No products found.

Let me start with the words, “low-priced and capable”. Waste King L-9930 is a good choice as it is a very affordable for a kitchen garbage disposal, with a medium range power. It can be great for a small family.

The reasons you can consider to buy the Waste King L-9930 are; its efficiency, price, and warranty. Also, if you prefer the 3-bolt mounting over the EZ Mounting system, then it is the perfect disposal for you as well. There’s nothing fancy about this unit in particular, but considering its price, it will get the job done.

That being said, you’ll be interested if you have a low budget and want a medium range disposer with an average period of warranty time.

  • Best For Small Family

Waste King L-9930 is a continuous feed kitchen garbage disposal with a ½ horsepower vortex permanent magnet motor that runs at a speed of 2600 rpm.

It can fairly easily grind whatever kitchen waste you throw in it. As long as you don’t start throwing a high amount of hard food wastage all at once, you won’t be dissatisfied with the performance.

Nevertheless, you must consider that it won’t be as efficient as an expensive 1 horsepower motor kitchen garbage disposal unit. I would like to point out that I am suggesting this as a good device for small families who require disposing a usual amount of food from their kitchen.


Waste King L-9930 has a 3 bolt mounting system, so it will be super easy to replace with an old 3 bolt mounting system.

Many users replace their old InSinkerator Badger disposals with this one just using some extra plumber putty on the Waste King flange.

As a result, you can even replace it with an old EZ Mounting system, without purchasing any expensive tools for it. As a first step, you need to change and swap the mounting, as all elements for installation are already provided.

The instruction manual is quite detailed and self-explanatory. Therefore, I would suggest to follow carefully all the steps in the manual. People who have no or very little experience with plumbing can also install it without any issues. Check the best price at Amazon.

Perhaps the most noteworthy fact is that this kitchen garbage disposal has a corrosion proof glass filled polyester grinding chamber with stainless steel swivel impellers. Also, it works great for a regular sized septic tank. The rubber safety guard keeps stuff from falling down inside the unit.


As compared to other garbage disposal units, this particular garbage disposal unit might not be the best solution for buyers who are not fans of high noise level coming from their disposals. But many also say that Waste King L-9930 is much quieter than the usual old models from other disposal brands. 

Yes, you will be hearing some grinding sounds when you are working with it, but that noise will not be loud enough to particularly disturb you. If you are looking for the most silent kitchen garbage disposal it may not be a good choice for you.

Weight & Size

When it comes down to weight & size, you'll need a reasonable enough space to put it under the sink. It has a dimension of 9 x 9 x 14.3 inches with 10.2 pounds of weight.


You get 5 years mechanical In Home warranty and a lifetime corrosion warranty for this device.

Pros & Cons


  • Powerful but Light weight
  • Easy Installation with already included components
  • Stainless Steel Corrosion Proof internal elements
  • Rustproof Stainless Steel swivel impellers
  • Perfect for a budget concerned buyer


  • The noise is a pretty negative issue for few consumers, although many say it is not that loud compared to old badger models.
  • Unlike the other high-end Waste King garbage disposals, the splash guards are not removable.
  • The size of this disposer is bigger than the others available in the market. So, before purchasing you must check if you have enough room for it under the sink.
  • As the opening of the disposal is small like many of Waste King Garbage Disposals it has an issue of running the water slower than usual. In terms of that, it works a bit slower comparing with other disposals.

In conclusion, Waste King L-9930 Garbage Disposal get higher specifications and power at the same price comparing to the other models. It may not be that quiet, but it is fast and powerful to chew up your kitchen mess.

In general, I’d recommend this kitchen garbage disposal simply because, within a marginal price (check the best price at amazon) you get a powerful corrosion proof disposal unit, all the equipment for an easy installation and a great warranty. Therefore, I can suggest it as one of the best garbage disposals within low budget. Check the actual price here!

There is another Waste King garbage disposal containing exact same features as L-9930. Both of these disposers are equal in terms of power, speed and warranty. The only difference between these devices are the mountings.

Where L-9980 has a 3-bolt mounting, Waste King 2600 contains EZ Mounting system. In terms of price, you need to spend 10 more bucks if you want to get the L-9930 model. Although L-2600 is a more popular sink garbage disposal than this one. Due to this fact, many of you will now consider checking out the Waste King L-2600, but those who are more comfortable with 3-bolt mounting; my preference for them is Waste King L-9930.
