Safety First: Essential Precautions

Before embarking on this project, safety should be your top priority. Ensure you have the following tools and materials:

• Safety goggles: Protect your eyes from flying debris.
• Work gloves: Shield your hands from sharp edges.
• Adjustable wrench: For loosening and tightening nuts and bolts.
• Pliers: For gripping and manipulating wires.

Step 1: Powering Down

To avoid electrical hazards, turn off the power to your garbage disposal. Locate the circuit breaker or fuse box and switch off the circuit or remove the fuse that powers the disposal.

Step 2: Disconnecting the Water Supply

Close the water supply valve located under the sink. Disconnect the water lines from the garbage disposal using an adjustable wrench. Place a bucket or bowl underneath to catch any residual water.

Step 3: Detaching the Old Disposal

Use an adjustable wrench to loosen the mounting bolts that secure the garbage disposal to the sink flange. Carefully disconnect the electrical wires from the disposal’s terminal block. Note the position and color coding of the wires for reconnection later.

Step 4: Preparing the New Disposal

Remove the packaging from the new garbage disposal and inspect it for any damage. Connect the electrical wires to the terminal block on the new disposal, following the color coding from the old disposal. Tighten the screws firmly to ensure a secure connection.

Step 5: Installing the New Disposal

Place the new garbage disposal in the sink flange and align the mounting holes. Secure it with the mounting bolts and tighten them using an adjustable wrench.

Step 6: Reconnecting the Water Supply

Reconnect the water lines to the garbage disposal and hand-tighten the nuts. Use an adjustable wrench to fully tighten the connections, but avoid overtightening. Turn on the water supply valve and check for any leaks.

Step 7: Reconnecting the Electrical Wires

Feed the electrical wires through the knockout hole in the sink flange. Connect the wires to the corresponding terminals on the electrical junction box, ensuring proper color matching. Secure the connections with electrical tape.

Step 8: Restoring Power

Turn on the power to the garbage disposal at the circuit breaker or fuse box. Test the disposal by running water through it and pressing the reset button.

In a nutshell: A Job Well Done

Congratulations! You have successfully replaced your hardwired garbage disposal, providing your kitchen with a renewed sense of functionality. By following these steps and exercising caution, you can enjoy a hassle-free and safe installation.
