Waste King Garbage Disposals Reviewed For Home Use

Find which Waste King model is best suited to your food disposing needs.

A good garbage disposal adds value to your kitchen and makes cleanup a breeze. Whether you’re a home chef extraordinaire or only make the occasional at home meal, you can benefit from using a garbage disposal to manage your food waste needs.

A garbage disposal installs under the kitchen sink and connects into the outgoing pipes you already have under the sink. With this installation, you can just slip scraps from plates and pots right into the disposal where they get ground up into tiny pieces.

Garbage disposals are not only convenient for disposing of food scraps and waste, but they’re environmentally-friendly, as well. Disposing of food waste breaks components down into a near-liquid state. The resulting slurry is much easier than intact food scraps are to process through municipal waste systems.

Using a garbage disposal is simple. Operation generally involves filling the disposal with scraps and flicking a switch to run. Even food scraps from the dishwasher automatically load into the unit, saving you time when cleaning.​

Choosing a garbage disposal unit for your home can be daunting, and I’m here to help. In this guide, we’ll look at a collection of Waste King garbage disposals to find one perfect for your setting.

How to Choose The Right Waste King Garbage Disposal Unit?

Waste King leads the pack in the garbage disposal industry. And while all of their machines are sure to do an excellent job in your kitchen, you need to pick one that best aligns with your needs.

Here are all of the things you need to consider when planning a garbage disposal purchase:

How much power do you need?

Depending on your food waste volume and frequency of use, you will need to determine the power level you desire from your garbage disposal. Most garbage disposal units come in motor power sizes from 1/4 HP to 1 HP.

Obviously, the greater the power, the more grinding and shredding capability the disposal can offer. Individuals who do not do much food prep and only feed one to two people per meal can benefit from smaller disposals. On the other hand, proficient home chefs and large families can make good use of a higher powered, 1 HP or greater machine.

Are garbage disposals allowed in your location?

​Some cities and municipalities do not allow residents to use garbage disposals within city/town limits. If you live in an area like this, you will not be able to purchase and install a home garbage disposal unit.

Do some research to learn whether your location allows garbage disposals. If you rent, you also need to ensure that your landlord will approve the installation.

Do you use a septic system?

Septic system users need to pay extra attention to whether they can safely incorporate a garbage disposal into their kitchen. Because disposal waste joins the home’s main output lines, the septic system is impacted by garbage disposal use.​

Many disposals are rated for safe use with septic systems, though some are not. Septic system users must take special care to check disposal ratings for this detail. Additionally, there are softeners that can be used to make garbage disposal safe for septic use.

What is your budget?

Garbage disposals run the gamut of prices from low end (around $50) to high (up to $400). Waste King garbage disposals are priced to sell, and you will get the best bang for your buck when you choose one of these units.

In general, you get what you pay for when it comes to garbage disposal units. Lower powered units are less expensive than ones that edge closer to the 1 HP mark.

Lower quality units may be more noisy than their more expensive counterparts, which may be a consideration if you’re looking for a quieter model.


Other Considerations

Though I’ve outlined the main items you need to keep in mind before purchasing a garbage disposal, here are some more aspects to bear in mind:

Would a batch feed system work for you?

Most garbage disposals, including the ones listed here are continuous feed, which work continuously until you turn them off. However, batch feed systems are an option if you’re worried about exposed blades.

How noisy do you want your disposal to be?

Some users don’t mind the noise from a garbage disposal at work. Others prefer a quieter insulated model.

Are you installing it yourself?

Many garbage disposals come with instructions for easy installation, but some homeowners prefer to leave the work to a plumber. Deciding which option is best for you will help to inform your final purchasing decision. 

What type of food waste does your household throw away?

You should be thinking about the amount of food your family throws away when choosing a garbage disposal for your kitchen. Disposals perform differently based on their horsepower, feed system, and overall quality.

If you foresee yourself using your disposal frequently and throwing away lots, you should go with one that is of the highest quality and has a high-speed motor of at least ¾ horsepower (1 HP is even better).

Not only should you consider how frequently you'll be using the disposal system, but also the types of food you'll be disposing of. If you get rid of a lot of liquid-based foods a powerful motor does not need to be your primary concern.

For more solid foods like fruit or veggie or meat scraps, power is a crucial factor. You might also consider getting one with a 2 or 3-stage grinding system where the food is liquified before being sent down the drain.

This inforgraphic by waste king helps people understand which products are best suited to their needs.

Who Needs a Garbage Disposal?

Almost anyone with a kitchen sink can benefit from the purchase of an in-home garbage disposal. If you own your home and do not live in an area where garbage disposals are not permitted, then you should definitely consider making the investment in one of these units.

For starters, garbage disposals provide a somewhat messy - but necessary - cleaning function for food waste scraps in your kitchen. Whether you frequently cook at home or have your favorite carry out joints on speed dial, you can still find use for a garbage disposal.

Vegetable scraps, plate scrapings and old leftovers are all easily taken care of by a best garbage disposal. Even users who plan on using their disposal units once or twice a week will enjoy having a smaller 1/3 to 1/2 unit on hand.

Additionally, a garbage disposal is an easy way to make your home a little bit greener. This environmentally-friendly appliance gives you the opportunity to dispose of your food waste in the greenest way possible.

Disposing of food in a liquefied state, rather than as solids, allows it to be collected in a fashion which requires less energy. And smaller components are more easily biodegraded or sorted through than are hard scraps.


Why Choose Waste King?

Some reviewers claim that no kitchen is complete without a Waste King disposal system, and here’s why:

  • Waste King features a fast and easy mounting system for quick installation
  • WK offers the most extended in-home warranty in the garbage disposal industry
  • Each unit has a removable splash guard to aid with an internal inspection
  • They have a higher RPM on average than other brands
  • They use only the highest quality stainless steel resistant to corrosion
  • Every unit is septic safe and environmentally-friendly

In addition to these unique features, Waste King is an affordable option that fits into anyone's budget. This company has been providing its customers with quality garbage disposals for over 50 years, so they have had plenty of time to perfect their systems.


How does a Waste King Grinder Work?

This depends on the unit you choose, specifically if you go with a batch-feed or continuous-feed system. Generally speaking though, a WK disposal operates with an electric motor to chew up food scraps. It is mounted on the underside of the sink and plugged into a 120-volt box with a power cord.

Inside the unit, there is a grinding chamber where the food scraps enter and are shredded by the stainless steel blades. Once the shredding is complete, the food is pushed by an impeller arm down the drain with the help of a forceful stream of water. Water from the dishwasher drain also helps to drive any large food particles through.

The specific steps involved in the grinding process depend on batch vs. continuous feed systems. A continuous feed is activated by turning a switch on, and the disposal will not stop until the switch is turned off. Batch-Feed disposal is activated by filling the chamber first followed by plugging the sink drain.


Grinding Stages

There are several ways for a disposal to go about grinding up your food waste. Disposals feature either a 1, 2, or three-stage grinding system to get the job done. The cheapest (and least efficient) disposals have one stage of grinding before the food is moved through the drain pipe.

Wayfair says that a more efficient disposal system has a 2-stage grinding system. According to the leading home goods supplier, a disposal like this “grinds food in two stages to achieve a finer grind. The second stage of grinding virtually liquefies food waste, allowing for more types of difficult foods to be ground. It also decreases the chances for clogs or jams.”

There is also the option for a disposal unit with three grinding stages, but this is much less common. 3-stage systems have the most exceptional grinding capabilities on the market. You can grind pretty much any food waste, including waste that has to be avoided in 1 or 2 stage systems. It even has the ability to grind fibrous foods or harder materials.


Replacing or Installing a Waste King Disposal Unit

Since installing a garbage disposal requires a bit of electrical work, the job can be potentially hazardous. This might lead you to hire a plumber, but as long as you turn the kitchen breaker off and unplug the existing unit, you should be fine to do it on your own. Every Waste King unit comes with a detailed list of instructions and all the required hardware for proper installation.

Waste King uses a 3-bolt EZ mounting system that makes the installation process entirely hassle-free. Not only is the initial installable simple, replacing your Waste King with another model from the manufacturer is even more comfortable. This Waste King installation guide goes through each step in detail. 


Frequently Asked Questions

What is the best feature of Waste King garbage disposals?

Aside from the quality materials and effective grinding system, Waste King is praised for having the best warranty coverage in the industry. Most disposals, including InSinkErators, have a 1 to 3-year limited warranty. Waste King goes above and beyond by offering several models with a limited lifetime warranty for residential customers.

Is there a limit to the kind of food waste that we can put down the garbage disposal?

  • Fibrous foods (e.g., celery)
  • Chicken Bones
  • Fruit pits
  • Grease
  • Large quantities of rice or pasta
What should I do if my Waste King garbage disposal smells?

Getting rid of garbage disposal odor is best achieved by grinding up lemon peels or the peels of another citrus fruit.
