Introduction
InSinkErator garbage disposals are engineered to simplify kitchen waste management and streamline food preparation. With a focus on user-friendly design, these units are compatible with standard plumbing and require minimal space for installation. This article provides a detailed overview of installation steps, safety precautions, maintenance routines, and technical specifications based on official documentation from InSinkErator. The information is intended for homeowners, plumbers, and DIY enthusiasts looking to install or maintain an InSinkErator garbage disposal unit in the United States.
Installation Overview
InSinkErator garbage disposals are designed for both new and existing kitchens and can be installed using standard plumbing and electrical connections. The installation process is supported by instructional videos and written guides provided by the manufacturer, which outline the steps for connecting the disposal to the sink and power source.
The disposal unit is mounted under the sink using a flange that replaces the standard sink plug hole. The unit fits into the cabinet space beneath the sink and is typically connected to a discharge tube that leads to the plumbing system. For hot water taps, the unit is mounted on the work surface, while the compact hot water tank is installed beneath the sink.
All InSinkErator garbage disposal units come with comprehensive installation instructions. While self-installation is possible for experienced individuals, most users prefer to hire a licensed plumber and electrician to ensure proper setup and compliance with local codes.
Tools and Materials Required
The InSinkErator Badger disposer includes several components and tools necessary for installation. These include:
- Stopper: Used to secure the flange in place.
- Sink Flange: Fits into the sink hole and supports the disposer.
- Fiber Gasket: Provides a watertight seal between the flange and sink.
- Backup Flange: Additional support for the flange.
- Mounting Ring: Helps secure the disposer to the sink.
- Screws: For fastening the unit to the mounting ring.
- Snap Ring: Ensures a secure connection between components.
- Wrenchette: Tool for tightening the mounting ring.
- Disposer Unit: The main garbage disposal mechanism.
- Discharge Tube, Gasket, and Flange: Connect the disposer to the plumbing system.
- Bolts: Additional hardware for securing the unit.
Additional tools and materials that are not included but may be required for installation include:
- Wire Nuts: For electrical connections.
- Cable Connector: To secure the power cord.
- Plumber’s Putty: For sealing the flange to the sink.
Installation Steps
- Prepare the Sink Hole: Ensure the sink has a standard 90mm hole. If not, modify it to accommodate the disposer.
- Install the Flange and Gasket: Insert the sink flange into the hole and place the fiber gasket underneath.
- Mount the Disposer: Align the disposer with the flange and secure it using the mounting ring and screws.
- Connect the Plumbing: Attach the discharge tube to the disposer and connect it to the plumbing system.
- Secure the Unit: Use the wrenchette to tighten the mounting ring and ensure the disposer is stable.
- Electrical Connection: Connect the power cord to a grounded outlet. Follow local electrical codes to ensure proper grounding and safety.
- Final Checks: Inspect the installation for leaks and ensure the unit is properly grounded.
For advanced models such as the Lift & Latch series, a stationary ring with a small notch simplifies installation by allowing the unit to be latched into place with a slight turn.
Electrical Safety and Grounding
Proper grounding is essential to prevent electric shock. The disposer must be connected to a grounded outlet and follow local electrical codes. For permanently connected units, a grounded wiring system is required.
- Grounding Instructions: Ensure the disposer is properly grounded using a grounded outlet and wiring system.
- Electrical Safety: Improper grounding can lead to electric shock. If unsure, consult a licensed electrician.
- Avoid Modification: Do not modify the plug or force it into an outlet. Ensure all wiring is in compliance with local codes.
Maintenance and Cleaning
Regular maintenance is necessary to keep the garbage disposal operating efficiently. While the ice cleaning method is available, InSinkErator recommends alternative methods for optimal results.
To clean the disposer:
- Remove Obstructions: Use tongs to remove any objects stuck in the unit.
- Reset the Motor: If the disposer is jammed, allow the motor to cool for 3–5 minutes and press the red reset button located on the bottom of the unit (see Figure B).
- Check Electrical System: If the disposer is unresponsive, check the service panel for tripped breakers or blown fuses.
The Jam-Buster™ wrench can be used to manually turn the unit if it becomes jammed. Insert the wrench into the bottom center hole of the disposer and gently turn it to free any blockages.
Safety Precautions
- Fire Hazard: Avoid storing flammable items near the disposer.
- Leak Hazard: Regularly inspect the unit for leaks and reseal the flange if necessary.
- Non-Compostable Items: The disposer can handle food waste such as meat, bones, and dairy products, which are not suitable for home composting.
- Avoid Non-Food Items: Do not dispose of paints, solvents, household cleaners, automotive fluids, or plastic wrap in the unit.
- Proper Use: The disposer should not be used for purposes unrelated to food preparation, such as baby bathing.

Additional Features and Accessories
InSinkErator offers several accessories that enhance the functionality of its garbage disposal units:
- Dishwasher Inlet: Allows the disposer to be integrated with a dishwasher.
- Tailpipe and Sink Baffle: Ensure proper drainage and reduce noise during operation.
- Lower Mounting Ring and Mount: Provide additional stability for the unit.
For users interested in hot water applications, InSinkErator offers instant hot water dispensers such as the HC3300, H3300, HC1100, and GN1100. These units provide filtered near-boiling water and are designed to fit alongside the main faucet.
Environmental Considerations
Food waste from InSinkErator disposals is processed into fine particles and flushed through the plumbing system. Once at the wastewater treatment facility, it can be converted into biogas and fertilizer. This process supports resource recovery and reduces landfill waste.
A study conducted by the University of Sheffield confirmed that properly ground food waste does not cause sewer blockages and is comparable in composition to human waste, which is routinely handled by sewer systems.
Recycling and Disposal of Old Units
Old garbage disposal units can be recycled as scrap metal. Since these units are primarily made of metal, they can be processed to recover materials such as copper, aluminum, and steel.
For users interested in recycling their old disposer, InSinkErator recommends using the Earth911 recycling locator to find a local facility that accepts metal waste.
