InSinkErator Evolution Compact 3/4 HP Household Garbage Disposer

“Built to silently grind”

We’ve all had that experience of trying to figure out what we threw down the sink that won’t go down all the way to the pipes. I personally do not like this kind of situation because it is absolutely irritating. Good thing the old disposer was replaced by InSinkErator Evolution Compact. And frankly, the unit is working quiet effectively. It did live up to the reviews I read about the unit. And from the name itself, it did fit okay under my sink.

The name itself says it all

It is a disposal unit from the Evolution series and as mentioned in the name, it is really compact. This unit is relatively smaller than the other Evolution series. It is around 10% smaller than the average food disposers that are available in the market. It is ideal for kitchen owners with limited space in the sink or prefers to have a larger area underneath it. It being small is one my favorite product feature. Now I have more room under the sink to put in my kitchen clutter. It is a good space saver.

The unit chamber can hold about 34.6 oz. of food waste only. Unlike the other InSinkErator that has a 40 oz. capacity. It is one of the downside of the disposer but if it goes any bigger then it won’t be compact anymore and it could go heavier. This unit is somehow near to the Evolution Space Saver which features the same size and capabilities. Speaking about the size, the unit is measured at 8x8x12 inches and weight at about 19.4 pounds, the grind power which is about 120 rpm is goof enough to make up for its size.

Grinding with power

As mentioned before, the unit might be small but the grinder works adequately. The package also mentioned that the disposer is equipped with a multi grind technology that delivers the best grinding process. I did notice that it does grind up everything pretty well and so far there are no waste getting jammed inside. Though it is mentioned in the product description that it comes with a tri action lug system that can liquefy food for safety passage to the septic tank, I think the reason why it doesn’t jam at all is due to feeding it with food scraps in small portions than shoving it all at once.

I also noted that against a standard disposer, the level of quietness while operation is relatively outstanding. It does deliver the expected quiet food crushing because of the sound seal technology that was placed in the disposer. But just because I said it works quietly, it does not mean that you won’t hear a thing. It would still hum and you can hear the grinders working, it’s just that the noise it makes is around mid-level.

Quick setup in the sink

Of all the things that come with the unit, the quick setup, or as others call it, installation is a breeze to do. The manual is comprehensible and you wouldn’t get lost with the process. A home and a kitchen owner like me who has a lot on their hands needs things to be done as soon as possible. That is why the easy twist on and off of the disposer for locking is handy. But I cannot guarantee you that you will have the exact same experience as mine was since I have good working hands in minor plumbing.

So that means, you can call in someone to install the unit for you if you know you can’t do it properly.

The Evo Compact has some other things included in the package. The unit comes with a sink baffle, jam-buster wrench for unexpected clogging, anti-vibration tailpipe mount to give you added silence, clamp, and a stopper. It also has a 36 inch cord making it convenient to plug and start the unit.


In terms of the warranty, InSinkrator Evolution Compact disposer comes with a 4-year in-home limited warranty. That includes the parts and service to be rendered for the repair.

Within the four years, it is absolutely recommended to always call in for a technician for any unusual noise or functioning of the disposer. Do not shrug them off since there is only four years in the warranty tag.

Pros and Cons

To give you a clear view on how I assess the unit, here are some of the noticeable pros and cons of the disposer.

  • The grinding is good
  • Quietness and build is good quality
  • In-home installation, just call for a technician
  • Runs with smoothness
  • Easy to maintain and clean
  • Warranty covers parts and service (installation included)
  • Doesn’t come with plumbers putty
  • Gasket is too tight, makes draining a bit slower
  • Warranty is limited for 4 years only

Bottom Line

In the end, the unit is acceptable despite being smaller in capacity. Its compact size and lighter weight, makes it much easier to mount. It gives out a strong vibration when you run the unit and the sink with water. You will also encounter some issues with installation since the weight can hold you down. With the price, it ranges with typical disposals in the market that has 3/4 HP in the motor. It is decently priced, the quality is good, though it looks cheap because of the plastic used as the cover. But I should say overall this is a product worth buying.
