InSinkErator PRO750 with Cord Garbage Disposal Review
The InSinkErator PRO750 with Cord is a Pro Series 3/4 HP disposal that borrows key technology from the Evolution line — quieter SoundSeal® operation and MultiGrind® performance — but packages it in a compact, contractor-focused unit with a factory-installed power cord. It’s designed for tighter cabinet spaces, including popular farmhouse sinks, while still giving you pro-level performance and build quality. In this review, we’ll look at how it fits, how quiet it runs, what owners say after years of use, and whether the PRO750 is the right upgrade for your kitchen.

Who the PRO750 with Cord is best for

- Kitchens with restricted cabinet space or under-sink obstacles, including farmhouse sinks.

Key features & benefits
Compact design for tighter cabinets and farmhouse sinks
One of the biggest advantages mentioned by reviewers is how well the PRO750 fits into smaller sink bases. Several owners installed it under farmhouse sinks or in tight remodels where height and diameter matter. Despite the compact footprint, it still houses a 3/4 HP motor and multi-stage grind system, so you aren’t trading performance for size.
SoundSeal® Technology for a quieter kitchen
The Pro Series borrows from the Evolution line by using SoundSeal® Technology, including the Quiet Collar® sink baffle and insulated housing. Many long-term owners comment that the PRO750 runs very quietly compared with older disposals, with one reviewer noting that their contractor was impressed by how muted the sound level was once installed. If you’re used to the harsh buzz of basic disposers, this will feel like a big upgrade.
MultiGrind® 2-stage grinding power
The PRO750 features MultiGrind® Technology with two grinding stages, compared with the single-stage systems found in standard disposals. This helps break down tougher food scraps more effectively, reducing jams and helping waste move more smoothly through the drain. Owners report that it handles everyday kitchen scraps easily and rarely jams when used correctly.
Factory-installed power cord for easier installation
Unlike many Evolution models that are supplied ready for hardwiring, the PRO750 arrives with a factory-installed power cord. That means no wiring the cord inside the base and no additional kit needed if you’re plugging into an outlet under the sink. Several reviewers say installation was “easy and quick”, and many had their plumber or contractor handle the job in a single visit.
Built for long-term reliability
Between its stainless grind components, Pro Series build quality and in-home warranty coverage, the PRO750 is designed as a long-term solution rather than a quick fix. Many reviewers are upgrading from older InSinkErator units that lasted well over a decade. While a small number of customers mention mixed experiences with durability, the overall feedback is strong, and most consider it a solid, quiet, reliable upgrade.
Real customer feedback
Across more than 200 Amazon reviews, the PRO750 with Cord holds an average rating of around 4.6 out of 5 stars. Here are some common themes:
- Noise level: frequently praised as very quiet or “muted” compared to older units.
- Ease of installation: many homeowners and contractors report simple, straightforward installs.
- Fit and size: repeatedly noted as a great choice for restricted cabinets and farmhouse-style sinks.
- Performance: users say it does exactly what a disposal should do — clears food quickly without fuss.
- Durability: most feedback is positive, though a few reviews mention concerns about long-term robustness, so correct installation and use are important.
Pros & cons
What we like
- Compact body that fits where larger Evolution models may struggle.
- 3/4 HP MultiGrind® motor for a good balance of power and efficiency.
- SoundSeal® Technology and Quiet Collar® baffle for quieter operation.
- Factory-installed power cord saves time and money vs buying a separate kit.
- Strong customer satisfaction with noise level, performance and ease of use.
Things to keep in mind
- Not as powerful as a full 1 HP Evolution model for very heavy-duty use.
- Some mixed feedback on long-term durability, so correct installation and avoiding misuse are important.
- Slightly higher price than basic Badger or contractor-grade units.
PRO750 vs other InSinkErator disposals
Trying to decide if the PRO750 with Cord is the right fit? Here is how it compares to a few related models:

| Evolution 0.75 HP | 3/4 HP | Multi-stage | Quiet | Great all-rounder for family kitchens, typically hardwired (cord kit extra). |
| PRO750 with Cord (this model) | 3/4 HP | MultiGrind® 2-stage | Quiet with SoundSeal® | Compact, quiet and comes with a factory-installed cord for easy installs. |
| Evolution 1 HP | 1 HP | 4-Stage MultiGrind® | Quietest | Best choice for heavy users who want maximum power and the finest grind. |

Frequently asked questions
Is the PRO750 with Cord a good choice for small cabinets?
Yes. The PRO750 is specifically described as a space-saving model and many reviewers mention that it fits well under smaller sink bases and farmhouse sinks where height and width are limited.
How quiet is the PRO750 compared with basic disposals?
Thanks to SoundSeal® Technology and the Quiet Collar® sink baffle, owners consistently describe the PRO750 as very quiet and less intrusive than older or builder-grade units. You’ll still hear it running, but the tone is more of a low hum than a harsh grind.
Does the PRO750 come with a power cord?
Yes. Unlike many Evolution-branded models, the PRO750 is supplied with a factory-installed power cord, making it easier to plug into an existing under-sink outlet without buying a separate kit.
Can the PRO750 replace my existing InSinkErator disposal?
In many cases, yes. If you already have a Quick Lock® style mount from a previous InSinkErator unit, installation can be as simple as swapping the disposer body and connecting the plumbing and power. Always check your current mount and plumbing configuration first.
Is the PRO750 powerful enough for a family that cooks often?
For most families, the 3/4 HP motor and MultiGrind® system offer plenty of power for day-to-day use. If you regularly grind large volumes of tough scraps and bones, you may want to consider stepping up to an Evolution 1 HP model instead.
