Buyer’s Guide

Before buying a garbage disposal, 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.

Frequently Asked Questions

How does a garbage disposal work?

Garbage disposals are mounted 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, users can turn on the device and grind the collected 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 you use a garbage disposal?

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