Garbage Disposal Buying Guide

Now that you’ve read the reviews for the best garbage disposal, you likely have an idea of what the perfect garbage disposal is for your kitchen. Before you go haring off into the store and buy one, let’s talk about some other things you should know. For example, all of the garbage disposals we reviewed are continuous feed models. But did you know there’s another type that might work well for you?

Then let’s talk about the features that you should know about. From thinking about the noise level to the ease of maintenance, there are some very important things to know.

Types of Garbage Disposals

It's easy to think that the best garbage disposals come in one size fits all models, but they don't. They actually come in two different types. The first is a continuous feed model and the second is a batch feed model. There are some key differences in how these garbage disposals work so let's go over that and cover some of the pros and cons.

  • Continuous-Feed Models

This type of garbage disposal is the one that you probably think of when you hear about garbage disposals. You put scraps of food in and turn the switch and everything is ground up and washes down the drain. This type of garbage disposal is the easiest to use because you can simply add new scraps as the old scraps are ground up. By far, this is the most common model of garbage disposal that you will find on the market and it is fairly easy to install for DIY'ers with moderate expertise.

o Pros: the most significant plus to this type of garbage disposal is its ease of use and its ease of installation.

o Cons: this type of garbage disposal is also the most dangerous. That is because the open neck allows you to feed scraps while the machine is running. Everyone has seen horror movies where somebody gets their hand trapped in the garbage disposal and it gets turned on. Thankfully, with the use of safety covers, this sort of accident can be easily prevented.

  • Batch-Feed Models

A batch feed model of garbage disposal is one where you load up the disposal Hopper and it is then activated after the stopper is in place.

o Pros: this type of garbage disposal is the safest because you don't turn it on until after the cover has been put on and the garbage disposal has been filled. So if you have children, you don't have to worry about their fingers.

o Cons: batch feed models of garbage disposals are usually more expensive than a continuous feed. Also, because of needing to fill the hopper before use, these generally take longer to finish the job than a continuous feed model.

Features to Keep in Mind When Searching for the Best Garbage Disposal

Now that you know the two types of garbage disposals that there are, let's talk about some of the features that are common between the two. While not all of these features are essential, most will have some impact on your purchase decision.

  • Noise

Let's face it, garbage disposals are noisy. After all, they are a bunch of blades whirling around grinding up waste products. How can you minimize that noise? Well, manufacturers do this in several ways. First is by insulating the grinding chamber. The grinding chamber is where all of the action actually takes place. And by wrapping that in a material that reduces noise and vibration, it helps to make your garbage disposal the little quieter.

Look for things like SoundSeal Technology from InSinkErator, or Soundshield from Moen. These are just different names for different types of insulation for your garbage disposal.

Another way that you can reduce the noise from a garbage disposal if you like a certain model, is by investing in a cap. The open mouth of a garbage disposal is a funnel that transmits sound quite readily. By clogging that opening, you will reduce the amount of sound that you can hear from your garbage disposal.

  • Size

When we talk about the size of your garbage disposal, we aren't talking about the actual length. While you should take into consideration how big your garbage disposal is when it comes to space you have underneath your sink, what you really want to look at when it comes to size is how much your garbage disposal can handle. The key determining factor in picking out an appropriately-sized garbage disposal is by thinking about the number of people that you have in your household. Here’s a short chart to help you find the right size for you and your loved ones.

  • Household Size Cook Often? Horsepower Recommendation Grinding Uses
  • 1-2 People No 1/3 HP – Light Scraps Soft food, fruit rinds, meat trimmings
  • 2-4 People No 1/2 HP – Scraps and Leftovers Cooked meat, seeds, small bones from fish
  • 2-4 People Yes 3/4 HP – Tough Scraps Artichokes, cooked meat, small chicken bones, vegetable peels
  • 4+ people Yes 1 HP – All Food Scraps Fibrous foods, vegetable peels, raw or cooked meats, small bones from chicken or fish
  • Electric Cord

Some garbage disposals can be plugged into an existing outlet for power. Others require hardwiring in order to be used. And most cases, a separate power cord that can be plugged into the wall will save you quite a few steps in the installation. However, keep in mind that all of your garbage disposals should be hardwired to a light switch which will turn them on. This installation cost should be calculated into your overall budget for your garbage disposal. Of course, if you are able to do it yourself, and you are comfortable with working around electricity, that won't be a concern.

  • Auto-Reverse Mode

One of the worst things that can happen to a garbage disposal is if it gets clogged or jams. If this happens then you are stuck with the task of clearing the jam manually. However, some garbage disposals come with a handy feature called Auto reverse mode.

What happens is if the garbage disposal detects resistance over a certain amount, the blades and the motor will automatically spin in the other direction for a short period of time to try to clear the jam. This means that it's safer because you don't have to stick your fingers into the garbage disposal. If your garbage disposal jams and you clear it, the blades may still move quickly because of power and energy still in the blades.

  • Horsepower Ratings

When it comes to horsepower, you might think that going for the maximum horsepower possible is the best thing. However, this might not always be the case. 1/2 horsepower model is more than capable of clearing and eliminating most food scraps that a one to two-person household will eat it. Of course, if you plan to throw chicken bones into the garbage disposal, you are going to want something a little more powerful. Here is a chart that breaks down some horsepower ratings and what each one can handle in general.

Horsepower Use

1 HP Full Use. Use common sense. Depending on the grinder assembly, it may be able to handle larger chicken bones.

3/4 HP It can deal with more fibrous foods, including artichokes. It can also handle small chicken bones, such as wings or ribs.

1/2 HP Can handle small bones from freshwater fish. Also can deal with vegetable peels and small amounts of cooked meats

1/3 HP Limited Use. Smallest softest foods such as fruit peels and soft cereals. No bones or vegetable peels

  • Quick Mount

Some garbage disposals make it really easy to install on your own. Some manufacturers have quick mounting systems. For example, InSinkErator has a system called Quick Lock, while Waste King calls their quick mounting system "EZ Mount." These are designed to make installing your garbage disposal as easy as possible. That being said, if you’re doing the installation on your own, you still want to have a full set of tools at the ready. Check your manufacturer’s installation material for a complete list of tools.

If you don’t choose to go with a quick mounting garbage disposal, you’re going to deal with a standard 3-bolt mounting system. Whichever you use, keep in mind that garbage disposals aren’t lightweight and some will require extra hands to hold them up while you get them installed into place. Another thing to keep in mind is that some quick mounting systems are cross-compatible. For example, KitchenAid’s system is designed to work with InSinkErator.

  • Safety Cover

Some garbage disposals are designed so that they cannot be turned on without a specific safety cover in place. While this is great when it comes to keeping you safe, you also have to consider the other side of the coin: what happens if you lose the cover? This is an important question. If you like the idea of a safety cover, companies like Gard Dawg Industries make specific garbage disposal guards that prevent fingers or hands from going where they shouldn’t, while still allowing you the space to wash away the refuse you need disposed of.

  • Grind Chamber Construction

When it comes to garbage disposals, the grinding chamber is where all the work gets done. Some are made of heavy-duty plastic; others are made of galvanized steel. The new fad is to make them out of heavy gauge stainless steel. Here are some pros and cons of each material and some things to know about them.

o Stainless Steel – When a disposal’s grinding chamber is made of stainless steel, then it can be called a stainless steel disposal. These are usually higher-end garbage disposals like InSinkErator’s Evolution series.

▪ Pros: Extremely stain resistant and resistant to corrosion.

▪ Cons: Heaviest of the three options. The manufacturing of stainless steel makes it about 3% heavier than galvanized steel. Not a lot, but it can add up. Stainless is also more expensive than the other two options.

o Galvanized Steel – Galvanized steel is dipped into zinc after it is made, which creates a surface layer that helps it be rust and corrosion-resistant. Unfortunately, over time, the galvanization can wear down.

▪ Pros: Durable and strong. Fairly resistant to rust, but over time and repeated wear, it can eventually rust.

▪ Cons: Middle of the road for the expense, but also fairly heavy.

o Plastic – A plastic grind chamber isn’t plastic like you think. It’s made of a high tech thermoplastic polymer, which is another word for stuff like Polyethylene or acrylics.

▪ Pros: Does not rust or corrode. The least expensive option of the three.

▪ Cons: Wears out the fastest of the three. It can be cracked easily if suddenly struck.

  • Warranty

Warranties are great to have for a garbage disposal. However, keep in mind that warranties only cover manufacturer defects. Most warranties will never cover wear and tear on a garbage disposal, so a warranty may not be worth much, especially with all of the use that a garbage disposal can undergo.

That being said, however, you should always know what your warranty covers and how to get warranty service. There may be cases where you can make a claim that your garbage disposal failed because it was not manufactured properly.

Also, keep in mind that manufacturer warranties will not cover the installation or removal of the garbage disposal, nor do they usually cover shipping. As always, reading the fine print is Paramount when it comes to getting the most value out of whatever manufacturer's warranty is offered.

Things to Consider Before Buying a Garbage Disposal

Is A Garbage Disposal Appropriate In My Area?

Garbage disposals are not allowed everywhere. For example, in Los Angeles, commercial garbage disposals in Food Service establishments are strictly prohibited. So how do you know if a garbage disposal is allowed for you? The easiest way is to contact your local municipality or Township Authority and ask them.

In some cases, they will recommend that instead of using a garbage disposal, simply throw the food scraps away into your trash can because food scraps are shipped to landfills anyway. Additionally, food scraps are known for adding nitrogen to water. So if your local area is trying to reduce the nitrogen load of water, you may not be allowed to install a garbage disposal.

● Homes With Septic Tanks

If you are Township does allow you to get a garbage disposal, they may require that your septic tank is upgraded or emptied more frequently. Again, the best bet is to check with them to see what the code regulations are.

● Is The Extra Water Use Worth It?

When you use your garbage disposal, you need to be running the cold water the entire time that your disposal is on. You should also be running the water for 20 to 30 seconds after the disposal stops. Tallied up, this can be a lot of water to use.

● Now there are ways around using fresh potable water, including using gray water recapture systems or rainwater, but for most users, you can be looking at increasing your water usage by up to a thousand gallons a year. You will have to determine if this impact on your local ecosystem and on your water bill is worth the convenience of the garbage disposal.

● Is The Plumbing Up To The Task?

If your plumbing is already prone to clogs or backups, then adding a garbage disposal and the ground of waste that is sent through can also create more problems. If you are determined to get a garbage disposal, it is recommended that you have your drain system repaired before installing a garbage disposal.

Maintaining your Garbage Disposal

Most garbage disposals are meant to be zero maintenance. But there are definitely some things you can do to keep your garbage disposal running as smoothly as it did the day you bought it. Here are four things that you should definitely be doing when operating your garbage disposal.

First, everybody knows that you should be running the water when your garbage disposal is operating. However, not everybody knows that you should not be using hot water. While hot water is not going to damage your garbage disposal, it can cause fat to congeal and stick to the blades. Coldwater ensures that the fat solidifies and is ground up into smaller pieces and washed away.

Secondly, avoid tough and fibrous materials in your garbage disposal. That includes things like nuts or Peach pits or things that are tougher to crack. This type of food waste can damage the Grinders and grind chamber. Fibrous waste like celery can actually tangle in the blades and grind assembly causing them to slow down and eventually Jam. secondly, avoid talk and fibrous materials in your car disposal.

That includes things like you nuts or peach pets or things that are tougher to crack. This type of food waste can damage the grinders and grind chamber. Fibrous waste like celery can actually tangle in the blades and grind assembly causing them to slow down and eventually jam. Additionally, don't send pasta to your garbage disposal. Pasta will stick and is notorious for creating clogs.

Thirdly, use ice. Ice can be used to clean your garbage disposal because as it grinds the ice chips will help to scare away smaller particles that may be adhering to the chamber and the grinder. Just make sure that you put the rubber stopper over the opening to prevent ice chips from flying out. You can also combine citrus peels with the ice to help clean and keep everything smelling fresh.

Lastly, follow your manufacturer's directions for using a degreaser. A degreaser used in accordance with their recommendations will help keep oils and fat from building up and clogging. This also will help eliminate odors coming from your garbage disposal that can be caused by rancid fat.


  • Are Garbage Disposals One Size Fits All?

Physically, yes. That is because all standard kitchen sinks have drain holes that are 3.5 inches in diameter. Every garbage disposal manufactured is made to the standard. If you have a custom-made sink that has a different size drainage hole, then you will need to find an accessory that will adjust the opening to fit that size

  • Do I Need A Plumber To Install A Garbage Disposal?

Installing a garbage disposal will usually take between two to four hours. This can be changed whether an outlet is nearby and what the current conditions of your sink and plumbing are.

Whether or not you need a plumber depends on how comfortable you are with working around your plumbing system. Keep in mind, that if you do not have a GFCI outlet near your sink oh, you will probably also need an electrician. Especially if you plan to hardwire the garbage disposal to a wall switch near your sink.

  • What Should Not Go Into A Garbage Disposal?

When it comes to what you should not put in a garbage disposal, Common Sense rules the day. For example, you should never put non-food products into your garbage disposal. That means no paper products, definitely no cloth products, and nothing metal. Depending on the power of your garbage disposal bones may be an issue. If you have a two or three-stage grinder then it should be able to handle bones. But if you've gone for a more economical model, throw the bones in the trash.

Another thing not to put in your garbage disposal is celery. This also includes other fibrous foods like corn husks or asparagus. Also, avoid coffee grounds because they do not rinse out very easily. Another thing to definitely avoid putting down your garbage disposal is potato peels.

Because potato peels are full of starch, they can eventually cause a starchy buildup which causes a clogged or a jam. Stay away from other starchy vegetables if you can help it.

  • How Do I Clean My Garbage Disposal?

One of the easiest ways to clean a garbage disposal is by using vinegar and baking soda. Simply sprinkle half a cup of baking soda and your garbage disposal then gently pour a cup of white vinegar. The mixture is going to fizz, bubble and froth. Let it sit for 5 to 10 minutes.

Then turn the hot water on and your garbage disposal on and rinse it clear. According to your manufacturer's suggestions, use a degreaser every few months to clean out any fat solids. If you are concerned about how your garbage disposal smells, use lemon peels or orange peels to give it a nice fresh citrus scent. Above all, never use any harsh chemicals in your garbage supposed as that can react badly with the material that your grinding container is made of and it's also extremely bad for your septic pipes.
