Best Garbage Disposals Buying Guide

So, what do you look for in a good garbage disposal? Scouring the internet and stores for the best disposal unit is not always an easy thing. That’s why we wrote up this guide just to help you find your new garbage disposal easily. However, you’re probably asking how you could know the specific garbage disposal that is best for your requirements. And that’s what this guide is about!

Type of garbage disposal

The units come in different shapes sizes and models. You could choose the continuous feed garbage disposal that allows you to put scraps of food and then turn on the switch. It’s the easiest used because oil need to do is add food waste and the unit does the rest. However, the open neck requires a safety cover to prevent injuries.

The batch feed garbage disposal requires you to load the trash first before you activate it. It’s safer than the continuous model but more expensive. They also take longer to do the job.

Noise insulation

Garbage disposals can be noisy and make your kitchen rowdy. But, the majority of manufacturers are trying to alleviate this by insulating the grinding chamber.

The chamber is mostly where the noise comes from because of the rotating motor and vibration. So, some companies have come up with sound shield and subsea technologies that help to reduce the noise isn’t vibrations emanating from the unit.

Alternatively, you may want to invest in a cap whereby you shut the mouth of the disposal. Remember, the funnel that transmits the sound of what happens in the chamber. So, closing it reduces the sound that you hear.

The size of your disposal

These units do not have the exact same length, or the space that it consumes. You realize that your sink can only accommodate a small item. You don’t want a bulky tank beneath your sink. Especially when you have a deep sink, you want one that’s shorter.

So, think about the number of people in your household and use that information to determine the kind of disposal that would serve you right. Also, find a model that fits well with your septic system.

The auto-reverse feature

In case the garbage disposal clogs or jams, you may have to solve it manually. But, if you are lucky enough to have one with the auto reverse feature, then you can just engage it and it will unclog itself for you.

This mode simply detects resistance of any amount and then decides to spin into the other direction. Reversing for short time allows all material that’s jamming up to move away.

And, the blades cut and crush the waste when they spin to the opposite direction which allows the material to be thrown into the drain. It’s important that you look for units with this out or reverse feature if you do not want to have to worry about jamming and clogging.

Horsepower of your disposal

Sometimes you might have the misconception that disposals with high horsepower are the best. However, you realize that it might not fit your case.

1/2 horsepower could do a lot of clearing and deal with your food waste better than the ore powerful motor especially if you are few in your household. Of course, it will not lather well with chicken and fish bones. Those will require a more powerful horsepower unit.

As a rule of the thumb, use 1 horsepower garbage disposal for larger families and to handle harder things such as fish and chicken bones.

The three quarter horsepower garbage disposal can act on small chicken bones especially the ribs and wings. This includes artichokes and other fibrous food wastes.

The half horsepower is good for bones from freshwater fish. Vegetable peels and cooked meat could go down the drain with this disposal.

Then, the 1/3 HP is the smallest and is meant for limited use. It handles soft foods including serious and fruit peels. Please don’t throw the bones or vegetable peels in here because those should go to the trash can.

Easy to mount and maintain

Garbage disposals are appliances that necessary don’t need the intervention of expert. If you are using InSinkErator, for example, you just have to engage the quick lock system just like the Waste King has the EZ Mount. These technologies make the installation process simple. Look for units that will not require extra hands to install.

The strength of the grinding chamber

The grinding process of a garbage disposal is probably the unit’s most crucial part. And, for that reason, you need the grading chamber to be strong enough to handle the waste.

 The grinding chamber is mostly stainless or galvanized steel. Then, the exterior has some heavy plastic.

High-end garbage disposals such as the InSinkErator evolution series have stainless steel. The good thing about it is that it does not get stained or corroded. It’s also the heaviest and most powerful of the other options.

Then, the galvanized steel is corrosion resistant. Unfortunately, the zinc covering on top of the steel can sometimes wear away. And as you guessed, galvanized steel is heavier than plastic of course.

Then some of the cheaper garbage disposals come with a tough plastic grinding chamber. The thermoplastic polymer does not rust or corrode or react with anything, but it cracks more easily.

How Do Septic Tanks Work?

  • Garbage disposals make work easier by shredding the waste that goes into the septic tanks. A lot of people have issues with garbage disposals and deep sinks. The best garbage disposal for deep sinks should therefore be short enough to be accommodated in the installation. But also, it has to be fit appropriately with the piping that leads into the septic tank.
  • Septic tanks and systems are underground waste treatment infrastructure used by people living in rural areas that did not have centralized sewerage systems. These systems simply depend on nature and technology to treat kitchen drains laundry and bathroom water.
  • The septic tank simply works with help of bacteria. These little organisms break down all the waste matter and then decompose it safely. The system is supposed to take care of the bacteria so that the bacteria can in turn act on the waste.
  • The main components of a septic system are the tank, the drain field, and the soil absorption field.
  • The septic tanks work is to digest all floating mutton that includes oil, grease, fats, and anything else that floats.
  • Then the effluent from the septic tank goes into perforated pipes and chambers that release this waste back to the soil in a safe organic form.
  • The flow of this filth depends on pressure created by gravity or pumps. It’s supposed to make the effluent seep into the soil.
  • The end goal is to disinfect the wastewater before it gets to the environment. In short, when wastewater leaves your house, it goes into the main drainage pipe that leads into the septic tank. The septic tank is usually buried in a watertight condition.  Many people use fiberglass concrete or poly them to make the septic tank.
  • It’s in the tank that the wastewater is held to make the denser materials sink to the deepest part while the scam floats. There are compartments and chambers that prevent the sludge and scum from getting into the drain field before the treatment and digestion is complete. Only treated wastewater is allowed back into the environment.
  • Then, the liquid wastewater or the so-called effluent gets into the drain field. This shallow covered excavation comprises of loose unsaturated soil into which the wastewater filters.
  • The piping system is porous to allow the wastewater into the soil without saturating it. Then, the soil or sand allows the wastewater to seep into the ground. A flooded drain field could be an indication there is so much liquid and it needs quick action.
  • After the wastewater percolates into the soil, all the harmful bacteria, viruses, and pollutants have been removed. And, especially coliform bacterium that lives in the human intestines and human fecal matter is removed and the safe waste can now naturally be accepted by the environment.
  • However, the aerobic bacteria only act on organic substances. There for diapers cigarette filters or plastics might not get digested.

Garbage Disposal Problems And Solutions

Garbage disposals are machines just like any other, and they can malfunction. Here are problems your disposal might encounter.


Sounds should not be something to worry about at first. But, if you realize than it was quieter sometime back, then you should already begin to find a solution.

Waste machines might get clogged and jammed. Even the advanced models can still find themselves in this mess and you must find a solution immediately. Fixing the jam is not so difficult because the manufacturers themselves have a manual that anticipates such eventualities.

In case yours clogs, then you need to handle the drainage pipe properly. Most clogging happens in the drainage piping systems. So, you need to pay more attention to the drainage than to the disposal.

Are Garbage Disposals Good For The Environment?

Yes, a Study by the Oregon State Department finds that grinders are better than landfills. In fact, In-Sink grinding (ISG) tends to be more eco-friendly because it improves soil productivity and optimizes biodegradation.

In fact, the In-Sink grinding of food waste tends to have a greater potential for renewable energy because of the increased surface area for bacteria action.

Another survey by the energy department also suggests that municipal sewage systems encourage garbage disposals because they increase the potential of harvesting biogas.

Nearly 22% of Americans have a garbage disposal at home. So, noting that the septic tank is compatible with garbage disposal. But as you have seen, they are actually a great combination. Just buy one of the best garbage disposal for septic systems and make use of the anaerobic digestion to exploit biogas technology.
