Our take on the InSinkErator Evolution 1 HP Continuous Feed Garbage Disposal

The InSinkErator Evolution is a continuous-feed garbage disposal with a 1 HP motor that spins its stainless steel grinding components at 1725 rpm. It uses the company's multi-stage grinding design, which handles tougher scraps than single-stage units, and its galvanized steel housing is lined with sound insulation to keep the grind quieter. The 8.25-inch diameter and 12.25-inch height fit standard sink openings, and it has a dishwasher drain connection. It suits households that cook often and want fewer jams and less noise than a basic half-horsepower unit offers, and its 10-year warranty is longer than the coverage on most entry-level disposals.

Pros
  • 1 HP motor grinds tough scraps faster than half-horsepower units

  • Sound insulation keeps it quieter than uninsulated disposals

  • Dishwasher drain connection simplifies plumbing
  • 10-year warranty outlasts most entry-level disposals
Cons
  • Continuous feed means you cannot safely reach in while it runs

  • Needs a properly sized circuit and a sink flange that fits its 8.25-inch body
  • Premium build costs more than basic 1/2 HP units

Questions and answers

How does the Evolution 1 HP compare with a basic 1/2 HP disposal?
It grinds faster and handles tougher scraps thanks to its 1 HP motor and multi-stage grinding, and its sound insulation makes it quieter. Basic half-horsepower units are lighter and simpler but jam more on fibrous waste.
Is it quiet enough for an open kitchen?
It is quieter than uninsulated disposals because of its sound insulation, but it is not silent. Expect a low grind rather than a loud rattle.
What are the dimensions and will it fit my sink?
It is 8.25 inches in diameter and 12.25 inches tall, a standard size for under-sink mounting. Check cabinet clearance and that your sink flange matches before installing.
Does it connect to a dishwasher?
Yes, it has a dishwasher drain connection, so a dishwasher hose can drain through the disposal.
What does the warranty cover?
It carries a 10-year warranty from InSinkErator, which is longer than the coverage on most entry-level disposals.
Continuous feed or batch feed?
It is continuous feed, so it runs while you add scraps. That is faster for big meals but means you must never reach into the grind chamber while it is on.
Where is the InSinkErator Evolution 1 HP Continuous Feed Garbage Disposal cheapest?
At eBay, for $272.45, 24% under what the other stores charge, as of our latest check.
Where can I buy the InSinkErator Evolution 1 HP Continuous Feed Garbage Disposal?
10 stores we checked sell it, including Life and Home, Max Warehouse, Pro Serve US, Factory Hardware Store, The Home Depot.
