Step-by-Step Guide: Replacing Your Garbage Disposal

Step 1: Preparation

Start by turning off the power to the garbage disposal at the circuit breaker. Use a circuit tester to ensure there’s no electricity running to the unit. Once confirmed, unplug the disposal from the electrical outlet.

Step 2: Disconnect the Old Disposal

With the power off, remove the drain pipe and dishwasher hose from the old garbage disposal. Loosen the mounting ring, and carefully twist the disposal counterclockwise to detach it from the mounting bracket. Lower the unit and remove it from under the sink.

Step 3: Install the New Garbage Disposal

Follow the manufacturer’s instructions to install the new garbage disposal. Use plumber’s putty around the sink flange to create a watertight seal. Secure the disposal to the mounting bracket, and reattach the drain pipe and dishwasher hose.

Step 4: Connect the Electrical Wiring

Carefully connect the electrical wires from the disposal to the corresponding wires in the electrical box. Use electrical tape to secure the connections, and carefully tuck the wires back into the box.

Step 5: Test the New Garbage Disposal

Before completing the installation, run a quick test to ensure everything is working correctly. Plug the disposal back into the electrical outlet and turn the power on at the circuit breaker. Run water into the sink and switch on the disposal to check for any leaks or unusual noises.

Step 6: Finishing Touches

If the test is successful, turn off the disposal and unplug it again. Make any necessary adjustments and tighten connections if needed. Clean up any debris and ensure everything is properly secured and sealed.

Conclusion:

Replacing a garbage disposal is a manageable DIY project that can save you time and money. Armed with the right tools and our step-by-step guide, you’ll be able to tackle this task with confidence.
