Waste King 9920 Garbage Disposal Review

Average Customer Rating: 4.4 out of 5

Rating: ★★★★½ 

The Waste King 9920 Legend Series is a cheap garbage disposal but that does not mean that it is poor product. On the contrary, you get very good value for your money. The Waste King 9920 is a compact but relatively powerful garbage disposal.

If you have a lot of tough food waste, you probably need a more powerful garbage disposer than the 0.5 HP 9920. But for smaller households with normal food waste it is a good solution. If don’t have much space under the sink, the compact design of the Waste King 9920 may be exactly what you need.

Like the other garbage disposers in the Waste King Legend Series, the 9920 is easy to install, no special tools or skills are necessary but a little bit of silicone, which is better than plumber’s putty, may be useful. The Waste King 9920 uses the 3 Bolt mounting system. If you prefer the EZ mounting system, the compact Waste King L-1001 may be the best garbage disposer for you. Here you can learn more about the Waste King L-1001.

The Waste King 9920 is relatively quiet and has no trouble grinding all normal food waste. But as mentioned earlier, it is a 0.5 HP garbage disposal, so it is not as fast and powerful as the more expensive high-end models.

You will not have any problems with rust. The grinding chamber is made of glass-filled polyester, it has proven to be a very tough material. The swivel impellers are made of stainless steel.

The Waste King 9920 is backed by a 2 year In-Home-Service warranty, meaning that a defect unit will be replaced in your home free of charge. You get a 36 inch power cord and removable splash guard with the 9920 garbage disposer. It is possible to connect a dish washer to it and it is safe to use with properly sized septic tanks.

One potential drawback is that jams must be cleared from above, using for example the handle of a wooden spoon. There is no hole at the bottom of the garbage disposal to clean jams using an Allen wrench. But as long as you pay attention to what you put into the 9920, jams should not happen.


  • Space saving compact design
  • Very good value for the money
  • Quiet


  • Jams may be difficult to clear
