What To Look For In The Best Garbage Disposal?

Best Garbage Disposal

No matter which brand you’re a fan of, there are certain features that make a garbage disposal better for your particular needs. If you want to find the best garbage disposal for your household, you should take into account the following things.

  1. Size Matters

When it comes to choosing the best garbage disposal for your household, size really does matter. The size of a garbage disposal is closely related to its motor power. The motor power is proportional to its grinding capacity, so it’s safe to assume that a larger unit will also have a better grinding capacity. However, you shouldn’t assume that a larger unit will automatically be better for you than a smaller one. Here are some tips on how to choose the right sized unit.

  • 1/3 HP Garbage Disposals

    These are the smallest units, and they have the lowest grinding capacity. However, these units can be the right ones for you if you’re not used to cooking on a daily basis. Moreover, these units are perfect for smaller households that produce a lower amount of kitchen garbage. If there are only one or two people living in your home, this might be the perfect size for you

  • 1/2 HP Garbage Disposals

    These units are slightly larger than the previous ones, but you shouldn’t believe that the changes between the two are significant. This is still a small unit, by all accounts. Being small also means it doesn’t have a large motor, so the grinding capacity of a 1/2 HP unit is still somewhat limited. These models can be a great addition to small households, or for larger ones who don’t cook too often.

  • 3/4 HP Garbage Disposals

    Now, these units are very well balanced. They still refrain some of the compact design of the smaller models, but they also use a larger motor. The larger motor increases their grinding capacity, so they are capable of going through more garbage without risking jams or blocks. The 3/4 HP units are better suited for larger households or for people who are passionate about cooking and spend a lot of time in the kitchen.

  • 1 HP Garbage Disposals

    These are the largest garbage disposals, and they’re also the most effective. These units are capable of processing most of the garbage you produce in the kitchen, and some of them will even be capable of reducing bones or tough beans without any problems. These units are somewhat bulky, so they will take up more space. They are better suited for larger households, and you can even use them for a small business.


If you want to learn more about the various advantages and disadvantages of the different sizes of garbage disposal systems, you should check out this article.

  1. Batch Feed And Continuous Feed. What’s The Difference?

Garbage disposal systems have two operating modes or feed types. Each of them has advantages and disadvantages, and choosing the right one for your home will make a world of difference.

  • Batch Feed

    If you choose a batch feed garbage disposal, you will have to use a stopper every time you use the unit. You will have to insert the stopper in the disposer’s opening and turn on the unit. This gives you the advantage of pre-loading the unit before turning it on.

  • Continuous Feed

    If you choose a continuous feed unit, you will simply be able to turn it on without using a stopper. You will also have the advantage of throwing waste down the unit without pre-loading it.

If you want to find out more about the differences between batch feed and continuous feed units, check out our Batch feed VS Continuous Feed Disposals.” article.

  1. Single Stage vs Multi-stage Garbage Disposals. Which One’s Better?

You might be wondering how a single stage garbage disposal unit works differently from a multi-stage one. Of what the advantages and disadvantages of choosing one or the other might be. Well, in the following section we provide a brief explanation of how each system is different so you can make your own decision about which is better for your home.

  • Single Stage Garbage Disposals

    Single stage garbage disposals have a simpler operating mode. If doesn’t matter if you choose a batch feed or a continuous feed model, a single stage unit will function in the same way. Once the unit starts, it will try to grind through all of the garbage at once. This means that all the garbage you dispose of should have a similar consistency and structure, so the grinder can reduce them at the same time. This is why most of the smaller units have a single stage operating mode.

  • Multi-stage Garbage Disposals

    These units have a more complicated operating mode. Some of then have 2 or even 3 grinding stages. The first grinding stage is similar to the one used by single stage disposers, but it’s not as thorough. During this step, the garbage is reduced to a smaller size. The following step will further reduce the garbage in size. If the system uses a third grinding step, that one will turn the garbage into a liquid, making it easier for it to go down the drain without clogging or jamming it.

Using a multi-stage garbage disposal is better if you spend more time in the kitchen cooking. These systems are capable of going through more garbage than a single stage model, and they’re also capable of grinding tougher components.

  1. Budget

Whenever you’re looking for a new appliance, you should start by setting a budget limit. You shouldn’t be very strict with your budget, but you shouldn’t be very permissive either. Spending more on a garbage disposal doesn’t necessarily mean you’ll get the better one, it might only mean you’re buying the more popular brand. However, spending more money might mean that the disposer comes with additional features. These features can make a huge difference, so you should seek them out in a product.

Additional Features Of a Good Garbage Disposal

When you’re willing to spend more money on a garbage disposal, you might not get a more powerful unit. However, the difference in cost might be the additional features present on a specific model and absent in another. Here are the main additional features you can pay for in a garbage disposal.

  • Power Cord

    Having a power cord on your garbage disposal can be very helpful, especially if you’re planning on installing the unit yourself. Garbage disposals usually come without a power cord, so you have to hardwire then into your electrical circuit. Hardwiring an appliance can be difficult, so a power cord can save you the trouble. If your disposer comes with a power cord, you will be able to install it and plug it into a regular outlet. Not only will this feature save you time during the installation, it will also save you time when you have to change the unit with a new one.

  • Auto-Reverse

    This is an anti-jamming feature. When hard or sticky materials get between the blades of the grinder, they can get stuck and lead to jams. This feature will allow you to reverse the way the blades spin, hopefully dislodging the jamming matter in the process. Some models come with a manual auto-reverse mode when you will have to manually set the unit in reverse, while more expensive ones have an automatic mode.

  • Blade Oscillation

    This is another anti-jamming feature. Models that use this feature have an oscillation pattern when their blades rotate. This oscillation pattern lowers the chances for food to get stuck between the blades, so you’ll experience fewer jams.

  • Steel Grinding Chamber

    Choosing a garbage disposal unit that comes with a stainless steel chamber is very important. One of the advantages of having a stainless steel grinding chamber is that it’s easy to clean. This means you won’t have to deal with a smelly garbage disposal as you would when using one made out of plastic. Another advantage is that the chamber will also be more durable, so you will be able to use the disposal unit for a longer time.

  • Quick Install Features

    Choosing a garbage disposal that comes with a quick install feature is very important because you will be able to install it easier. Not only that, but a quick install feature will also help you replace a unit in the future, when it’s damaged or when you want to upgrade it to a more powerful unit.

  • Long Warranty Period

    Garbage disposal units are usually backed by good warranties. Having a long warranty period is an advantage because they usually offer an in-home service. This means that a trained professional will come to your home to repair the disposer if there are any problems with it. A longer warranty period also reveals a certain amount of trust the manufacturer has put behind that product. The longer the period, the more confident is the manufacturer that the product is more durable.

Why It’s Important To Find An Easy To Install Garbage Disposal?


garbage disposals reviewsWhen you’re buying a garbage disposal unit, you should think of your action as making an investment. You should always get the most out of your money’s worth. This is why it’s important to find an easy to install the unit. Paying a professional plumber half of what you’re spending on the disposer should not be necessary.

Now, you might be wondering what you should do if you’re not used to getting involved with DIY projects. Well, it’s quite simple actually, you only have to try.

Most waste disposal systems are very easy to install, as you can see from following our How to Install a Garbage Disposal in 10 Quick Steps.There are also a lot of installation video tutorials you can watch online, so that shouldn’t be a problem if you’re patient.

An easy to install unit will also come as a great help when you need to change it because it’s old or when you want to upgrade it. Most manufacturers that implement quick installation features on their models use the same system for multiple models, so you can install any of them on the same mounting assembly. This can prove to be a great advantage in the future.

Garbage Disposal Units Maintenance

Garbage disposal units are generally considered low-maintenance appliances. You don’t have to clean them too often, but you have to clean them regularly if you want them to smell fresh at all times. To find out more about how to clean your garbage disposal, check out our How to Clean a Garbage Disposal: Methods Step-By-Step! post.

Besides cleaning the disposer, there is not too much maintenance work to be done. You should also throw in some ice once in a while. Most people believe this will sharpen the disposer’s blades, but that’s not actually true. In fact, this action will remove some of the debris buildups from the blade’s edges, making them more effective.

To keep the unit running properly, you should also be aware of what you should and shouldn’t throw in a garbage disposal. We recommend you read the Do’s and Don’ts While Using A Disposal to make sure you don’t make any mistakes while using it.

How To Make Sure Having A Garbage Disposal Is A Good Idea?

You should first make sure you’re allowed to install a garbage disposal unit before you buy one. If might seem silly, but in some parts of the country, you won’t be allowed to own one. Here is what you should take into consideration before buying a garbage disposal unit.

  1. Does your community allow individual garbage disposal units?

If you’re connected to the municipal water system, and your sewage goes to the municipal sewer system, you will need to contact the local authorities before you buy a waste disposal unit. The community sewer provider should give you all the information you need about the local policies that apply to sewage systems.

Some communities require a special permit before you’re allowed to install a new disposal system, while others outright ban them. Multiple communities in California have banned individual garbage disposal systems due to the drought that affects the state.

If you plan on using a garbage disposal system, and you’re connected to a municipal sewage, make sure you read all the rules and regulations that might restrict your options before deciding on a model.


  1. Is Your Septic Tank Capable Of Handling The Waste? 

Garbage DisposalIf you believe your home is connected to a septic tank and you want to install a garbage disposal system, the municipality might require you to use an upgraded tank which is capable of holding the waste. To find out if that’s the case, you might have to collaborate with a local building inspector.

If you’re not sure if your home is connected to the municipality sewer system or a septic tank, you should follow these steps to find out.

Keep in mind that if your house is connected to a septic tank and you install a garbage disposal system, you will have to empty the septic tank more often than you did before.

  1. Is Your Plumbing Up To It?

If your plumbing currently has problems with clogs and backups, you should not install a garbage disposal system until you upgrade it. If you know your plumbing has a weak spot where clogs frequently occur, you should replace or fix it before you even think about installing a disposer.

The additional waste that goes into the plumbing after you install the disposal unit can lead to additional problems, and can even lead to more severe ones.

If you have problems with clogs and backups but you don’t know why they happen, you should contact a professional plumber to identify and fix them before installing a garbage disposal.

  1. Would A Garbage Disposal Be Good For You? 

This is another aspect you should think about. A garbage disposal system is not expensive, and you will probably be able to install it by yourself, so you won’t spend a lot of money on it. However, using a garbage disposal will increase your household’s water usage, and consequently, your water bill will rise. Is a garbage disposal really necessary for your household?

If you want to make an informed decision about how helpful garbage disposals can be, you should read the following section.

The Advantages Of Using A Garbage Disposal 

You might be wondering why using a garbage disposal would be good for you. I mean, garbage is garbage either if you throw if down the drain or in the trash bin. Right?

Well, not really. There are several differences between using a garbage disposal system and throwing away all your garbage in the bin.

  1. Garbage Disposals Make For A Cleaner Home

When you’re using a garbage disposal, you’re throwing most of the food leftovers down the drain. That might not seem like much, but actually, it makes a huge difference in the sanitary conditions. Just think about it. When you’re throwing garbage away, most of the times foodstuff is the first one to decompose. When food is decomposing, it attracts all sorts of pests, from insects to rodents and more.

As a matter of fact, when food decomposes, it welcomes all sort of bacteria and microorganisms. These bacteria and microorganisms can disseminate to the surrounding environment, contaminating it. The contamination can be especially dangerous to small children and the elderly.

This is why grinding up food and throwing it down the drain is better for maintaining a clean home.

  1. Garbage Disposals Are Green

OK, some people might argue that garbage disposals use both water and electricity, so there are not really green. Well, when you look at things from this perspective, they might not seem green, but they actually are.

It’s estimated that about 13% of the solid waste that gets sent to landfills in the US each year is made out of food scraps. This might not seem like a big percentage, but it actually means about 32 million tons of food waste. When it arrives at the landfill, this waste starts to decompose, a process that produces methane gasses. Methane gasses are up to 21 times more potent than regular carbon dioxide gasses, and they are better at trapping the heat in the Earth’s atmosphere.

So, by grinding the food waste and throwing it down the drain, you’re actually fighting global warming. Cool, right?

Since we’re talking about helping the environment, garbage disposals are actually capable of doing even more.

Consider the amount of garbage you throw weekly at the bin. Now consider the amount of garbage without all the food scraps in it. It’s smaller, right?

All the garbage you throw is taken to a landfill using a refuse vehicle. These vehicles consume fossil fuels, so they emit gasses that go into the atmosphere. If everyone would throw away less garbage, the number of refuse vehicles used by the municipality would be smaller. This would eventually save energy costs for cities, lowering their overall energy consumption.

Moreover, when the garbage reaches the landfills, it is eventually incinerated. This process produces additional emissions that end up in the atmosphere. Less garbage means fewer emissions.

Last but not least, when you throw garbage away in the bin, you use plastic bags to carry it. These bags eventually reach the landfill where they stay for a long time before they are decomposed.

  1. Garbage Disposals Produce Waste That Can Be Transformed In Energy 

How can the food you throw down your drain transform into energy? Well, it’s actually easier and more likely than you believe.

When you’re connected to the municipal sewage system and you use a garbage disposal, the small food fragments that you throw away will eventually reach the municipal water treatment facility.

Most of the modern water treatment facilities don’t dispose of the waste they separate from the water to a landfill. Actually, they use it to create energy. They capture the methane gas created during the treatment process, and they use that methane to generate power or electrical energy.

  1. Garbage Disposals Transform Food Scraps Into Fertilizers

You might wonder how a small garbage disposal unit can transform food into fertilizer. Well, we have, to be honest, it doesn’t do it on its own. But it is the first of many steps that lead to this transformation.

When you use a garbage disposal system, you throw scraps of food down the drain. These scraps can reach a water treatment facility plant that is capable of selecting the biosolids in the water. Biosolids, also known as treated sludge, are the byproducts of the water treatment process. When the water is filtered, the solids are selected and treated, and eventually transformed into fertilizer. The resulting fertilizer is often sold to individual farmers, generating income for the municipality.

Biosolids are a better fertilizer than the chemical ones because they are more environmentally friendly, and they also have a good nutritional value for the soil.

  1. Garbage Disposals Don’t Use A Lot Of Water

This is a frequent argument for those who claim that garbage disposals are not green because they use water. They do, they can’t work without water.

However, they don’t use a lot of water, so you shouldn’t be worried about that. It’s estimated that only up to 1% of the water consumed by a household is consumed solely by a garbage disposal unit.

Choosing A Quiet Garbage Disposal

So, you’re looking for a garbage disposal, but not any would do. You’re looking for a specific product, one that won’t produce a lot of noise.

Well, if a quiet garbage disposal is what you’re looking for, you came to the right place. There are several factors that determine how much noise a garbage disposal will produce.

Most people will agree that using a small garbage disposal unit will guarantee you won’t have to face a loud unit. If you want to check out the best small garbage disposals available on the market today, click here.

It’s true that the motor is the loudest component of the garbage disposal, but that doesn’t necessarily mean that a smaller unit will automatically be quieter than a larger one. The amount of noise produced also depends on other factors, and it often happens that the quietest unit manages to incorporate a large number of the following factors.

  • Noise Insulation Features

    Most manufacturers choose to implement noise insulation features in their larger models to block some of the noise the motor produces. These insulation features are usually called different depending on the manufacturer, but they all work in the same way.

The noise insulation is usually a thick padding that wraps the garbage disposer, and its role is to reduce or block the noise produced by the motor. The thickness of the insulation padding is important, but so is the technology behind it. Some materials are better at sound insulation than others, so they can be thinner and still block more noise.

However, you should keep in mind that the noise insulation feature usually costs extra, so manufacturers avoid installing them on cheaper, smaller units. You will most likely find this feature on medium or large units.

  • Materials Used

    The materials used in the construction of the garbage disposal also have a part to play in the noise they produce. Low-quality materials will often be louder than high-quality ones, and the way they’re assembled also matters. When a manufacturer uses high-quality materials like stainless steel, they are also better assembled. This will lower the amount of noise they produce when the unit is working.

  • Installation Assembly

    You might think that the installation assembly only has a part in waterproofing the garbage disposal. In fact, the installation assembly has more than one role, each of them important for the garbage disposal as a whole. One of these roles is to lock the disposal unit in place, so it won’t vibrate.

disposal 4When the garbage disposal vibrates, these vibrations are transmitted to the closest object, which is the sink. Since some sinks are made out of stainless steel, copper, or cast iron, they are prone to sound loud when they vibrate. Composite and granite sinks are better at stopping the vibrations, but they will also produce some noise.

Here’s some advice.

If your garbage disposal produces loud noises, the first component you should check is the installation assembly. Make sure the disposal is snugly screwed into the assembly. If it isn’t, tighten the connection. When you believe the garbage disposal won’t shake in the assembly, start the unit again. If the noise is still there, check out the other components.

Garbage Disposals FAQ

  1. Can a garbage disposal grind through bones?

Well, there’s no definitive answer to this question. It all depends on the garbage disposal model. Even if they have the same motor capacity, some disposers are better than others because they work differently. Some models use a single-step grinding process, while others use a 3-step one. Some start their engine slow, while others start them at their maximum capacity. All these features make a difference.

As a rule of thumb, you shouldn’t try grinding through bones unless you own a 3/4 HP or a 1 HP unit. Even if you own such a large unit, you should only try to grind through small chicken bones and thin pork bones, not large ones.

  1. Is a garbage disposal safe to use around children?

As long as you set up the start/stop button in a place small children can reach, the garbage disposal should be safe to use. You should educate your children about the garbage disposal from an early age. Explain that this appliance is not a toy and that they shouldn’t use it, especially when you’re not in the room.

If you’re concerned about accidents that might happen when you’re away from home, we recommend you choose a batch feed garbage disposal. These units won’t start unless you insert the stopper or the cover. They are safer because the stopper/cover won’t allow small hands to enter the disposer’s hole.

If you want to make sure that your kids won’t start the unit when you’re not around, you can choose a batch feed model and hide the stopper/cover when you leave home. The model’s design won’t allow it to start without using one, so it should be safer.

  1. Is It Better To Hardwire Or Plug In The Garbage Disposal?

This might be a matter of necessity or preference, depending on your electrical circuit. Simply put, some people might have to hardwire their units, while others can plug them into outlets without any problems.

If your kitchen electrical circuit is already close to its maximum limit, it would be better to hardwire the garbage disposal directly to your home’s main electricity circuit.

If the resistance responsible for your kitchen circuit can handle the extra capacity that a garbage disposal needs, you can simply plug the unit into an outlet.

You should also make sure that the local regulations don’t require you to hardwire the garbage disposal before choosing a model.

  1. My garbage disposal smells really bad. What can I do to remove the smell?

If your garbage disposer produces a musty smell, you should clean it. To find out how to properly clean a garbage disposal unit, you should read our 7 Ways To Remove The Musty Smell guide.

  1. Do I need to keep the water running while the garbage disposer is working?

Yes, you should let the water run while you’re using the garbage disposer. You should only use cold water when the unit is working. If you use hot water, there’s always the chance of it encountering some fats and solidify them, leading to clogs.

You should also leave the water running for 10 – 15 seconds after the garbage dispenser has been turned off.

  1. What can I put in the garbage disposal?

A good garbage disposal unit can grind through many things. However, each model is capable of grinding through different types of garbage, depending on its build and power. You should always consult the instructions manual before you start using a disposer.

  1. My garbage disposal is jammed. What should I do?

Most of the times, a jam in your garbage disposal can be fixed using the disposer wrench the unit came with.

If a plumber installed your unit and you don’t know which is the disposer wrench, you might want to check the cabinet under the kitchen sink, maybe he left it there.

If you can’t find the disposer wrench, you can use n 1/4 inch Allen wrench instead.

The wrench will fit on the bottom of the disposer. This will enable you to manually move the grinding plate. Moving the grinding plate back and forth can loosen the jam.

  1. Can using a garbage disposal unit clog my pipes?

Well, there’s no denying that using a garbage disposal unit will increase the volume of waste that goes through your pipes. The waste particles might also be somewhat larger than those of the waste you’ve previously flushed.

However, this won’t be a problem for most users. If you don’t have any pre-existing problems with your plumbing, you shouldn’t encounter any when you use a garbage disposal, either.

If you already have some issues with clogging and sewage back-ups, you should not install a garbage disposal unit until you fix them.

  1. Sometimes water backs up into my garbage disposal when I use the dishwasher. Why?

The garbage disposal unit and the dishwasher use the same drain, so they’re somehow connected. When you use the disposer to grind up food scraps, and you don’t pay attention to flush the unit properly before turning it off, the grind down particles can lead to clogs.

Because food is clogging up your drain, the dishwasher can’t flush in it, so the water it uses will back up into your disposal and then the sink.

To make sure this doesn’t happen, use a copious amount of cold water when the disposer is running, and leave the water running for 10 – 15 seconds after you turn off the garbage disposer.

If you want to clean your drain, you should start by un-jamming the garbage disposal.

  1. My garbage disposal doesn’t start. What’s wrong?

There are multiple reasons why your garbage disposal unit won’t start when you turn it on. The most frequent causes are a fault in the wall switch, a fault in the unit’s start switch, or a faulty motor.
