Waste King 9980Waste King 9980 Legend Series 1 HP Garbage Disposal Review

If you work around the kitchen often, whether it’s cooking, baking, or grilling, having a garbage disposal is going to making cleaning up much more tolerable. Being able to funnel all of your food waste and left overs into a garbage disposal instead of needing to make multiple trips to the trash can, where the food will begin to rot and smell up the kitchen, is not only easier, it’s hygienic.

Waste King has an incredible line of high-end garbage disposal called the Legend Series. The 9980 model is the perfect choice for people who do like to cook, bake, and grill often as it can handle large loads of food waste easily and often with its 1 HP motor. Backed by WK’s lifetime warranty, it’s hard to find a better option.

Motor Power & Performance

The Waste King 9980 garbage disposal features a 1 HP, 2,800 RPM permanent magnet motor which will make very quick work of even very tough food waste like chicken bones or artichokes. If you have a large family or you just like to cook on a regular basis, getting a high horsepower disposer is going to be important. A higher horsepower garbage disposal will better suit a large family since it can handle large amounts of food waste in seconds which in turn will prolong the life of the unit.

Feed Type

The WK 9980 model is a continuous feed disposal which means you can continuously funnel leftovers, egg shells, potato peels and fruit rinds down into the garbage disposal until everything has been cleared away. This is much more convenient, and usually cheaper, than a batch feed model which requires you to grind up food waste in batches since a cover must be attached during the grinding process. Because of this, continuous feed disposers are more popular since they take less effort and less time to operate.

Materials & Components

As with every unit in the Waste King Legend series, the 9980 model is made with glass-filled nylon grinding chamber and stainless steel grinding components which all prolong the life and usage of the unit since they are resistant to corrosion and rust. For anyone who has owned a low-grade or basic model garbage disposal, you know that corrosion can quickly end the life of the disposer which may not make it to 4 or 5 years.

No one should have to continually keep replacing their garbage disposer every few years, and Waste King has considered this. You can be ensured that when you buy a WK product, you are getting an appliance that will typically outlast every other garbage disposal on the market. Plus, the fact that WK offers a lifetime warranty on this product only adds to the fact that they are committed to producing excellent quality disposers.


Most everyone has commented on how quiet the Waste King Legend 9980 runs compared to the model that they replaced. The only sound people noticed that seemed to bother a few people was a quick click when you turn the unit on. This disappears immediately as it continues to run and begin to grind up food. Most people were not deterred by this clicking sound and mentioned it was quite normal to hear.

Over all, the unit runs quietly thanks to the sound insulation that WK uses in the Legend series. You’ll easily be able to carry on a conversation with people in the same room, no need to raise your voices to hear each other.


The biggest difference with the Legend 9980 versus the Legend 8000 is the installation process. The 8000 uses the EZ Mount system whereas the 9980 uses the 3-bolt mount system. The 3 bolt mounting system features all stainless steel mounting components and can be an easy replacement for older models which utilize a 3 bolt mount system since it simply just slides in place to be bolted to the sink.

On the other hand, an EZ Mount system is generally better for first time garbage disposal installs, or if you replaced everything including the sink flange of your last garbage disposal. If you currently have a 3 bolt mount system and would purchase an EZ Mount disposal, you would need to purchase a conversion kit to get the disposer to fit. If this is the case, you might as well purchase a unit that already features the 3 bolt mounting system so you can save yourself time and money.

Dimensions & Capacity

The WK 9980 is 16 1/16 in. tall and 8 ½ in. in width. It will fit fine under standard sized cabinets and sinks with no problem. People have even mentioned that the unit fit nicely in the smaller portion of a double sink.


If you want to own a reliable garbage disposal that will do what it’s supposed to, when it’s supposed to, purchasing a Waste King unit will ensure you get what you desire. With 60 years in the business, WK knows how to produce quality products. Here’s a look at the specs and features for the Waste King Legend 9980:

Horsepower: 1 HP
Motor: 2,800 RPM
Power Cord: 36” power cord included
Feed: Continuous Feed
Operation Requirements: 115 Volts, 60 Hertz, 6 Amps
Septic System Safe: Yes
Warranty: Lifetime Manufacturer Warranty with In-Home Service


If you intend to grind a lot of bones, raw vegetables, coffee grinds or other tough foods, investing in a high horsepower garbage disposal is essential. 1 HP is one of the highest HP you can get for a non-commercial unit which means you get a ton of power to make quick work of those left over buffalo wing bones, pineapple rinds, and even vegetables like artichokes.

Because the food waste gets pulverized into tiny particles, this unit will be safe for properly-sized septic systems and tanks. Even though many people think you can’t use a disposer in conjunction with a septic system, this is untrue if you get a quality garbage disposal.

What’s Included

In the box, you will find the Waste King Legend 9980 garbage disposal, 36” power cord, and easy-to-read and follow installation instructions.

Optional Accessories

While the Waste King Legend 9980 disposal will work perfectly on its own, there is a cool set of accessories you can purchase if you’d like to control the unit without needing to hardwire it into your electrical system. The Fiber Optic Remote Switch can install into your second sink hole (for soap dispenser) if you have one, or you can drill a hole to easily install this switch which will allow for sink top operation with no hard wiring necessary. You can also order the Waste King 3140 Extended 3-Bolt Mount Sink Flange if you have an extra deep sink and need to extend the flange to make it accommodate your new disposal.


The 1 HP 9980 unit is top-of-the-line when it comes to Waste Kings Legend series. The high horsepower and high RPM will grind even tough food in literally seconds which will conserve water and electricity, not to mention extend the life and usage of your disposer.

Also, the 3 bolt mount system is perfect for replacing older 3 bolt mounted models. Installation can take less than an hour and that hardest part will be removing your old unit which can prove difficult due to corroded screws or bolts. You can easily install this unit on your own and save tons of time and money since you won’t have to hire a professional.

Finally, one of the best things about owning a Waste King is having one of the best warranties on the market. This particular model features a lifetime warranty which provides great assurance that you’ve made a really good investment.


It was hard to find anything negative about the Legend 9980. The biggest complaint that I’ve seen is that the unit can make a loud click when it first turns on, but after the initial click the unit practically purrs with quiet operation. It only seemed to bother a few people, but it was worth noting. If you are looking for the same unit only with a EZ Mount system check out my Waste King L-8000 Review here.


Consumer Reviews

The Waste King Legend 9980 has scored quite well with customers. Just under 75% of customers gave this unit a perfect score calling it things like “the Pit Bull of garbage disposals” and “top of the line”. Only 6% of customers felt that it operated at less than average standards. You can be certain that if you invest in this model, you are getting a quality product that will probably outlast how long you live at your current address.

Even though the Legend 9980 is a heavy-duty 1 HP garbage disposal, it is still quite reasonably priced compared to competition. The warranty itself makes the entire product worth it. Why buy a number of cheaper disposers over the span of 20 years when you can purchase just one that will last just as long if not longer than 20 years for just a little bit more than one cheaper disposer would cost. Every time I check, Amazon constantly has the lowest price for this model.
