Garbage disposal aka garbage disposer — as the name suggests — adds convenience to your daily task of removing waste. How? By grinding your garbage into fine particles, it prevents your drain pipe from getting clogged. You must already know that there are two types of garbage disposers — batch feed and continuous feed disposals. However, there are several other aspects that you should consider when buying the next disposer. Check out this comprehensive guide on how to pick the right garbage disposal for your home.

Which Type Is More Suitable for My Needs?

The function of all garbage disposers is essentially the same. They grind food — mainly non-compostable scrap items such as meat and fat. These then are sent down to a septic tank via your drain pipe. As already mentioned, garbage disposals come in two types.

Continuous Feed Disposals

These will grind your food waste continuously. If you are looking for cost-effectiveness, then this option is the most ideal, convenient, and common choice.

Batch feed disposals

These will grind your food in batches. It, however, offers some advantages over the former option such as minimizing risks via injury or flying particles. This is because it does not turn on unless you place the cover in place.

What Is the Level of Horsepower I Require?

Garbage disposal motors arrive in horsepower ranging from 1/4 HP to 1 HP. The horsepower specification also determines the cost of your model. Higher ratings mean that the disposer can grind heavy loads better. They are more suitable for larger families and homes that do frequent cooking. On the other hand, if you are a small family, you can go for the lower horsepower models.

What Motor Type Should I Choose?

In order to pick the right garbage disposal, another factor that you should consider is the motor type.

Induction Motor

Usually, disposers feature an induction motor — which generates less noise and is also reliable and durable.

Permanent Magnet Motor

The other type is the permanent magnet motor — which is light and runs at variable speeds plus higher RPM. It is best to quickly grind small loads.

What About the Size of My Septic System, Volume of Water Consumption & Plumbing Requirements?

Size of Septic Tank

Sometimes, your area’s septic system might not prove big enough to accommodate the waste from a disposer.  Therefore, ask your building inspector if an upgrade is necessary. Otherwise, it might simply suffice to empty your tank more often.

The Volume of Water Usage

According to minute-per-day use figures, a garbage disposal uses approximately 2.5 gallons of water per minute. Hence, this factor must also be considered since it will affect your water consumption level and water bill.

Plumbing Requirements

If your plumbing is prone to frequent clogs, better get it fixed before installing a disposer. Otherwise, the added waste will increase your problems.

What Type of Component Material Should I Choose?

Grinding chambers and grind components are made from mainly three types of materials: plastic, galvanized steel, and stainless steel.

Stainless Steel

Stainless steel grinding chambers ensure maximum resistance against corrosion and hence add to the durability of your disposer.  


You can also go for thermoplastic polymer grind chambers — which also offer rust and corrosion resistance.

Galvanized Steel

Galvanized steel, on the other hand, lasts long, but is prone to rust and corrosion.

What Other Additional Features Can I Consider?

Some other features that you can consider are:

Electric Cord

Certain models come with an electric cord — relieving you from the process of hard-wiring the system.

Auto Reverse Mode

If your disposer has an auto reverse mode if will feature a blade-oscillating ‘jaminator’ to prevent the spinning blades from getting jammed.

Quick-mount Neck

Check if your disposal has a quick-mount neck. You can then go for a DIY installation.

Safety Cover

If your disposer comes with a safety cover, your disposer will not be turned on unless the cover is in place.
