​Compare  Best Home Garbage Disposals: Waste King L-3200 vs. InSinkErator Evolution Essential XTR

InSinkErator Evolution Essential XTR Garbage DisposerInSinkErator Evolution (Photo Credits: InSinkErator)
A  home garbage disposal unit is an electrically powered device installed under the kitchen sink and that is capable of pulverizing or liquefying food waste, so it can be discarded through the plumbing.

Aside from offering practical convenience, garbage disposing units  provide an environmentally sound "green" solution to the growing problem of food waste as they eliminate transporting it to landfills, and they help reduce greenhouse gas emissions.  

​Furthermore, at capable waste-water treatment plants, food waste can be recycled to produce renewable energy.

Food Waste Disposal ProcessFood Waste Disposal Process
When considering to get one, the following points should be kept in mind:
  • It should be well insulated against noise.
  • ​It should support continuous feed rather than  batch feed.  Continuous disposal means that you can keep adding waste while the unit runs.
  • It should have a non-corrosive grind-chamber designed for long term durability.
  • It should be equipped with powerful grinding technology so the  food waste is quickly treated.

Note that top brands allow you to pulverize or liquefy various foods such as celery, small bones, corncobs, banana peels, apple cores, potato peels,  coffee grounds and more. Proper use of these units require avoiding grinding large amounts of these foods all at once and remembering to use cold water while operating the disposer.

The following table compares the various features that come with the two garbage disposal systems  (please read the explanations to the table notes that follow for a better understanding of the features):
Home Garbage Disposal Systems Comparison Table
Table Notes 1 - 10 Explained:

Note 1:
RPM = Revolutions Per Minute.  

Note 2:
Continuous disposal means that you can keep adding waste while the unit runs.
​
Note 3:
Most garbage disposal units come equipped with a single grinding stage which breaks and pulverizes the food waste into small particles, so it can easily  flow into your sewage system. Waste King L-3200 is one such unit. The grinding chamber has a stainless steel turntable, cast stainless steel impellers and a stainless steel grind ring.
On the other hand, InSinkErator Evolution Essential XTR f
eatures the MultiGrind technology that provides different stages of grind. Higher stages of grind enable the processing of more difficult food waste such as bones

Note 4:
  • Waste King L-3200  has a grind chamber made of corrosion proof glass filled polyester.
  • InSinkErator Evolution Essential XTR has a stainless steel grind chamber.
In either case, you will never have to worry about corrosion.

Note 5:

Both units have sound insulation:
  • Waste King is built with a sound shell that helps prevent sound from escaping.
  • InSinkErator features advanced sound reducing technology that ensures less noise than a standard disposer.  This technology includes superior insulation around the motor, an anti-vibration sink mount, and an anti-vibration tailpipe to prevent sound transmission from vibrations. The sink baffle also helps prevent sound from escaping the throat of the disposer.   This proprietary SoundSeal technology built into the  InSinkErator Evolution XTR unit  makes its operation whisper quiet compared to most other garbage disposers​!

Note 6:
The removable splash guard makes it easy to clean.

Note 7:
Installation  of these units is pretty  straightforward and described in their provided user manuals. Both units  come with all parts needed to install. The following images show the various dimensions associated with the two units that need to be taken into consideration when installed:

​Note 8:
​Both units come with a built-in spout (or connection) for connecting to the dishwasher if needed, but you may have to buy separately a dishwasher connection kit (adapter, hose, etc.) if not already included with your purchase.
Waste King L-3200 already comes with the dishwasher adapter kit, but you may still need to buy a dishwasher connection kit if the dishwasher hose size does not match the included adapter.
See below Amazon products section for dishwasher connection kits for both products.​

Note 9:
The InSinkErator unit can simply be wired to your electrical source, but if  you prefer to plug it to an electrical outlet, you can use the power cord that can be separately obtained (see Amazon products section below for the power cord).
​Note that even though the Waste King unit comes with a power cord included, you can also hardwire the unit, if you prefer so.  The bottom of the unit is removable allowing you to remove the power cord and hardwire the unit to your power source.

​Note 10:
Waste King Legend 3200 comes with an 8-year warranty. The disposer also comes with a lifetime warranty against corrosion. Both warranties are limited to the original purchaser.
InSinkErator Evolution Essential XTR comes with a 6-year warranty commencing on the later of: (a) the date your InSinkErator product is originally installed, (b) the date of purchase, or (c) the date of manufacture as identified by your InSinkErator Product serial number. 


So which of the two garbage disposal systems to buy?

The two instant garbage disposers considered here are excellent products as shown by  the average rating each had received from Amazon customers at the time this article was written. Indeed, both products had received 4.5 stars (out of 5 stars).  There is a good chance that you would be quite  happy with either of these two products.

Note that, even though there is quite a large price difference between the two products, there are a couple of important  differences   that may justify the higher price of InSinkErator Evolution:
  • The stainless steel grind chamber of the InSinkErator features 2 grind stages that truly liquefy food waste while the Waste King unit is a one stage pulverizer.
  • The proprietary SoundSeal technology built into the  InSinkErator unit  makes its operation whisper quiet compared to most other available models.​
