, these contraptions can last anywhere from 8 to 15 years before you need to replace them.

Usually, the thing that breaks down the first would be the blades, due to the amount of work they do over time. That said, if you have an older version of the garbage disposal and the only problem are the blades, you can simply replace them and continue using the device itself for years to come.

3) When Should a Garbage Disposal Be Replaced?

As is the case with virtually any contraption with a motor and a set of blades, a replacement should come when you start seeing the symptoms of wear ‘n’ tear. As we said above, the blades are the ones that go first, so if your garbage disposal unit is acting up – you should always check them blades.

On the other hand, if you see a poorer performance, that the motor has weakened, or that it gets clogged all the time no matter how much you fix it – it may also mean it’s time for a new disposal unit.

4) Do You Need to Empty a Garbage Disposal?

Garbage disposal units don’t need to be emptied. In fact, their sole purpose is to destroy food scraps and send them into drainpipes, so that you don’t have to do it yourself!

That said, garbage disposals can get clogged from time to time. Whether it’s because you threw in a large bone into it, or a piece of celery got stuck under the blades, these tiny annoying accidents can happen and the results are usually some rotten food and a bit of stench coming out of the drain. (Otherwise, there’s usually no danger of a more serious breakdown due to a simple clogging.)

Anyway, if your garbage disposal does get clogged, you’ll have to turn it off, remove the clogging culprit, clean up the mess, and then turn it back up again! (To see some tips on how to do this, see entry number 8 on this list.)

5) Can You Live Without a Garbage Disposal?

No, if you don’t have a garbage disposal unit under your sink, you’ll turn into a mini Godzilla and start eating birds and dogs in your neighborhood!

Jokes aside, it’s perfectly possible to lead a normal and hygienic life without a garbage disposal unit. Of course, having one of these machines under your sink will make your life easier when it comes to dealing with food waste, but if you’re willing to do it yourself – you can do without a garbage disposal just fine.

6) Can You Lubricate a Garbage Disposal?

There’s no need to lubricate a garbage disposal unit. Since most food that they grind and destroy is made of 70% water, the device will have more than enough liquid to work with to accomplish its tasks, so to speak.

In fact, pouring oil or grease in your garbage disposal will only make matters worse, because the grease will slowly accumulate around the blades and slow them down. Fat and grease can also clog the drainpipes.

7) Do You Have to Clean Out A Garbage Disposal?

Only if it gets clogged, or if you haven’t checked it for a while, otherwise – no. To be fair, as long as it works fine and there aren’t any strange noises coming out of the motor, even if you don’t clean it, it will run fine.

(More details about the cleaning process in case of a clogging below.)

8) How Do I Keep My Garbage Disposal Clean?

Alright, this is in case your garbage disposal gets clogged or you haven’t cleaned it for some time. Here are some steps you can undertake to get this done:

  • Turn off the power – … and remove large trouble-making chunks of food. Large bones, vegetable mush, and similar unprocessed food items.
  • Use ice and salt – A good trick to quickly disinfect and clean a dirty garbage disposal is to simply throw in some ice and salt into it and turn it on. It will do its cleaning magic to clean itself!
  • Scrub with a brush – In case your garbage disposal is heavily clogged, you might need to use an old toothbrush or a similar tool to clean the blades and its surroundings.
  • Baking soda and vinegar – A century-old cure for all sorts of dirty messes. First, pour some of the mixtures into the drain, let it sit for some 10 minutes, and then rinse it with hot water! (The garbage disposal needs to be running while you rinse.)
  • Rinse with bleach – Mix in a tablespoon of bleach with roughly a gallon of water, pour it into the drain, wait for a couple of minutes, rinse with hot water while the unit is running, Bob’s your uncle!

9) How to Install a Garbage Disposal?

Here’s a brief explanation of how to install a garbage disposal unit. (Mind you, these are just the basic steps. You might also want to consult a professional guide, in case you’re not experienced with this sort of work.)

  • Turn off the circuit breaker – … and prepare a bucket to place underneath the drain. (Expect some water to drip from above.)
  • Apply plumber’s putty – Take the new drain you’ve received with the disposal unit, apply the putty around its flange, and press it tightly into place. Make sure it doesn’t move.
  • Get the garbage disposal ready – … by knocking out the drain plug from the disposal inlet. After this, you’ll be able to connect the unit with your sink.
  • Connect the wires – Remove the protective plate and match the wires according to their color. Once you’re done, put them back in place and screw the cover back on, as well.
  • Connect the disposal unit with the drain – Place the disposal unit underneath the flange you’ve prepared earlier, align them so they fit together, and secure everything in place with bolts, et voila! – you’re garbage disposal unit is ready!

10) How Does a Garbage Disposal Work?

A garbage disposal uses a motor to power a set of sharp blades that spin fast in order to destroy whatever comes into contact with them and turn it into a fine pulp. This watery pulp is then sent down the drain along with wastewater into the sewage system. Simple as that!

(An important note: Never, under any circumstances, should you reach with your hand into the drain while the garbage disposal is working! You can easily lose some fingers this way.)
