The Best Garbage Disposal Option

Residential garbage disposals are not only great for post-meal cleanup, but they also reduce the amount of leftover food scraps in the trash can, which cuts down on odors. Plus, the typical garbage disposal will last 8 to 15 years.

All garbage disposal brands pulverize soft foods with ease, but some do tend to jam while trying to grind raw, fibrous vegetables, such as celery. On the other hand, some of the most powerful disposals will break down chicken bones!

Before You Buy a Garbage Disposal

Not all municipal sewage systems can handle food waste from garbage disposals. Since bits of food flow through the drain pipes, using a garbage disposal can increase the risk of clogs in a home’s plumbing, or possibly even cause problems in septic and municipal sewage systems.

  • Contact the local building authority to determine whether garbage disposals are permitted in the community.
  • If users experience frequent clogs in their home’s plumbing, they’re probably better off passing on a disposal, even if they’re permitted in the community.
  • Food particles break down slower than other types of waste, which can lead to accumulated food matter in a septic tank. If shoppers have a septic system, they will want to contact the company that installed it or the company that pumps out the tank and ask if their particular system can handle a disposal. Typically, larger tanks are more suitable for use with a disposal.
  • On average, 2 to 3 gallons of water per minute are used with a disposal. If buyers use their disposal twice a day, running it half a minute each time, they will use approximately 850 to 950 additional gallons of water per year.

What to Consider When Choosing a Garbage Disposal

Various factors go into choosing the best garbage disposals for a home. For example, the size of a family and whether shoppers have small children with curious hands can help them choose between a continuous-feed garbage disposal and a batch-feed disposal.

Family size can also determine power and unit size—based on the amount of food processed in a day. Finally, shoppers will want to determine if they will install the unit themselves or hire a pro. Knowing this can help them choose direct-wire versus a simple plug.

Continuous Feed vs. Batch Feed

A garbage disposal contains a motor and an internal canister, called a grinding chamber, which is fitted with sharp blades that spin at high speeds when the disposal is turned on. The bottom of the grinding chamber is perforated to allow pulverized food bits to flow out of the chamber and down the drainpipe. The two main garbage disposal types include a continuous feed and batch feed:

  • A continuous-feed garbage disposal runs continuously, allowing users to turn it on and put food waste in gradually while it’s operating. Most disposals on the market today are continuous feed and range in price depending on power and quality. The only major downside to continuous-feed garbage disposals is the possibility of hands getting in the grinder while it’s running, causing injury.
  • Batch-feed disposals grind food in small batches and are safer for families with inquisitive young children. A stopper must be securely in place before the disposal will operate. Safety is the main draw for batch-feed disposals, but they’re typically more expensive.

If buyers install a batch feed model, they’ll be able to run only one load of food waste at a time. The size of the grinding chamber will vary with the model but will typically grind 2 to 4 cups of food waste at one time.

Power

The more powerful the garbage disposal, the more efficiently it will grind food. Like nearly all appliances and tools with motors, the power generated by a garbage disposal is rated in horsepower, a unit of energy that was once compared to actual horses.

  • ⅓ hp: These are the most economical garbage disposals, but they tend to clog when grinding fibrous foods, such as celery or carrots. Unless shoppers plan to use the disposal infrequently and grind only soft foods, they’re better off with a more powerful model.
  • ½ hp: A ½-hp disposal is suitable for midsize households and will grind most food waste; just take care not to overstuff it to keep it from jamming.
  • ¾ hp: At this level, users will get some real power! A ¾-hp disposal can chew its way through fibrous foods without a glitch, and it is well suited to households with large families and substantial food waste.
  • 1 to 1⅕ hp: These powerhouses make quick work of grinding virtually all food waste thrown its way, including watermelon rinds.

Size

Greater horsepower requires a larger motor, which will often increase the size of the unit as well. While size varies widely by brand, the smallest ⅓-hp disposals range from 6 to 7 inches in diameter and 9 to 12 inches in height. By contrast, a 1-hp disposal can be up to 13 inches in diameter and 18 inches in height.

The only time unit size might make a difference is when shoppers have limited space under the kitchen sink. If they already have a water filtering system, such as a reverse-osmosis unit, they may not have enough room for a large disposal. Buyers will want to make sure to note the size of the units they’re interested in and compare them to measurements of the under-sink space.

Grinding Chamber Material

The grinding chamber is exposed to garbage and water much of the time, so shoppers will want to invest in a garbage disposal with a grinding chamber that can last for the long haul.

Grinding chambers are made from various materials, including stainless steel, plastic, pot metal, and galvanized steel. Each material has its pros and cons.

  • Stainless steel is the benchmark. Although it may cost a little more up front, it will also last longer—buyers may not ever need to replace the garbage disposal. In addition, the chamber won’t rust, and stainless steel grind components are the easiest to clean with ice cubes or rock salt.
  • Plastic comes in second as it won’t corrode. But the parts will eventually crack because the plastic will dry out. Even with that in mind, the parts will last a long time, and buyers should get years out of their plastic disposal. The lack of corrosion makes it simple to clean.
  • Pot metal will likely be plated or painted. Eventually, this coating will chip away, and the pot metal underneath will rust and be covered in a white powdery substance. However, even though they may end up looking bad, the thickness of the parts means they can last for decades.
  • Galvanized steel has a galvanized protective coating that starts to erode as soon as buyers start using the garbage disposal. In just a few months, the grinding chamber will rust, and in a few years, the parts may fail altogether.

Direct-Wired vs. Plug-In

Most garbage disposals do not come with power cords that plug into an outlet; they are designed to be wired directly into the home’s electrical system. A few models, however, come with cords and plugs that can be connected to an outlet beneath the sink. Models that do not have attached plugs can be converted to plug-in models with the purchase of optional plug-in cords, sold separately.

  • A cord that plugs into an outlet is the simplest to install, but a dangling cord beneath the sink can get in the way of stored cleaners and other items, which can dislodge the plug from the outlet.
  • Most professionally installed disposals are direct wired, which means the connecting wires are in a junction box in the wall, making it less likely that moisture will interfere with the wiring. A plug-in model could be affected by a water leak that runs down the wall, which could cause the outlet to short out and the circuit breaker to flip, although the possibility of that happening is unlikely.
  • While the choice to install either a direct-wired or plug-in disposal is usually left up to the buyer, it’s a good idea to check with the local building authority in case there are regulations in a particular community.

Connecting a plug to a nonplug unit is relatively easy if users have some wiring experience, and instructions come with both the disposal and with the cord kit. Hardwiring a disposal into the home’s electrical system is a much more complicated project and should be left to the pros.

Additional Features

Some additional features that shoppers can look for when purchasing a garbage disposal:

  • Anti-jamming: When too much food is packed into a disposal, the grinding blades can jam. Turning off the switch, removing the stuck food manually, and then pressing the reset button will usually fix the problem. Some newer disposals come with an anti-jamming feature that can detect a jam and automatically reverse the blades, which will often dislodge the jam.
  • Anti-splash: Splash guards keep the sink clean by ensuring that chewed-up food and water don’t make it back up into the sink. In some cases, it can even reduce the noise of the garbage disposal.
  • Corrosion protection: Corrosion protection inside the unit helps increase the lifespan of the garbage disposal.
  • Noise level: Loud operating noise has long been a downside to garbage disposals, but today’s models are much quieter, with the inclusion of insulation and padded mounts that reduce vibration. High-end disposals can be very quiet, emitting little more than a hum, while some budget-friendly models are still fairly loud.

Installation

Installing a new garbage disposal costs around $500. On top of the unit, the install will also require a new receptacle, fitting, switch, possibly some other parts, and the cost of time. Factor in about 1 to 2 hours of installation time. Replacing disposal units can cost as little as $150 for install and equipment.

For those planning to replace or install one on their own, a quick-mounting system allows for easy installation. The turn-and-lock system of the mount secures the garbage disposal to the sink. For those with recurring plumbing issues like backups or clogs, they may need to have the septic system enlarged or repaired first—this will add to the overall cost.

FAQs

For more information about the best garbage disposals, check out these answers to some of the most frequently asked questions. If additional concerns arise, contact the manufacturer.

Q. What horsepower garbage disposal should I get?

Garbage disposals are available in a variety of power levels ranging mostly from ⅓ to 1.2 horsepower. The higher the horsepower, the more food your garbage disposal is capable of grinding. Powerful models like the Waste Maid Premium Black 1¼ HP Garbage Disposal are ideal for larger households, or for those who plan on grinding tougher foods like watermelon rinds. Mid-range garbage disposals with ⅓ to ¾ horsepower top many “Best Of” lists (the InSinkErator Pro Series ¾ HP Food Waste Disposal is not only our Best Overall pick, but it also boasts some impressive Amazon reviews), just be sure to avoid overstuffing and tossing in fibrous foods like celery and carrots.

Q. Can you insulate a garbage disposal?

Yes. You can insulate the body of the garbage disposal with some soundproof materials. You can also purchase insulated units where the motor and the grinding chamber are covered in insulation materials on the inside.

Q. Are garbage disposals bad for plumbing?

Not if the garbage disposal is installed correctly, and you ensure your septic tank and municipal sewage can handle a garbage-disposal unit (contact your local building authority prior to buying). If your community gives you the green light for a garbage disposal but your house experiences frequently clogged pipes, you may want to consider a model with higher horsepower (like the Waste Maid Premium Black 1¼ HP Garbage Disposal) that is capable of grinding even the most fibrous and dense foods to a pulp.

Q. What can I clean my garbage disposal with?

Ice cubes, rock salt, vinegar, and baking soda—to find out more, check out this article about how to clean a garbage disposal.
