What Makes The Evolution Excel Unique? 

Evolution Excel is the latest model in the Evolution series, providing all the essential features that high-quality garbage disposers have.  

Here are a few features of this exceptional InSinkErator disposal: 

Dura-Drive Motor Technology 

This latest model by InSinkErator garbage disposals comes with a state-of-the-art Dure-Drive motor technology to improve its overall performance. It's one of the most popular drive mechanisms in garbage disposers, enhancing motors' durability and accuracy.  

With a strong, heavy-duty one horsepower induction motor along with 1725 RPM grinding speed, this InSinkErator appliance can smoothly deal with every type of food scrap imaginable and unimaginable with ease.  

SoundSeal Technology 

One of the most prominent features of InSinkErator Evolution Excel garbage disposal is SoundSeal Technology.  

The SoundSeal tech makes it quiet during operation, so you can easily converse with others and enjoy your kitchen experience.  

Under typical situations, it has a noise level of 25dB, which is similar to a human whisper. 

Stainless Steel Grind Chamber

The InSinkErator Evolution Excel is designed for grinding tougher food wastes in large quantities, which is why it has a stainless-steel chamber.  

Unlike galvanized steel, stainless steel grind chambers can chop up even the hardest foods into the tiniest particles. This is because all its components are made from anti-corrosive and anti-rust stainless steel, making it durable. 

3 Stage Multi-Grind Technology 

Evolution Excel Garbage Disposal multi grind

The Evolution Excel is slightly different from other models due to its 3 stage multi-grind technology.

The first technology is the "GrindShear Ring," designed to enhance its angles and cutting edges. As a result, food scraps that press against its ring will be cut instantly.   

In addition to that, the impellers have additional blocks to shape the "Tri-Action Lug System," ensuring all food scraps coming in contact with the GrindShear Ring are chopped till the required texture is attained.  

Right underneath the turnplate is the "Undercutter Disk." It works similarly to the ring and lug system; it slashes everything that comes from the gaps into tiny pieces.   

Auto-Reverse System  

InSinkErator garbage disposals have unique anti-jam mechanics, such as the Auto-Reverse system. Whenever big lodges are on their way, it acknowledges them immediately. Then, if required, it sends signals directly to the induction motor, making it rotate reversed to prevent the entire mechanism from being jammed in a particular position.  

Jam Sensor 

But how does the Evolution Excel know if the jam or clog is imminent? Well, thanks to its "Jam-Sensor" circuit, it senses jams and clogs by evaluating the motor's torque. Suppose it picks up on a clog, the torque is raised (about 500%), and pulse (60-time a second) is also increased. As a result, it causes a pounding action, which breaks even the most challenging objects into small pieces.  

Quick-Lock Sink Mount  

Thanks to the Quick-lock Sink Mount Tech, set up is a breeze. With this feature, you can easily replace your existing garbage disposal by unscrewing it and placing the new appliance. In addition, with this advanced technology, you can install the device by yourself, saving time and money.   


This latest model has a 7-year limited in-home warranty, which means if the unit stops working or malfunctions, the company will fix it no matter what.

 In short, your appliance will get fixed quickly without you having to leave your couch.

The Evolution Excel garbage disposer is not an entry-level disposer. Instead, the unit boasts a one-horsepower induction motor supported by Dura-Drive technology, which means it can swiftly dispose of all sorts of waste you put in.  

In addition to that, the high-quality stainless-steel construction of the unit provides InSinkErator to give users an industry-leading seven-year warranty period, covering both in-home labor and parts. 

This waste disposal includes all the added features required from premium units. However, despite featuring all the superior qualities, installing it is like shooting fish in a barrel. In other words, you can easily install it by yourself! 

This InSinkErator model is ideal for homeowners looking for an upgraded unit that isn't costly. 


Evolution Excel Garbage Disposal installation

What we liked most about this InSinkErator model was the stainless-steel mounting bracket, better known as "Quick-Lock sink mount."

 It provides you with an easy and fast way to replace your current disposal or assemble a new one.  

All you've got to do is spin it 'off' for dismounting and spin it 'on' for mounting. 

In addition, InSinkErator provides users with a clear and easy-to-read manual with all its garbage disposers. 

Despite being a compact device, it weighs around 23 pounds, so it's best to take assistance when you're mounting it, especially during alignment. If you don't have someone to help you with, you can use a jack or thick books to hold your appliance in place. I found this tip extremely useful in the installation process.  

Make sure to tire out the drainage plug before connecting with the dishwasher. Perform it before you mount the unit. If the sink diameter is greater than 3/8 inch, change the current 1-1/2 inch screws to 1-1/8-inch screws.  

Typically, the entire installation process will take about one to two hours most. If you're replacing smaller-size disposal, you may have to redo every plumping pipe. This is because the existing configuration might not fit bigger units. Thus, the time duration could be more than expected.  

This InSinkErator model doesn't come with the following three things: 

  • Plumbers putty 
  • Cable connector  
  • 2 number wire nuts 

If you've got an outlet underneath the sink, you'll have to purchase a power cable separately.  

Usage Expectations 

With a robust one-horsepower induction Dura-Drive tech motor, the appliance works exceptionally well. Due to its sharp and potent blades and three-stage grinding tech can slash almost all food remains easily. Furthermore, like other InSinkErator units, it also has a superior stainless-steel grinding chamber, ensuring it lasts longer. 


You can utilize Evolution Excel for many food scraps such as chicken bones, coffee grounds, fruit rinds, and more. Your appliance will chop all these scraps effortlessly, ensuring continuous flow via drainage pipes.  

However, with time, food remains may accumulate in its chamber or baffle. And if there's an odor coming from the appliance, it shows there's a food build-up and grease due to poor water flow while operating.  

Nevertheless, here are the steps to wash your unit: 

  • Turn the appliance off and disconnect its power supply 
  • Put the stopper in the sink opening  
  • Fill the kitchen sink with water. Make sure to fill it halfwa
  • Mix water with ¼ cup soda 
  • Switch on the disposal and extract the stopper from your kitchen sink so loose particulates are washed  
  • Extract the "Quiet-Collar Sink Baffle." You can clean it with your hands or in the dishwasher 


This model by InSinkErator is equipped with two defenses, such as "Auto-Reverse system" and "Jam-Sensor Circuit," to prevent it from clogging or jamming during grinding.  

However, in case the appliance gets jammed, fix it by following these steps: 

  • Turn off water and disposal  
  • Insert the wrench into the unit from beneath
  • Work the wrench back and forth till it completes one revolution  
  • Carefully take out the wrench  
  • Reach into the disposal with tongs or pliers and remove the objects 
  • Allow the motor of your unit to cool down for approx. 3 to 5 minutes 
  • Press lightly the "red" reset button
