Key features & benefits
1 HP motor with 3-stage MultiGrind® performance
At the heart of the PRO1000LP is a 1 HP Dura-Drive® induction motor paired with 3-stage MultiGrind® Technology. Compared to standard single-stage disposers, this setup is designed to grind food scraps more finely, helping reduce the chance of clogs further down the line. For households that cook a lot and routinely push tougher scraps through the disposal, having extra horsepower and additional grind stages is a noticeable upgrade.
SoundSeal® technology for quieter operation
Despite its power, the PRO1000LP uses SoundSeal® technology and a Quiet Collar® sink baffle to keep noise levels under control. Many reviewers comment that the unit runs very quietly for a 1 HP model, and some note that they can hold a conversation in the kitchen while it’s running. It won’t be silent, but it’s a big step up from basic builder-grade units.
Jam-Sensor™ Circuit for tough situations
A standout Pro Series feature is the Jam-Sensor™ Circuit. If the disposal senses resistance from a tough jam, it automatically boosts motor torque to break through. This can help prevent the frustration of repeated manual resets when heavier scraps or accidental items get into the grind chamber. Used correctly, it’s a useful safety net for busy kitchens.
Low-profile design with stainless-steel grind components
The PRO1000LP is described as offering “Super 1 HP performance in a low-profile design”. With a relatively compact height and a narrower body, it can be easier to fit under some sinks than bulkier 1 HP models, while still using stainless-steel grind components for durability. This makes it an interesting option when you want maximum power, but cabinet space is still at a premium.
What real owners are saying
The PRO1000LP holds an average rating of around 4.2 out of 5 stars from a smaller pool of reviews (just over twenty). That’s solid, but not as strong or as well-sampled as the more popular Evolution models. Themes include:
- Quiet and powerful: multiple reviewers praise how quiet and heavy-duty the unit feels once installed.
- Long-term expectations: some buyers are replacing older InSinkErator units that lasted decades and hope this one does the same.
- Mixed experiences: a few reviews mention issues such as leaks or early problems, so correct installation and checking all seals is critical.
Pros & cons
What we like
- Full 1 HP Dura-Drive® motor with 3-stage MultiGrind® performance.
- SoundSeal® and Quiet Collar® for quieter operation compared with many 1 HP competitors.
- Jam-Sensor™ Circuit helps power through tougher jams automatically.
- Low-profile design can be easier to fit in some cabinet layouts.
- Stainless-steel grind components for long-term durability when correctly installed and used.
Things to keep in mind
- The PRO1000LP is more niche and less widely reviewed than mainstream Evolution models.
- A small number of owners report issues such as leaks or early failures, suggesting installation quality is especially important.
- Power cord is not included, so you’ll need a separate cord kit or hardwired connection.
- Pricing is typically higher than 3/4 HP models like the PRO750, so make sure you truly need the extra power.
PRO1000LP vs other InSinkErator models
If you’re trying to decide where the PRO1000LP fits in the Evolution and Pro Series lineup, here’s a quick comparison:
| Model | Motor | Grind stages | Noise level | Highlights |

| Evolution 1 HP | 1 HP | 4-Stage MultiGrind® | Very quiet | Top choice for heavy home use with the finest grind and excellent noise reduction. |

Frequently asked questions
Is the PRO1000LP overkill for most homes?
For light or average use, a 3/4 HP model such as the PRO750 or an Evolution 0.75 HP will usually be enough. The PRO1000LP is best suited to households that cook frequently, handle tougher scraps and specifically want 1 HP power with extra jam protection.
How quiet is the PRO1000LP?
Thanks to SoundSeal® technology and the Quiet Collar® sink baffle, many reviewers say it runs very quietly for a 1 HP disposal. You will still hear it, but the tone is more of a controlled hum than a harsh grind.
Does the PRO1000LP come with a power cord?
No. The PRO1000LP is supplied as a disposer-only unit. You’ll need to hardwire it or use a separate power cord kit if you prefer a plug-in installation.
Is the PRO1000LP difficult to install?
If you’re replacing an existing InSinkErator model with a Quick Lock® mount, the physical swap is often straightforward. However, because this is a 1 HP Pro Series model and does not include a cord, we recommend having a professional handle the electrical side if you’re not comfortable with wiring.
How reliable is the PRO1000LP?
Most owners report quiet, strong performance, but the review sample is relatively small and a few customers mention issues such as leaks or early problems. Ensuring correct installation, properly tightening seals and using the unit as directed will give you the best chance of long-term reliability.
