InSinkErator Contractor 1000 1 HP Garbage Disposal (No Cord)
The InSinkErator Contractor 1000 1 HP Garbage Disposal is built with professionals in mind. It delivers full 1 horsepower grinding performance in a compact Power Series housing, ready to be hard-wired on site. If you’re a contractor, remodeler, or a confident DIYer who prefers a clean, wired-in installation instead of a plug-in cord, this is the version you’re looking for.
With a quiet Dura-Drive® induction motor, stainless steel grind components and a generous 8-Year We Come To You® in-home parts and labor service warranty, the Contractor 1000 is designed to handle demanding, everyday kitchen use while keeping call-backs to a minimum.

- Quick Lock® mounting system – helps simplify change-outs and new installs.
- Quiet Collar® sink baffle – helps contain noise and splashing at the sink opening.

Power & performance
With a full 1 horsepower motor, the Contractor 1000 sits firmly in the high-performance end of InSinkErator’s residential range. It’s designed to keep up with busy family kitchens, small rental properties, or remodel projects where the sink handles a lot of food prep and clean-up.
Used with plenty of cold water and sensible habits, the 1 HP motor can confidently deal with common scraps like vegetable peelings, small bones, fruit trimmings, pasta and rice. The goal isn’t to throw anything and everything down the drain, but to handle real-world kitchen waste without constant jams or stalls.
Noise levels
Contractor-grade doesn’t have to mean loud. The Contractor 1000 combines its Quiet Dura-Drive® motor with a Quiet Collar® sink baffle to help reduce operational noise compared to older, open-metal disposers. You’ll still hear it working, but in most kitchens the sound is more of a controlled hum than a harsh, rattling grind.
What comes in the box?

- Quick Lock® mounting hardware and instructions
- Quiet Collar® sink baffle, polished stainless steel sink flange and 1-piece stainless steel stopper
This specific configuration is supplied without a factory-installed power cord. That’s intentional: it gives contractors flexibility to hard-wire the unit or fit a cord that meets local code and job requirements. If you prefer a pre-corded version of this disposer, see the matching model below.
If you’re planning to add a cord kit to this no-cord model, be sure to follow all electrical codes and wiring instructions. For more on cord options, see our:
Installation & contractor-friendly design
The Contractor 1000 uses InSinkErator’s Quick Lock® mounting system, designed to speed up both replacements and new installs. If you’re swapping out an older InSinkErator unit, you may be able to reuse the existing mounting assembly, reducing time under the sink.
Because this configuration ships without a power cord, it is ideal when:
- The job requires a hard-wired connection to a junction box.
- You’re following local electrical codes that prefer or require wired disposers.
- You want control over cord length, outlet location, or the use of a specific cord type.

Who is the Contractor 1000 (no cord) best for?
This model is a solid fit if:
- You’re a plumber, contractor or DIYer comfortable with electrical connections and prefer hard-wired installations.
- You want a 1 HP disposer that can handle frequent use in a busy kitchen.
- You like the idea of a contractor-focused unit with an 8-year in-home parts and labor warranty.
- You don’t need a pre-installed cord and would rather choose cord length and routing yourself.
You might lean towards another model if:
- You want a plug-and-play corded unit – in that case, the Contractor 1000 with cord or Pro 1000 are better options.
- You’re replacing a basic builder-grade disposer in a budget-conscious rental – a Badger Series model might be more cost-effective.
Contractor 1000 FAQs
Can I add a power cord to the Contractor 1000 later?
Yes, many installers add a compatible power cord kit to the Contractor 1000. Always follow the wiring instructions included with the cord kit and comply with local electrical codes. If you are unsure, it’s safest to hire a licensed electrician.
Is the Contractor 1000 suitable for homes with septic systems?
Like other modern disposers, the Contractor 1000 can often be used with a properly sized and maintained residential septic system when operated as directed. However, always confirm with your septic professional and local plumbing regulations before installation.
How loud is the Contractor 1000 compared to older disposals?
The Contractor 1000’s Quiet Dura-Drive® motor and Quiet Collar® baffle help reduce noise compared to older, uninsulated units. It is not silent, but most homeowners notice a smoother, more controlled sound profile rather than a sharp, rattling grind.
What is the difference between the Contractor 1000 and the Pro 1000?
Both are 1 HP disposers, but the Pro 1000 is positioned as a higher-end, corded model with advanced noise reduction features and an 11-year in-home warranty. The Contractor 1000 focuses on straightforward, contractor-friendly installs with an 8-year in-home warranty.
Does the Contractor 1000 come with everything needed to install?
You receive the disposer unit, mounting hardware, sink flange, stopper and Quiet Collar® baffle. Electrical connections and any optional power cord kits, dishwasher connectors or plumbing fittings are supplied separately by the installer.
