Buyer’s Guide

Before buying a garbage disposal to get rid of your food waste, it’s important to consider how its specifications impact its performance. Here are three factors to think about when purchasing a disposal.

Dimensions

A garbage disposal’s dimensions impact its compatibility with your kitchen sink. For example, larger models might not fit in the cabinet under your sink. While purchasing a compact garbage disposal removes the hassle of fitting the model under your sink, most compact garbage disposals sacrifice power for size.

Horsepower

A garbage disposal’s horsepower influences the type of food it’s able to grind. For example, a 0.25-horsepower disposal can tackle meat trimmings and other soft food, while a 0.75- or one-horsepower disposal can grind tougher particles, such as melon rinds.

Grinding Technology

Garbage disposals are split into two different types: continuous-feed and batch-feed models. Continuous-feed disposals run continuously once their power is turned on, making it easy for users to throw large amounts of food into their grind chambers. Most batch-feed garbage disposals run only when their drain covers are in place, limiting the amount of food that can be ground at once.

Material

Most residential garbage disposals have a grinding chamber that’s made from either stainless steel or galvanized steel. If you can afford the extra cost, we recommend stainless steel grind components because they are more resistant to corrosion and rust. While galvanized steel has a rust-resistant coating, the metal starts to rust as soon as this coating chips in one place. You’ll also find plastic grinding chambers. Though affordable and corrosion-resistant, plastic eventually cracks.


Garbage Disposal Dos and Don’ts

A backed-up garbage disposal can turn an already cumbersome meal cleanup into a nightmare. To get the most use out of your new disposal, check out what to do—and what not to do—below.

Dos

  • Do keep your garbage disposal clean.
  • Do run your disposal regularly, as this prevents rust and corrosion.
  • Do cut or tear large food particles into smaller pieces before loading them into the disposal.

Don’ts

  • Don’t put the following items down your garbage disposal:
  • Fibrous vegetables
  • Fruit pits
  • Oils, fats, and other fluids that congeal
  • Bones
  • Anything that’s not food
  • Don’t overload your disposal by putting too much food down it at one time.
  • Don’t stick your hand down the disposal to remove a jammed item without turning off the power first.

Frequently Asked Questions

How does a garbage disposal work?

You mount the garbage disposal to the underside of your kitchen sink to catch solid food as it enters the drain. Once the food is in the disposal’s grinding chamber, you can turn on the device to grind the food into small particles. These particles easily pass through your plumbing pipes instead of causing clogs.

How long do garbage disposals last?

Most garbage disposals last around 10 years. If your model has difficulty grinding food, makes a louder-than-usual noise, or frequently clogs, it might be time for a replacement.

How do I use a garbage disposal?

Run cold water in your sink before turning the disposal on. Once the device is on, gradually drop food into the drain. When you’ve finished disposing of the food, turn off the device. Leave the water on for a few more seconds to flush your pipes.

Do I need a professional to install my garbage disposal?

Though many garbage disposal manufacturers promise easy installation, we recommend consulting a plumber if you’re not particularly handy. You don’t want to install the disposal improperly, as this can lead to leaks.

How do I clean my garbage disposal?

To clean a garbage disposal, pour ice, lemon juice, or vinegar down the drain to clean the device naturally. You can also find a variety of cleaning products on the market that unclog and freshen garbage disposals.
