Identifying Your Disposal Model
Finding the model number of your existing Waste King garbage disposal is crucial. It ensures you order the exact replacement part, avoiding compatibility issues. This usually involves checking a sticker on the unit itself or referring to the appliance’s original documentation.
- Locate the model number sticker: This is often found under the disposal unit or on the top.
- Check your owner’s manual: If you still have it, the model number should be printed clearly.

Disconnecting the Old Waste King Disposal
This section details how to safely and efficiently disconnect the old Waste King garbage disposal from your plumbing and electrical systems. This involves carefully separating the various connections, ensuring you don’t cause any damage to the surrounding pipes or wiring.
Disconnecting the Plumbing
- Place a bucket under the disposal to catch any remaining water.
- Use the basin wrench to loosen the slip nuts connecting the drain pipes to the disposal.
- Carefully disconnect the drain pipes from the disposal’s inlet and outlet.
- Disconnect the garbage disposal drain from the sink drain flange.
Be prepared for some water spillage during this step. Working slowly and methodically will minimize the mess. Having rags or towels handy is always a good idea.
Disconnecting the Electrical Wiring
- Carefully disconnect the electrical wires from the disposal’s terminals. Make a note of how each wire is connected for easier reconnection later.
- Use electrical tape to cover the exposed wires to prevent shorts.
Electrical work should only be attempted if you’re comfortable working with electrical wiring. If unsure, consult a professional electrician. Safety is paramount. A simple mistake can lead to fire hazards.
Removing the Mounting Assembly
- Loosen the mounting screws holding the disposal in place, usually located under the unit.
- Lower the disposal carefully from under the sink cabinet.
The disposal might be heavier than it seems. It’s always better to have a helper to assist with lifting and maneuvering the heavy unit. This prevents accidents and injuries.
Installing the New Waste King Garbage Disposal
This is the core section where you’ll learn the step-by-step process of installing your new Waste King garbage disposal. We’ll cover attaching the plumbing, connecting the electrical wiring, and finally securing the disposal under the sink.
Connecting the Plumbing
- Connect the drain pipes to the new disposal’s inlet and outlet, using the slip nuts.
- Tighten the nuts using the basin wrench, ensuring a secure but not over-tightened connection.
- Connect the garbage disposal drain to the sink drain flange, ensuring a tight seal.
Make sure all connections are tight to prevent leaks. It’s often better to slightly under-tighten and then check for leaks before tightening fully.
Connecting the Electrical Wiring
- Reconnect the electrical wires to the disposal’s terminals, matching them to the previous configuration. Consult the wiring diagram included with your new disposal for detailed instructions.
- Secure the wires with wire nuts and ensure a proper connection.
Double-check the wire connections to ensure they are secure and correctly wired. Incorrect wiring can lead to malfunction and safety hazards.
Securing the Mounting Assembly
- Carefully position the new disposal under the sink.
- Tighten the mounting screws to secure the disposal in place.
Ensure the disposal is level and stable before tightening the screws fully. This ensures proper functionality and longevity of the appliance.
Testing and Troubleshooting
This final step covers testing the new Waste King garbage disposal to ensure it’s working correctly and troubleshooting any issues that may arise. It’s a crucial step to confirm a successful installation and address any potential problems early on.
Testing the Disposal
- Turn on the power to the garbage disposal at the circuit breaker.
- Run some cold water and turn on the disposal. Listen for any unusual noises.
- Check for leaks around all the connections.
Always start with a small amount of waste to test the functionality. It’s better to test gradually than to overload the system immediately.
Troubleshooting Common Issues
- Disposal won’t turn on: Check the power supply, circuit breaker and wiring connections.
- Disposal hums but doesn’t grind: A jammed impeller might be the issue. Use tongs to remove any obstructions.
- Leaks around the disposal: Check for loose connections and retighten them. If necessary, replace the seals.
Addressing issues promptly can prevent further damage. If you cannot identify or resolve the problem, consulting a professional plumber is always recommended.
