This is the Waste King 9980 review and we are going to look at some of the things that make it one of the best garbage disposals available.

This unit, unlike the others, has a 3-Bolt Mount when it comes to the installation part and can always be compared to the InSinkErator Evolution Excel. The waste king 9980 is a continuous feed garbage disposal unit with a 1.0 horsepower motor. This is also an upgrade of the waste king legend 9950. With that being said, let us now look at some of the features that this product has.

  • Grind components made of stainless steel
  • Lifetime corrosion warranty
  • 1.0 horsepower motor
  • Lifetime in-home service warranty

Waste King 9980 Installation Instructions

Unlike the other waste king legend products, this one has a 3-bolt sink mount system which can be a little bit difficult to install when you are alone and you are doing it for the first time. However, look at it on the bright side, the mount is usually stainless steel thus giving you a durable product that you can use for a longer period of time without thinking about its replacement. You can also refer to the manufacture’s manual for more instructions on how to install the unit. There are also some video tutorials on this which you can also watch to help you do the installation.

Lifetime Warranty

One advantage about this product is that it always comes with a lifetime warranty. I do believe that this is one of the features that makes the waste king legend 9980 to be among the best garbage disposal units on the market today. This means that when your unit suffers any material or mechanical defect during the time you will be using it, the company will come to your home and repair the damaged parts or just replace the whole unit.

1 Horsepower 2800 rpm Motor

It is usually said that this is the most powerful garbage disposal you can ever find in this range. With a 1.0 horsepower motor, this is the fastest motor for all the garbage disposals. The waste king legend 9980 garbage disposal has a motor that operates at a high speed of 2800 rpm and it also uses less power for its operation hence it is an energy efficient product. With this power and speed, this disposal can grind almost anything. It is also a continuous feed disposer which means that you can always add food waste continuously while it is in operation. This should include water too. The unit also has a sound insulated shell to prevent it from producing a loud sound when being used.

Another advantage of having a disposal with this type of motor is that it doesn't leave behind any debris. A lot of users usually fear for this which forces you to do a constant cleaning to remove the debris. With this kind of speed produced by the motor, all your worries will be taken care of since everything will be grinded even the onion skins which are usually known to block your sink. They will not only be grinded, they will also be liquefied and be disposed of.

Stainless steel grinding components

The waste king 9980 has many amazing features. One of them being, the fact that it has its grinding components made of stainless steel material. This means that it cannot be affected by rust. I tend to think that it is because of this that the company is happy to provide the customers with a lifetime corrosion warranty. The steel grinders are always efficient and durable and this enables you to dispose of any type of food in the sink. Even the shredder ring and the swivel impeller are both made of steel.

Noise Level

The waste king legend 9980 usually produces a relatively quiet sound when being used. However, I cannot say that it’s that much silent. Even with the sound insulation shell, it is still noisy. Well, the noise is usually at some reasonable level but you need to put in mind that this is a garbage disposal that can grind the tough foods and even small bones. With this, you can be sure to hear some sound emanating from the unit and the sound level increases when grinding a greater amount of food waste in the disposer or when the food waste is a bit difficult to grind. You can even hear some loud click when the motor starts up. This alone can be annoying to some noise sensitive users.

Pros and Cons of Waste King 9980


  • It has an easy installation which one can do by himself
  • It has a 3 bolt connection that results in a tight fit between the sink and the disposer
  • The unit comes with an installation guide which is always easy to understand
  • It has a pocket-friendly price


  • For those having cast iron sinks which might be having a foreign design, it is advisable that you look for some adaptor in order for your unit to fit correctly
  • The unit produces a relatively loud and clanking noise when the motor first engages and this can be annoying to other users


Waste king 9980 might not necessarily be the best garbage disposal but for sure it is rated to be among the best garbage disposal around. This is the kind of product that will always suit those users who prefer to save some cash by purchasing a quality product at a relatively cheaper price.

However, I can say that you must be ready to adjust to the noise level produced by this disposal when being used. This product even though it has a powerful grinder, it is still prone to clogging occasionally. It also has a small size which can perfectly fit under your sink, saving you some space.
