Waste King L-8000 vs InSinkErator Evolution Excel: Appearance

Most garbage disposals will look rather similar. Considering it will go under your sink and hardly ever seen, it’s not worth choosing one based on color or looks. A 1 HP garbage disposal can weigh anywhere from 15 to 30 pounds. While the size will affect your storage space, the weight will play a part in the installation.

Waste King L-8000

This is a great sized garbage disposal at 8.5 x 7.5 x 16 inches, this compact design will leave more space in your cupboard. It weighs just 11.94lbs, which will make installation a lot easier. It also comes with a 32-inch power cord.

Waste King L-8000 Size

It is quite a bit larger at 13 x 12 x 12 inches. It weighs 20lbs so you might need an extra pair of hands when installing it. Unfortunately, there is no power cord supplied.

The Winner is – The L-8000

Waste King L-8000 Review

With 1 HP, your garbage disposal should be powerful enough to quickly grind vegetables, peelings, meat, poultry, fish, and small bones. The RPM for a 1 HP garbage disposal is from 1725 to 2800.

Waste King L-8000

With a high RPM of 2800, it will have no trouble grinding typical waste. It also has a permanent magnet motor enabling it to reach full speed almost instantly. This reduces potential jams. There is an automatic shut off in case of a jam and an easy access manual rest button.

InSinkErator Evolution Excel

While it only has 1725 RPM, it does have other advantages. There is multi-grind technology with 3 levels of grinding. It has a Jam Sensor Circuit that will automatically increase the torque by 500% for tough jams. If a jam is imminent, the auto-reverse grind system will kick in and reverse the direction of the grind. The manual reset button is underneath, so not as convenient as the L-8000

  • It’s incredibly quiet, even when grinding harder garbage
  • Excellent customer service from people who actually know about the product

InSinkErator Evolution Excel


  • The quality of the materials is superb
  • High-quality engineering with the 3-layer grinding, no problem with small bones
  • Even though it’s heavy, it is still easy to install
  • It’s so quiet you may think it isn’t working


  • It’s bizarre to spend so much money and not have a power cord with it
  • Your sink may drain a bit slower

The Final Verdict

As you can see from the section on their differences, it’s a close call between the Waste King L-8000 vs InSinkErator Evolution Excel. In terms of appearance, ease of use and value for money, the Waste King L-8000 comes out on top. For materials and grinding capability, it was the InSinkErator.

When we tried to install these garbage disposals we noticed that the InSinkErator was easy to install if you were replacing an older InSinkErator model, it wasn’t as simple if not. We are still baffled as to the lack of power cord.

Both models have the same power motor however the L-8000 has a higher RPM. While testing the two with various types of waste we noticed very little difference in their abilities. On this subject, please be wary of the reviews you read. Garbage disposal is designed to grind waste from your plates. This waste should already be in small pieces. Any garbage disposal is going to have issues when you try and stick a whole piece of broccoli down it!

Both models were also very quiet, but if we had to choose a winner, the InSinkErator is slightly quieter. There are no points for this, but we do love the originality of the brand name.

The overall winner is the Waste King L-8000. It is an excellent machine that does a great job in busy household kitchens. It is quiet, lightweight and powerful. The 20-year warranty shows just how much faith Waste King has in its products. We couldn’t find any reason to justify spending more than double the cost of the L-8000 for a garbage disposal that doesn’t equally outdo it. If you are someone who appreciates good customer service, you will be glad you chose the Waste King L-8000.
