Removing the Old Garbage Disposal Unit
Before installing the new unit, you need to remove the old one. Follow these steps:
- Turn off the power to the disposal unit at the circuit breaker.
- Place a bucket under the sink to catch any water or debris.
- Disconnect the electrical wires from the disposal unit. Use a screwdriver to remove the wire nuts and separate the wires.
- Disconnect the drain pipe from the disposal unit. Use an adjustable wrench to loosen the slip nut and remove the pipe.
- Remove the mounting assembly. Use a screwdriver to remove the screws holding the mounting ring to the sink.
- Remove the old disposal unit. Hold the unit steady and twist it counterclockwise to detach it from the mounting assembly.
Once the old unit is removed, clean the area thoroughly to ensure a smooth installation of the new unit.
🛠️ Note: If you encounter any difficulties during the removal process, consult the manufacturer's instructions or seek professional help.
Installing the New Garbage Disposal Unit
Now that the old unit is out, it's time to install the new one. Follow these steps:
- Prepare the mounting assembly. Apply a thin layer of plumber's putty around the mounting ring and place it on the sink flange.
- Insert the new disposal unit into the mounting assembly. Align the unit with the mounting ring and twist it clockwise to secure it in place.
- Connect the drain pipe. Attach the drain pipe to the disposal unit using the slip nut and tighten it with an adjustable wrench.
- Connect the electrical wires. Match the wires from the new disposal unit to the corresponding wires from the power source. Use wire nuts to secure the connections.
- Test the unit. Turn on the power at the circuit breaker and test the disposal unit to ensure it is working correctly.
If everything is connected properly, your new garbage disposal unit should be up and running smoothly.
🛠️ Note: Ensure that all connections are secure and there are no leaks before turning on the power.
