How It Performs in Real Kitchens
Owners consistently comment that this Evolution Cover Control is very quiet compared to older disposals. One reviewer who replaced a 10-year-old cover-control model notes that the new unit runs noticeably softer while still giving strong grinding performance. Another customer calls it an “excellent batch feed disposal” and highlights how smoothly it runs once installed.
Where feedback becomes mixed is around the installation experience. Some buyers find the EZ Connect system straightforward, while others mention that the unit’s larger size makes the install more involved and, in a few cases, more expensive if you hire a plumber. The housing is tall, so tight under-sink spaces can feel cramped during the install.
Overall rating trends sit around the low four-star range, with the majority of reviews being 5-star. The lower ratings usually come from buyers frustrated with vague instructions, missing cords or the amount of effort required to fit the disposal into older plumbing layouts.
Noise Levels – Is It Really That Quiet?
No garbage disposal is truly silent, but the Evolution Cover Control 3/4 HP is a big step up from entry-level models. Multi-layer sound insulation and the Evolution housing design help dampen vibration and motor noise. Several owners describe it as “very quiet” and noticeably softer than the unit it replaced.
Because this is a batch-feed unit, the cover itself also blocks sound. With the stopper in place and the sink full, noise is further muffled compared with a continuous-feed disposal running with the drain open.
Installation & Compatibility
The Evolution Cover Control is designed to fit a standard 3-bolt style sink flange and run on a 120V 
household circuit. Out of the box, it is normally set up for hardwired installation using the EZ Connect adaptor, and the power cord is not usually included. If you plan to plug the unit into an outlet instead of hardwiring, you will need an optional power cord kit.
- Check cabinet clearance – at about 15" tall, this disposal may feel large in shallow under-sink spaces, especially with deep sinks or added water filtration systems.
- If you are not comfortable working with electrical wiring or complex plumbing, budgeting for a professional install is wise. Some reviewers noted that the labour cost was higher than they expected.
- For dishwashers, you can connect the drain hose to the disposal’s inlet once the knockout plug is removed.

Pros & Cons – Evolution Cover Control 3/4 HP
Pros
- Very quiet for a 3/4 HP disposal – big improvement over older models.
- Batch-feed CoverStart® design adds a layer of safety and keeps the sink covered while running.
- Three-stage MultiGrind® handles tough scraps and reduces the risk of clogs.
- Advanced Series build quality with stainless-steel grind components.
- Septic-system compatible when used with properly maintained systems.
- Long, in-home service style warranty for extra peace of mind.
Cons
- Taller body – can be a tight fit in smaller under-sink cabinets.
- Instructions are sometimes described as vague or confusing.
- Power cord is typically sold separately.
- Professional installation can be expensive if plumbing needs adjustment.
- Batch feed isn’t ideal for users who prefer continuous-feed convenience.
Who Is the Evolution Cover Control 3/4 HP Best For?
This model is a great fit if:
- You want Evolution-level quietness without going all the way to a 1 HP unit.
- You prefer the added safety of a batch-feed disposal that only runs with the cover in place.
- Your household generates a steady amount of food waste but not extreme volumes every day.
- You have enough cabinet height to comfortably fit a taller disposal.
If you want maximum grinding power for large families or heavy cooks, a 1 HP Evolution model may be the better option. If budget is your priority and noise is less of a concern, one of the Badger or entry-level Pro Series units can still do the job for less.
Customer Review Highlights
- “Quiet, works well, no surprises installing it” – customers love that the unit runs much more quietly than their 10-year-old models and that the upgraded packaging protects the disposal even when the shipping box arrives a bit battered.
- “Well-made machine but very expensive to install” – owners are happy with performance and quietness, but some were surprised at the plumbing cost for the larger housing. It’s worth getting a quote if you will be hiring a pro.
- “Worth the price” – reviewers praise the magnetic on/off cover as a big improvement over older switch designs and say the batch-feed setup works great once installed.
Looking across the full set of reviews, most customers feel the Evolution Cover Control delivers exactly what it promises: strong grinding, quieter operation and safer batch-feed usage. The main complaints focus on installation complexity, unclear instructions and the extra cost of accessories like the power cord.
FAQs – Evolution Cover Control 3/4 HP
Is this a batch-feed or continuous-feed disposal?
The Evolution Cover Control is a batch-feed model. It only runs when the magnetic cover is inserted and turned, which many families prefer for safety and to keep small items from falling into the grind chamber.
Does it come with a power cord?
Usually, no. Most listings include the EZ Connect hardwire adaptor, not a plug-in cord. If you want a standard plug connection to a wall outlet, you will need to purchase a separate power cord kit or have your installer provide one.
Will it work with a septic system?
Yes, the Evolution Cover Control is described as septic-safe when used with a correctly sized and properly maintained septic system. If you have any doubts, confirm with your local plumber or septic professional.
How loud is it compared to a basic disposal?
Owners generally find this model much quieter than older, builder-grade disposals. SoundSeal® insulation and the covered batch-feed design both help reduce noise, though you will still hear the motor and grinding action while it runs.
Will it fit under my sink?
At around 15 inches tall, this unit is taller than many entry-level disposals. Measure from the bottom of your sink to the cabinet floor and allow extra room for the discharge elbow and plumbing. If space is tight, you may want to compare measurements with a more compact Evolution or Badger model.
Our Verdict on the Evolution Cover Control 3/4 HP
The InSinkErator Evolution Cover Control 3/4 HP is an excellent choice if you want a quieter, safer disposal with premium grinding performance. It isn’t the cheapest option in the line-up and may require more effort to install, but once it is in place the combination of quiet running, batch-feed safety and a strong warranty makes it a very compelling upgrade over older builders’ models.
If you’re comfortable with the extra height and potential install cost, this Evolution unit offers a great balance of performance, peace of mind and long-term value.
