In this article, we’ll provide you with step-by-step tips on how to remove a Waste King garbage disposal, so you can replace it with a newer and more efficient model.

First things first, it’s important to gather all the necessary tools for the job. You’ll need a pair of pliers, a screwdriver, a hammer, a bucket, and some towels or rags. Additionally, you should have a new disposal unit ready to install once you have removed the old one.

Once you have your tools and new unit in place, it’s time to start the removal process.

Gather the Necessary Tools

Before you can start dismantling your old Waste King garbage disposal unit, you’ll need to gather the necessary tools.

Common mistakes are made when attempting to remove the unit without the proper equipment, so make sure you have the following items on hand before beginning:

  • The first tool you’ll need is a pair of pliers. These’ll be used to loosen and remove the mounting ring that holds the disposal in place.
  • You’ll also need a screwdriver, which’ll be used to remove the mounting screws that attach the disposal to the sink.
  • Additionally, you may need a hammer or mallet to tap the mounting ring loose if it’s stuck.
  • An adjustable wrench is also helpful for loosening and removing the drain pipes.
  • Finally, it’s a good idea to have a bucket or container handy to catch any water or debris that may spill out during the removal process.

Keep in mind that there are alternative methods for removing a Waste King garbage disposal, such as hiring a professional plumber or using a disposal removal tool. However, if you’re up for the challenge, gathering the necessary tools is a great first step towards successfully removing your old unit.

Turn Off the Power Supply

Make sure you shut off the power supply before you go tinkering around with your garbage disposal, as the old adage goes: better safe than sorry.

Here are some steps to follow to ensure that the power supply is turned off before you start:

  1. Locate the circuit breaker box in your home and find the switch that controls the power to your kitchen.
  2. Flip the switch to the ‘off’ position to ensure that no electricity is running to your garbage disposal.
  3. Use a voltage detector to test the wires leading to your garbage disposal to ensure that there’s no electrical current present.
  4. Finally, unplug the garbage disposal from the wall to ensure that there’s no power running to it.

By following these steps, you can be sure that you’ve taken all the necessary precautions to ensure your safety while removing your garbage disposal.

Remember to also follow proper disposal methods for the old unit, such as taking it to a recycling center or calling your local waste management company for guidance.

Disconnect the Plumbing

Now that you’ve ensured your safety, it’s time to disconnect the plumbing and say goodbye to that old, faulty unit.

First, locate the plumbing connections that lead to and from the garbage disposal and use a pipe wrench to loosen the nuts that secure them. Have a bucket ready to catch any water or debris that may spill out.

Alternatively, you can use a pair of pliers to loosen the slip nuts that connect the P-trap to the waste line and the tailpiece of the garbage disposal. This method will allow you to remove the entire P-trap assembly, making it easier to remove the garbage disposal unit.

Once you have removed the garbage disposal, you can now reconnect the plumbing. Start by cleaning the area where the old unit was attached to remove any debris or sealants that may have accumulated.

Then, attach the new mounting assembly to the sink flange, ensuring that it is aligned correctly. You can then reconnect the plumbing using the same nuts and slip joints you removed earlier. Make sure to tighten them enough to prevent any leaks, but not too tight to avoid damaging the pipes.

Finally, test the connections by running water through the sink and checking for any leaks.

With these steps, you can now enjoy a fully functional sink without the hassle of a faulty garbage disposal.

Remove the Mounting Assembly

You may be hesitant to remove the mounting assembly, but it’s necessary to replace your old garbage disposal with a new one.

First, turn off the power to the disposal and remove any remaining mounting screws or bolts.

Next, locate the mounting ring and twist it counterclockwise to release it from the mounting assembly. If you encounter resistance, use a screwdriver or a pair of pliers to help turn the ring.

Once the mounting ring is removed, carefully lift the old disposal off of the mounting assembly.

If the mounting assembly is still in good condition, you can reuse it with your new garbage disposal.

However, if the mounting assembly is damaged or worn out, you may need to consider mounting assembly alternatives.

There are several options available, including mounting assemblies that attach directly to the sink’s drain opening or those that use a bracket system to secure the disposal to the sink.

Be sure to choose a mounting assembly that is compatible with your new garbage disposal and follow the manufacturer’s instructions for installation.

Detach the Garbage Disposal Unit

It’s time to detach the old Garbage Disposal unit from the sink by carefully unscrewing the mounting assembly and gently lowering the disposal down.

To do so, you need to locate the mounting assembly that is attached to the lower part of the disposal. Use a screwdriver to loosen the screws that hold the mounting assembly in place.

Once the screws are loose, the mounting assembly should easily detach from the disposal.

Next, you need to disconnect the electrical wires that are connected to the disposal. Before doing so, turn off the circuit breaker that powers the disposal to avoid any electrical accidents.

Once the power is off, disconnect the wires that connect the disposal to the electrical source.

You can then carefully detach the disposal unit from the mounting assembly and remove it from underneath the sink.

These steps require a bit of patience and precision, but with some home improvement knowledge, you can easily remove the old Garbage Disposal unit and replace it with a new one.

Clean and Inspect the Area

Before installing the new unit, take a moment to clean and inspect the area to ensure that there are no leaks or damage that could affect the new Garbage Disposal’s performance.

Start by unplugging the unit and removing any leftover debris with a towel or rag. Inspect the sink flange and mounting assembly for any visible signs of wear and tear, such as cracks or corrosion. If you notice any damage, it’s best to replace the parts before installing the new unit.

Next, check for leaks by running water through the sink and listening for any unusual sounds. If you notice any leaks, tighten the mounting assembly, the drain line, or the dishwasher connection until it stops.

Finally, turn on the Garbage Disposal and listen for any unusual vibrations or noises. If everything sounds normal, you’re ready to move on to the next step.

By taking the time to clean and inspect the area, you’re ensuring that the new Garbage Disposal will function optimally and won’t cause any damage or leaks in the future.

Tips to Ensure a Smooth Installation:

  1. Clean the area thoroughly to prevent debris from interfering with the new unit’s performance.
  2. Inspect the sink flange and mounting assembly for any visible signs of wear and tear.
  3. Check for leaks and unusual vibrations before installing the new Garbage Disposal to avoid future problems.
