how to install waste king garbage disposal

Installing a Waste King garbage disposal is a relatively straightforward process, but it does involve electrical and plumbing work, so make sure you’re comfortable with these tasks or consider hiring a professional if you’re unsure. Here’s a step-by-step guide on how to install a Waste King garbage disposal:

Materials You’ll Need:

  1. Waste King garbage disposal unit
  2. Mounting assembly (usually included with the disposal)
  3. Plumbers’ putty
  4. Electrical cable or cord (if not included with the disposal)
  5. Wire nuts and electrical tape (if not included with the disposal)
  6. Screwdriver
  7. Plumber’s wrench or adjustable wrench
  8. Bucket or container for catching water
  9. Safety glasses and gloves (recommended)

Step-by-Step Guide:

1. Preparation:

  • Before you begin, turn off the power to the area where you’ll be working. Locate the electrical circuit that powers the disposal and turn it off at the circuit breaker.

2. Disconnect the Old Disposal (if applicable):

  • If you’re replacing an existing garbage disposal, disconnect it from the electrical supply and plumbing. Disconnect the drainpipes and the electrical cable or cord.

3. Remove the Old Mounting Assembly (if applicable):

  • Loosen and remove the mounting ring and flange assembly from the sink drain opening. Clean off any old plumbers’ putty or debris.

4. Install the Mounting Assembly:

  • Place the new mounting assembly provided with the Waste King disposal into the sink drain opening. Ensure that it fits snugly.

5. Apply Plumbers’ Putty:

  • Apply a thin layer of plumbers’ putty around the top edge of the mounting assembly in the sink. This will help create a watertight seal.

6. Mount the Disposal Unit:

  • Carefully lift the Waste King disposal unit and align it with the mounting assembly in the sink. Rotate it to lock it into place, securing it with the mounting ring provided.

7. Tighten the Mounting Ring:

  • Use a screwdriver to tighten the mounting ring evenly until the disposal unit is secure and snug against the sink’s underside. Ensure that the disposal unit is properly aligned.

8. Connect the Drainpipes:

  • Reconnect the drainpipes to the disposal unit. You may need to use slip-joint pliers or a plumber’s wrench to secure the connections properly. Ensure that all connections are tight and leak-free.

9. Connect the Electrical Supply:

  • If your disposal unit came with a power cord, connect it to the disposal unit following the manufacturer’s instructions. If not, you’ll need to hardwire it to the electrical supply using wire nuts and electrical tape. Make sure to follow local electrical codes.

10. Test the Disposal:

  • Turn on the power at the circuit breaker to test the disposal. Run water and turn on the disposal to check for any leaks or unusual noises. Make sure it’s functioning correctly.

11. Secure the Disposal:

  • If your disposal unit has a mounting bracket, use it to secure the disposal to the cabinet wall or floor. This adds extra stability.

12. Final Check:

  • Double-check all connections and seals for leaks. Tighten any connections if necessary.

13. Complete Installation:

  • Finish the installation by attaching the drainpipe from the dishwasher (if applicable) to the disposal’s inlet.

14. Dispose of Old Unit:

  • If you replaced an old disposal, dispose of it properly, following your local waste disposal regulations.

Installing a Waste King garbage disposal can be a DIY project for those with some plumbing and electrical experience. However, if you’re unsure about any step or encounter difficulties during installation, it’s advisable to seek the help of a professional plumber or electrician to ensure the job is done safely and correctly.
