How to Choose the Right Garbage Disposal

A garbage disposal helps reduce landfill waste and keeps your home smelling fresh between trash days. Not all disposals are the same, so choosing the right one depends on multiple factors. This master guide will walk you through the options so you can pick the best garbage disposal for your kitchen, whether you’re replacing an old unit or installing one for the first time.

Types of Garbage Disposals: Continuous Feed vs. Batch Feed

Garbage disposals come in two feed types: batch feed and continuous feed.

Batch feed: Only works when you place a special magnetic stopper into the opening. This safety feature prevents objects from accidentally falling when in use. With this type, you can insert food waste in batches and grind it all at one time. A batch feed garbage is a good choice if adding a wall switch isn’t possible.

Continuous feed: Runs as long as the power is on, so you can keep adding food scraps as you clean up. They’re usually controlled by a wall switch, sink-top switch activator or power outlet below the countertop. This type is the most popular for homes because it’s faster and more convenient for everyday use.

Horsepower Ratings

Garbage disposal motors come in varying horsepower (HP) ratings, anywhere from 1/3 HP to 1 HP or even higher. Horsepower determines how much a disposal can grind. 

Here is a breakdown of common HP ratings and their capabilities.

  • 1/3 HP: Best for small households (up to two people). Recommended for light-duty jobs.
  • 1/2 HP: Ideal for light to regular use in homes of two to four people.
  • 5/8 – 3/4 HP: Handles medium-duty jobs for homes with three to five people.
  • 1 – 1 and 1/4 HP: Ideal for larger households (over 4 people). Can handle heavy use.

Please note: Garbage disposals with more horsepower are often quieter and less likely to jam compared to lower horsepower models.

Smart Features to Consider

  • Sink-Top Switch: Sold separately, this switch uses air pressure, alternative to a wall switch. Works with a continuous-feed garbage disposal. An ideal switch solution for kitchen islands because you don’t need to hardwire it to a wall switch.
  • Power Cord: Power cords are included with your machine or sold separately. You’ll need a cord if you plan to plug the disposal into an outlet. 
  • Auto-Reverse: A feature that automatically spins the grind table in the opposite direction to help prevent jams if food gets stuck.
  • Stainless Steel Parts: Disposals with grind chambers and components made of stainless steel often last longer.
  • Quick-Mount Feature: Uses a turn-and-lock system to secure the disposer to the sink, making installation easier.
  • Baffle: This rubber guard is installed at the sink opening and keeps food and water from splashing out of the grind chamber.
  • Multiple Grind Stages: Basic models include only one grind stage. Premium models can have up to three separate stages to fully break down food so it washes down the drain easily.
  • Quiet Models: Designed with sound-reducing features such as insulation, sound baffles and flexible mounts to reduce excess vibration and noise.

FAQs

1. Are garbage disposals safe for septic systems? 

Yes. There are disposals specifically designed for homes with a septic tank. During use, these models spray an enzyme to help further break down food waste as it enters your septic system.

2. Can I grind bones and fibrous vegetables? 

Sometimes. Higher-powered units can handle tougher scraps and even some bones, but it’s generally recommended to avoid putting very hard items to prevent damage and jams.

3. Are stainless steel parts really better? 

Yes. Stainless steel grinding chambers and components resist rust and corrosion, extend the life of the disposal, and help with quieter operation compared to cheaper metal parts.

4. Is a garbage disposal right for my kitchen?

Check local codes to determine if disposals are allowed in your area. Make sure your plumbing is in good working order before purchasing a disposal. If your pipes are prone to clogs, address the cause of the problem during or before installation.

5. How do I maintain my garbage disposal?

Regularly flush with cold water while running, avoid putting grease or fibrous materials down the drain, and occasionally grind small citrus peels or ice cubes to clean and sharpen blades. Follow manufacturer care instructions for best results.
