Searching For The Best Garbage Disposal For Your Kitchen

I’ve got my personal preferences and my kitchen setup means that when I am looking for a new unit, my requirements will be different from yours, but here’s my guide to the top features to look for.

A garbage disposal unit, or garburator, fits neatly under your kitchen sink, and shreds food waste using a high torque electric motor spinning special grinding wheels to reduce food to tiny particles that can pass through normal plumbing to your drain. The main pricing difference is due to the power of the unit’s electric motor – stated as horsepower and generally in the 1/3 to 1 HP range, and the quality of the grinding components (cheaper units use galvanized steel, premium units use stainless steel components). A more powerful motor can grind and crush tough food waste without jamming.

Thanks to their convenience, the popularity of units keeps growing: with over 50% of homes in the US fitted with a disposer, and are growing in popularity in the UK and countries such as Sweden (which encourages their installation to help increase the production of biogas as a natural fuel bi-product).

Replacing a Garbage Disposal Unit

Disposers don’t last forever: sometimes the electric motor will burn out or they simply go wrong and that’s when you’ll need to start thinking about buying a replacement. The good news is that it’s a very straightforward process to replace a unit – and the major manufacturers have standardized on a twist-and-lock fitting process that allows anyone with basic DIY skills to replace a unit (make sure that you call a qualified electrician if the disposer does not have a flex with a plug but needs to be wired in to your electrical system).

To help fine a new model, if you’re like me, you’ll hit the web and look for garbage disposal reviews, do plenty of research, talk to your friends and neighbors, and then find the lowest price for and buy the best waste disposer on the market.

The waste disposal units on this chart are only the most popular or highly rated disposers available on the market. There are literally hundreds and there’s no way we can list them all.

What is a Food Waste Disposer?

Garbage disposals or a food waste disposer is a compact, cylinder-shaped unit that fits under your kitchen sink (normally attaching straight onto the plug hole). The unit has a power electric motor that spins a grinding system that can chop up and grind food waste as it’s pushed into the sink’s plug hole.

Since a food waste disposer is normally attached directly to the bottom of the sink, the manufacturers have devised quick-fit ways of bolting the units under the drain and then connecting them to the trap in your sink’s plumbing. The disposer also needs to be wired in to the electric supply and to a switch (often mounted on the wall or in a special hole drilled into the sink) to control its operation.

The original models were incredibly noisy in use, making it hard to hear yourself think, let alone hold a conversation. The latest garbage disposers use nylon grinding chambers and have special insulation panels to reduce the noise considerably when grinding anything from corn cobs to chicken bones.

Best Garbage Disposal Cleaner – Avoid Jamming

It’s a very convenient alternative to just throwing food waste into the trash can – and get the right HP power rating and your disposal unit will grind up pretty much any food from chicken bones to corncobs. If you’re pushing through a lot of fatty food waste, you should also look to clean your disposal unit regularly using a good garbage disposal cleaner to remove the build-up and reduce potential odors. (If your unit has got clogged up or jammed, read our guides to help fix your problem.)

Plumbing And Your Connections To The Sewage System

In general, if your house is on a sewage system, then the ground food waste will be sent via your sewage pipes to the drain and the local municipal wastewater processing plant where it’s normally processed back into bio-solids that can be used as fertilizer or bio-fuel.

If your municipal district requires you to pre-process the waste, or if you are connected to a private cesspit or storage tank, then you should look at some of the specialist disposers that are designed to work in a more environmentally-friendly way and avoid blockages – they do this by starting the natural process of waste decomposition as soon as the food is ground down. These models include a separate tank connected to the disposal unit that injects bio culture into the food waste to help break it down as it moves through the sewage system.

Garbage Disposal Reviews – Find the Best Model

At the top of this page you’ll see the interactive chart I put together. It highlights the key features of different models. Use this as a starting point to either find a direct replacement for your existing unit or to choose the best upgraded model with a more powerful motor, or one that’s quieter in operation.

I’d recommend that you use the Comparison Guide above to help you make the right buying decision for your new disposal unit… but also look at the individual reviews of disposers on this site from manufacturers including Waste King, InSinkErator, Whirlpool and Whirlaway.

How Much Power Do You Need For Your Garbage?

When you’re buying a new disposal unit, there are some key factors to look out for. Read our guide to features for additional information to help you with your research. One of the main measures of any unit is the power of the motor (I list the power of each model in my comparison guide) which will help you choose a model that’s right for your level and type of garbage.

What horsepower garbage disposal should I get?

The standard measure for a disposal unit is horsepower (HP) that will give you an idea of the power of the electric motor inside the unit that chops and grinds the food. The greater the power, the greater the ability of the unit to cope with lots of use and bigger, harder items (like bones):

  • 0.50 horsepower garbage disposal: this and the smaller 0.30 horsepower units are designed for light use, normally designed to cope with the needs of an individual in a household.
  • 0.75 horsepower garbage disposals: these units are designed for typical family use.
  • 1.00 horsepower garbage disposals: these are heavy-duty units that are designed for large families and offices.

Type of Feed System: Continuous Feed vs Batch Feed

There are two main types of operating mode for disposers: continuous feed and batch feed. Each has its own benefits and problems – and there’s often a price difference between the two so before you buy, it’s worth being sure that you select the model with the feed system that you need for your installation.

What is a continuous feed garbage disposal?

Continuous feed is the most commonly used operating method – the unit needs to be switched on (this can be  automatically via a sensor or more commonly via a switch mounted on the sink or on the wall near the sink). And don’t forget you need to turn on the water when using the unit or the disposer will jam very quickly. Check out my list of the top ten continuous feed garbage disposal units.

What is a batch feed garbage disposal unit?

With a batch feed unit, you push food waste into the unit, then insert a plug into the plug hole switches on the motor in the unit which grinds the waste. This means that on a typical session after a meal you might ‘load’ the food disposer several times. Take a look at our guide to the best batch feed garbage disposal units.

Buying Decisions – Which Is The Best For Home Use?

I’ve written my reviews to provide good, helpful advice that will give you enough information to buy the best model for your needs. Whichever unit you decide on, you’ll find a good model will transform how you dispose of food waste, quiet, the right HP so it’s powerful enough and not too expensive.

If you’re planning on installing it yourself, the twist-on fittings of all the modern brands make it really easy – though you’d be advised to get an electrician in if it’s one of the few units that needs to be hard-wired rather than a normal electric plug.

Lastly, don’t forget the maintenance! I’ve looked at a range of products to help you prevent blockages – but if you are completely stuck take a look at my article on fixing a blocked disposal unit.
