Installing a Garbage Disposal: A Step-by-Step Guide
Installing a garbage disposal is a moderately challenging DIY project that can save you money compared to hiring a plumber. Here's a breakdown of the process:
1. Safety First
- Turn off the power! Locate the circuit breaker that controls the kitchen sink outlet and switch it off. This is absolutely critical to prevent electric shock.
- Wear safety glasses. Debris can fall and injure your eyes.
2. Removing the Old Disposal (If Applicable)
- Disconnect the power cable: Unscrew the cover plate on the bottom of the old disposal. Disconnect the wires inside. Make a note of which wire goes where, or take a photo, for reassembly.
- Detach the discharge pipe: Loosen the slip nuts that connect the disposal's discharge pipe to the drain pipes.
- Loosen the mounting ring: Use a screwdriver or specialized tool to loosen the mounting ring that holds the disposal in place. Turn it counterclockwise. This can be difficult if it's corroded.
- Remove the old disposal: Once the mounting ring is loose, the old disposal should detach. It might be heavy, so support it while removing it.
- Remove the old mounting assembly: This usually involves loosening screws or clips. Clean the sink flange area thoroughly.
3. Installing the New Mounting Assembly
- Install the new sink flange: Apply plumber's putty to the underside of the new sink flange and press it firmly into the sink opening.
- Secure the mounting ring: From underneath the sink, install the rubber gasket, fiber washer, and mounting ring. Tighten the screws or snap the clips to secure the assembly. Scrape away any excess putty.
4. Wiring the Disposal
- Connect the power cable: Feed the power cable through the opening on the bottom of the disposal. Connect the wires according to the instructions that came with your disposal. Typically, black goes to black (hot), white to white (neutral), and green or bare copper to the grounding screw. Ensure connections are secure with wire connectors.
- Secure the cover plate: Replace the cover plate and tighten the screws.
5. Attaching the Disposal
- Align the disposal: Line up the disposal with the mounting ring and twist it into place. It should lock securely.
- Connect the discharge pipe: Attach the discharge pipe to the disposal and to the drain pipes using slip nuts. Make sure the connections are tight.
6. Testing
- Run water: Turn on the water and check for leaks around the sink flange, discharge pipe, and disposal body. Tighten connections if necessary.
- Turn on the power: Flip the circuit breaker back on.
- Test the disposal: Run water into the disposal and turn it on briefly. Listen for unusual noises or vibrations.
- Continue to check for leaks: Monitor the disposal for leaks over the next few days.
Important Considerations:
- Plumber's Putty: Use a generous amount, but clean up excess for a neat appearance.
- Dishwasher Connection: If your old disposal had a dishwasher connection, ensure you knock out the plug on the new disposal's inlet before connecting the dishwasher hose. This must be done or the disposal will back up into your dishwasher.
- Size & Horsepower: Select a disposal size and horsepower appropriate for your household's needs.
- Disposal Care: Avoid putting hard items down the disposal. Run cold water when operating.
