Materials and Tools Needed
Before starting, gather the following tools and materials:
- New garbage disposal unit
- Plumber’s putty
- Screwdriver
- Wrench set
- Bucket or small container
- Pipe sealant
- Power drill (optional)
Step 1: Turn Off the Power
Safety is essential when working with electrical appliances. Locate the circuit breaker controlling your kitchen outlets and switch off the power to avoid electrical shocks. Also, ensure you have adequate lighting to see under the sink.
Step 2: Disconnect the Drain and Remove the Old Disposal (If Replacing)
- Place a bucket under the sink to catch any water left in the pipes.
- Use a wrench to loosen the nuts connecting the sink’s drainpipe to the disposal unit and the dishwasher hose, if applicable.
- Detach the old disposal by twisting it counterclockwise and lifting it off its mounting bracket.
- Clean the sink flange to ensure a smooth surface for the new unit.
Step 3: Install the Mounting Ring and Sink Flange
- Apply Plumber’s Putty: Roll plumber’s putty into a rope shape and place it around the sink flange. The putty creates a waterproof seal to prevent leaks.
- Place the Sink Flange: Insert the flange into the sink drain hole, pressing firmly to secure the putty.
- Attach the Mounting Ring: Below the sink, slip on the gasket and mounting ring and tighten the screws until it is secure. Remove any excess plumber’s putty around the flange.

Step 4: Prepare the Garbage Disposal Unit
- Attach the Disposal Mount: Follow the manufacturer’s instructions to attach the disposal unit to the mounting assembly under the sink.
- Knock Out the Dishwasher Plug: If your dishwasher connects to the disposal, use a screwdriver to knock out the small plastic plug inside the dishwasher inlet on the disposal.
- Attach the Discharge Tube: Connect the discharge tube to the garbage disposal unit.
Step 5: Wire the Disposal
If your garbage disposal is not pre-wired, follow these steps to wire it properly:
- Remove the Cover Plate: Locate the access panel at the bottom of the disposal and remove the cover plate.
- Connect the Wires: Connect the white (neutral) wire to the white lead, and the black (hot) wire to the black lead on the disposal.
- Secure the Ground Wire: Attach the ground wire to the green grounding screw on the disposal unit.
- Replace the Cover Plate: Once wired, replace the cover plate to secure the wiring.
If you’re unsure about handling wiring, consider consulting a professional. How to Join has more resources on wiring and home electrical projects.
Step 6: Mount the Disposal Unit
- Align and Lock the Disposal: Lift the disposal unit to the mounting ring. Align the unit, and turn it clockwise until it locks into place. Ensure it’s firmly secured.
- Connect the Dishwasher Hose (optional): If you have a dishwasher, connect its drain hose to the disposal unit.
Step 7: Connect the Drain Pipes
- Attach the Drain Trap: Connect the disposal’s discharge pipe to the sink’s drain trap using a wrench to secure the nuts. Ensure it’s tightly connected to prevent leaks.
- Seal Connections: Apply pipe sealant to any threaded connections to create a watertight seal.
Step 8: Test the Disposal
- Turn on the Water: Run water into the sink to check for any leaks under the sink.
- Turn on the Power: Restore power to the kitchen circuit, then test the disposal by turning it on.
- Check for Leaks: Inspect all connections carefully to ensure there are no water leaks. Tighten any loose connections as needed.
Step 9: Clean Up and Maintain
Once your disposal is installed and working, clean up any remaining tools or materials. Regularly maintain your garbage disposal by running cold water during use and avoiding hard or fibrous foods that can damage the blades.
Troubleshooting Tips
- Disposal Won’t Turn On: Ensure the power is on and the reset button on the bottom of the unit is pressed.
- Leaks: If you notice leaks, check all connections and seals for tightness. Use additional plumber’s putty if necessary.
- Noisy Operation: If the disposal is unusually noisy, it may have something stuck in the grinding chamber. Turn off the power and remove any obstruction.
