[text_block_nav title=”What is a Garbage Disposal”]

What is a Garbage Disposal

A garbage disposal is a device fitted under the kitchen sink. It Is typically used to tear food waste into super minute pieces that won’t jam pipes. The device connects the pipe to the drain. Food waste passing through the machine gets torn into very tiny pieces which are approximately 1 – 2 mm in size. As such, the particles can go through the piping without blockage.

Disposing food waste in garbage results in toxic greenhouse gases! How?
Food waste discarded in the garbage will eventually deposit in a landfill where it decomposes producing methane gas, harmful to the environment.

Go green! Use a garbage disposal.

When utilizing a garbage disposal, food waste ends up in a septic tank or an underground sewer where it can be used to produce green, renewable energy.[/text_block_nav]

[text_block_nav title=”How does a Garbage Disposal work?”]

How does a Garbage Disposal work?

Contrary to what most people think, a garbage disposal does not work like a blender. It does not have spinning blades to chop and break down food waste.
Unlike Blenders, garbage disposers have lugs or impellers, positioned on a spinning plate. The spinning plate and impellers use inertial forced directed away from the center of the plate continuously pushing food waste scraps into a fixed grind ring.

The grind ring splits down the scraps into microscopic particles, essentially dissolving them. Once the food waste is grounded, the running water washes the shredded bits through the grind ring and away from the disposer, into the wastewater piping.

The shredded waste will then flow into a septic tank or to a wastewater treatment plant.[/text_block_nav]

[text_block_nav title=”What can go down a Garbage Disposal?”]

What can go down a Garbage Disposal?

The following items will go down your disposal safely:

Egg shells: Not only do eggshells help in cleaning your unit, but they also sharpen the blades of the garbage disposal.

Small bones: Accidentally, if some few small bones fall into your disposal, don’t press that panic button.

Fruit scraps: Most fruit scraps especially from grapes, bananas, berries, apples, and oranges, can go down the garbage disposal. Additionally, they end up freshening the drain.

Vegetable scraps: Almost all vegetable scraps will go through the garbage disposal without damaging the unit. However, there are some with a lot of fiber and as such might overwork the disposal. Examples include asparagus, artichokes, corn husks and banana peels.

Coffee grounds: Can coffee grounds go down a garbage disposal? There are mixed answers. However, it is agreeable that little amounts of coffee grounds can go down the garbage disposal without issues. Coffee grounds do also leave a fresh smell in the drain. However, disposing of large amounts is discouraged, because they end up collecting in pipes and causing blockage since grounds the grounds contain oils.

Citrus Skins: Citrus fruits rinds are one of the recommended naturally cleaning agents that you can use in your garbage disposal. Cut the fruit peels into small pieces before tossing them into the disposer.

Cooked meat scraps: Meat pieces leftover from meals are okay if they go into the garbage disposal when washing dishes. However, avoid substantial amounts or big pieces going into the unit.[/text_block_nav]

[text_block_nav title=”What can’t go down a Garbage Disposal?”]

What can’t go down a Garbage Disposal?

Although the following items are biodegradable they should not be thrown into your garbage disposal:

Banana peels: Highly fibrous fruit peels such as banana peels are not suitable for the garbage disposal. Instead, throw them in the compost or trash bin.

Fruit pits: It is best to throw fruit pits into the garbage or compost if you have one. Don’t put them in your disposer.

Grease: Who pours grease, oil and highly fatty things into their disposal? Oil, grease, and Fats solidify into a big, dirty mass which will eventually clog the pipes.

Shrimp shells: Tossing shrimp shells into the garbage disposal will yield a bad odor. Likewise, they are quite hard for the disposer.

Onion skins: Onion skins are also a no-no for the garbage disposal.

Pasta and Rice: These two expand and clog the pipes. Avoid throwing them into the disposal.

Large bones: Do not shove large bones into the disposal. Put them away in the trash bins or compost.

Nuts: Nuts are a no-no for your garbage disposal. Don’t put them there.

Potato peels: Highly starchy skins or products are not ideal for the disposal. It is advisable to throw them in the compost.

Corn husks: Corn Husks just like banana peels are super fibrous. Throw them in the compost. They will significantly reduce the lifetime of your disposal. Husks force the machine to work hard to break them down.

Artichokes: A number of users have had their disposal broken down by artichokes. Since they are hard to grind, they get caught in the disposal blades, often leading to a breakdown.

Asparagus: Highly fibrous veggie. Treat it like the corn husks; dispose into the compost or trash bin.

Never contemplate throwing shells (apart from egg shells) broken glass and cigarette butts into your garbage disposal. Actually, why should you?[/text_block_nav]

[text_block_nav title=”Things to consider before installing a garbage disposal system”]

Things to consider before installing a garbage disposal system:

There are some things you need to consider when thinking of installing a garbage disposal in your Kitchen.

Is a garbage disposal allowed in my locality?

Before you buy a garbage disposal system for your home, it is essential to talk to your local authorities who are responsible for maintaining the sewer systems to inquire about their policy on garbage disposal installation.

In some areas, local governments limit the use of garbage disposal systems, either because of inadequate water supply or faulty sewer systems.

There are areas where the garbage disposals are not allowed at all, while in other areas a special permit is required.

How big is my Septic Tank?

Your septic tank determines if you can install a garbage disposal system in your home. If you have a small septic tank, it will not be able to sustain a garbage disposal system and meet the needs of your home.

The system uses a lot of water; your septic tank must be big enough. Contact either your building inspection body or a health officer to advise you. They will check whether the septic tank is sufficient or if you need a bigger one.

Alternatively to solve the issue of a small septic tank, keep it empty most of the times. Note the cost implication of the same.

Can I afford the increase in my water bill?

In areas where there is inadequate water supply or water shortages are regular, installing a garbage disposal is not advisable.

Considering it needs lots of water for disposing of the food waste every time it is running, there will be a significant increase on your water bill.

Is my plumbing set up to use a garbage disposal?

Do you experience frequent problems with your plumbing? Installing a garbage disposal will only serve to increase the plumbing issues.

Does your plumbing system block often? Adding a garbage disposal will aggravate the problem by increasing the quantity of solid waste in your waste piping system, leading to more clogging.

We highly advise that before you decide to buy a garbage disposal system; (i) ensure there are no problems your septic system and (ii) your septic tank is either enlarged or emptied often.[/text_block_nav]

[text_block_nav title=”Choosing which Garbage Disposal to buy”]

How to choose which Garbage Disposal to buy?

Deciding which garbage disposal best fits their needs is a challenge for most folks.

Pricing is not the most critical factor. Just because a garbage disposal costs more does not mean it is the best for your household. You will be surprised to find an affordable garbage disposal as the best fit for your needs.

It is crucial to consider factors such as how often the garbage disposal will be in use and the size of the family in the household.

We are providing a comprehensive list of fundamental things you need to know before buying the best garbage disposal unit.

A proper garbage disposal will efficiently deal with your typical kitchen waste with no issues. Nevertheless, the quantity and type of waste that is common in your household help in determining the size of garbage disposal best suited for you.


If you have a small family, a cheaper and smaller garbage disposal will work for you. In most cases, a 1/2 Horsepower (HP) or a 1/3 Horsepower will be sufficient. Most 1/2 HP Continuous Feed Operation Garbage Disposers, can deal with large amounts of food leftovers.

If your household has around four family members and the garbage disposal will be in use a lot, a 3/4 Horsepower (HP) unit is recommendable. Most 3/4 Horsepower units with Continuous Feed Operation can handle tougher and larger amounts of food waste such as small bones. These units are sturdy and do not jam easily. They do not break easily even when items such as big bones accidentally find their way into the units.

If your family has more than four members, a 1 HP garbage disposal is best. One Horsepower disposer units with a continuous feed operation can cope with frequent work and break down most of the tough food waste.

Noise and Vibration

vibration and noise - garbage disposalVibration and Noise are concerns that buyers have when choosing which disposers to buy. The best garbage disposal units available today are less noisy and make fewer vibrations than earlier units.
Noise and vibration occur for two reasons:

(i) the connection between the disposer unit and the kitchen sink;

(ii) the garbage disposal unit.

Superior mounting systems are used in the best garbage disposals to reduce noise by minimizing the vibration from the disposer to the countertop or sink.

Apart from the mounting, another critical element in reducing noise is insulation. Look out for proper insulation around moving parts, anti-vibration tailpipes or sink mounts and sink baffles. Some garbage disposal units use soundproofing materials.

Use of nylon to insulate the grinding chamber in Waste King Units further reduces noise in the units. Due to the “Sound Seal” technology in Insinkerator garbage disposers, they are quietest units on the market.

Excessive noise from your garbage disposal in an indicator that the unit has worn out parts or is damaged.

Batch Feed vs Continuous Feed Garbage Disposals

Batch feed vs Continuous Feed Garbage DisposalContinuous feed garbage disposals are the best and most popular because they are easy to use and their continuous operation saves time. Immediately you put waste in the sink; the garbage disposal starts grinding. If you are looking for convenience, you will not go wrong when you buy continuous feed garbage disposal.

Batch feed garbage disposals, although not as popular are much safer to use. Their grinder entrance hole is covered reducing the chance of both injury and breakdown. Items cannot accidentally fall into the disposer.


Any garbage disposals worth its salt comes with an easy to read and follow instruction manual. Furthermore, all the components needed for installation are included in the packaging. You should be able to install the unit using the manual without engaging a plumber.



Septic Tank Compatibility

septic tank - garbage disposalAny garbage disposal that you choose to buy must be compatible with your septic tank. Small septic tanks are not capable of handling a garbage disposal; you will damage the sewage system.

Installing a three-stage grinding disposal and regular emptying of the septic tank can fix the problem. However, the ultimate solution is to expand the tank.


The Grinding Stage

Grinding Stage - Garbage DisposalAn efficient garbage disposal unit grinds up waste into tiny pieces that cannot block sewage pipes or septic tanks.
Grinding stages depend on the model and brand of the garbage disposal unit. One to three grinding steps are available, depending on the manufacturer.

Most of the cheapest garbage disposals only use one stage in their grinding process. Having one grinding stage does limit the disposer’s capacity to crush waste into tiny bits. Additionally, the kind of waste it can handle efficiently is also limited. Units with only one grinding stage need more water to flush the waste through the sewerage system.

Garbage disposals with two grinding stages work the same as stage one units however they further shred the food waste in the second phase. In the second stage, the food waste is liquefied to prevent blockage of the sewerage system. Compared to one-stage units, disposers with a two-stage grinding process shred tougher waste, while using fewer amounts of water.

The best-in-class Garbage disposals utilize a three-stage grinding process. Apart from breaking down waste into smaller bits than stage one and stage two grinders, they will shred the most hardened food waste effortlessly. Apart from doing what both stage-one and stage-two grinders do, stage 3 disposers also liquefy the waste further.

Further liquefication ensures there is no blockage of the sewerage piping and much fewer quantities of water are needed. 3 stage grinding units can dispose of grains of rice. However, it is not advisable to put rice and pasta into disposers because they expand in the pipes and can cause clogging.

The Mounting

mounting - garbage disposalThe mounting is the linkage between the garbage disposal system and the sink or kitchen counter. The mounting type used depends on the manufacturer. They should be easy and quick to install.
The best mounting types in the market are by InSinkErator and Waste King.

InSinkErator’s Quick-Lock mounting system is made of stainless steel. It is available in all its ‘’Evolution Series’’ models and also works with the older ‘’Badger series’’ models.
The quick locking mount makes it easy to fit a new garbage disposal or to replace an existing one.

Waste King offers two types of garbage disposal mounting systems; the three bolt and EZ mounting systems.

The three bolt mounting lasts longer because it is made with stainless components.

The EZ mount system from aluminium and plastic, it includes a removable splash guard which is easy to clean.


durabilityIt goes without saying; the best garbage disposals are long-lasting. Durable disposers grinding chambers and components are made of non-rust stainless steel. Additionally, they have anti-jamming and automatic reverse systems. A Disposer with an auto-reverse automatically reverses the grinders when it detects a jam. This reversal unblocks the unit without your input.



disposer-size - garbage disposalWill the garbage waste disposal you intend to install fit in your kitchen? The unit’s power mostly determines the size of the disposer. Units with small motors are smaller in size while units with bigger motors are big. However, there are a few exceptions. It is crucial to measure the space under the sink before deciding which disposer to buy. In most cases when you are buying powerful garbage disposers, you will have to increase the space under your countertop or kitchen sink.

Warranty and Support

warranty and supportThe best garbage disposals come with a good warranty.
WasteKing units come with lifetime warranty. If a WasteKing disposer fails either because of a manufacturing defect or mechanical fault, it will be replaced or repaired at no cost.

InSinkErator garbage disposals have good warranties as well. When you buy any of their Evolution series units, you get a complete 7-year, parts and labor guarantee. Insinkerator has a “we come to you” 3-year and 2-year In-Home limited warranty for some of their units. Both warranties include free house calls, parts, and labor.

Before buying a disposer make sure the warranty support after sales service. Read the exact details of the warranty to avoid future misunderstanding.[/text_block_nav]

[text_block_nav title=”Difference Between continuous feed and batch feed garbage disposals”]

What is the Difference Between continuous feed and batch feed garbage disposals?

There are two types of garbage disposals; continuous-feed and batch-feed; you need to know them.

The continuous feed units allow you to continue adding food waste while the disposer is running. In contrast, in batch feed units you place the food waste in the disposer, put on the cap and then turn on the unit.

Both types of garbage disposal work the same; they grind and dispose of food waste reasonably well. Continuous feed and batch fee are both efficient, have the same kind of grinding chambers and similar horsepower ratings.

Nonetheless, there are advantages and disadvantages associated with each type. This section will help you understand the differences, pros, and cons of each type.[/text_block_nav][text_block_nav title=”Continuous Feed Garbage Disposal”]

Continuous Feed Garbage Disposal

This kind of disposer has a switch installed near the unit. Some units come with an electric switch fixed on the wall, while others come with an air duct attached to the sink.

When operating the continuous feed disposal, let the water flow through the drain for a few seconds, before switching it on. Running water through the drain cleans any leftovers from the previous grinding. Once the disposal is running, put the food waste continuously until you are done.[/text_block_nav]

  • Popular with many models available in the market.
  • Cheaper compared to the batch-feed garbage disposals
  • Very fast and easy to use
  • Waste is disposed quickly
  • There are no instructions to follow
  • There is no waiting for one batch to finish before the next batch can go in
  • Unsafe to use because it lacks a cover
  • It can throw scraps and bones outside of the drain because of its continuous operation
[text_block_nav title=”Batch Feed Garbage Disposal”]

Batch Feed Garbage Disposal

In a batch-feed garbage disposal, the user fills the drain or the chamber of the garbage disposal. Once its full, cover the unit with a plug and push. Pushing the cap turns on the disposal system. A batch-feed disposal does not need electric or air duct switch to work.
Once the current batch disposed of, add the next other one and repeat the cycle until all food waste is discarded.[/text_block_nav]

  • Very safe to use: the cap makes it safe to use for families with kids.
  • There is no spillage of garbage during operation.
  • No accidental falling of cutlery into the disposal during operation.
  • More expensive compared to continuous garbage disposals.
  • Takes more time to dispose of large amounts of garbage
[text_block_nav title=”Garbage disposal motor size”]

Which is the right garbage disposal motor size?

The size of a garbage disposal is directly proportionate to the motor size. A bigger disposal has more horsepower while a smaller disposal has less horsepower. Garbage disposals come with four types of motor size; one-third (1/3), half(1/2), three-quarter(3/4) and 0ne (1) horsepower.

One Third (1/3) Horsepower Motor

If you have a small family of about one or two, the one-third (1/3) horsepower is ideal for you. This motor is pretty small, making it cheaper. A little family does not cook regularly, and when they do, the volume of food waste generated is not much. A disposal with one-third (1/3) horsepower will be sufficient for such a household. This type has limited power to grind hard food scraps like bones. It does well with vegetables and soft food waste.

Half(1/2) Horsepower Motor

The half (½ ) horsepower motor is also a cheaper model that is recommendable for a family of up to 4 people. The disposal is affordable for most small families and is ideal for standard usage. However, it lacks enough power to grind hard things such as bones. This type is easy to install and comes with a stainless steel chamber. The stainless steel chamber makes its which make them more long-lasting and reliable than 1/3 horsepower models as well as easy to clean and maintain.

Three-Fourth (3/4) Horsepower Motor

Three-quarter horsepower motors have more power than the models mentioned above. However, they are highly priced as well. These models are ideal for ordinary families of about five people. Features include stainless steel chambers which do not rust easily and can be cleaned quickly. Compared to other models with less horsepower they bigger. Installing this type of disposal requires professional assistance. These models can grind hard food waste, jam less and are less noisy.

One (1) Horsepower Motor

One (1) Horsepower motors are top of the range garbage disposals and cost most than all the other models. They have the most power making them ideal for households with more than five members. Most food waste is disposed of by this disposal without any difficulty. They can grind bones, are less noisy and come with other additional features.
