Prepare for the Replacement

Before diving into the installation process, it’s important to gather the necessary tools and materials. Ensure you have a new Badger 100 or a suitable replacement model, a screwdriver, an adjustable wrench, plumber’s putty, a bucket or towels for catching water, and a disposal installation kit (if required). Familiarize yourself with the manufacturer’s instructions and safety precautions to ensure a successful installation.

Disconnect the Old Garbage Disposal

Start by disconnecting the power supply to the garbage disposal unit. Locate the circuit breaker panel and switch off the power dedicated to the disposal. Next, disconnect the disposal unit from the sink’s drainpipe. Loosen the metal clamp connecting the disposal to the drainpipe using a screwdriver or adjustable wrench. Remove the disposal unit carefully, allowing any remaining water to drain into a bucket or towels.

Remove the Mounting Assembly

Once the old disposal unit is removed, detach the mounting assembly from the sink’s underside. Loosen the mounting bolts securing the assembly using a screwdriver or wrench. Gently lower the assembly and remove it from the sink. Clean any debris or old putty from the sink flange to ensure a proper seal with the new unit.

Install the New Garbage Disposal

Following the manufacturer’s instructions, assemble the new Badger 100 or replacement unit. Apply a thin, continuous ring of plumber’s putty around the sink flange. Carefully insert the flange into the sink’s drain opening, pressing it firmly into place. From below the sink, position the mounting assembly over the flange, aligning the mounting bolts with the corresponding holes. Secure the assembly by tightening the mounting bolts using a screwdriver or wrench.

Connect the Plumbing

Attach the discharge tube to the disposal unit’s outlet, ensuring a snug fit. Use a screwdriver or wrench to tighten any necessary connectors. Connect the other end of the discharge tube to the sink’s drainpipe, securing it with a metal clamp or appropriate connector. Double-check all connections to ensure they are tight and leak-free.

Test and Finalize

With the installation complete, it’s time to test the new garbage disposal. Restore power to the unit by switching on the dedicated circuit breaker. Run water into the sink and turn on the disposal, checking for any leaks or unusual noises.

Dispose of small food scraps gradually to ensure the unit is operating smoothly. If everything looks and sounds good, congratulate yourself on a successful replacement!


Replacing a Badger 100 garbage disposal doesn’t have to be a daunting task. By following this step-by-step guide and utilizing new ideas and advice, you can confidently upgrade your kitchen and enjoy the benefits of a functional and efficient garbage disposal. Remember to gather the necessary tools, disconnect the old unit, remove the mounting assembly, install the new garbage disposal, connect the plumbing, and thoroughly test the system.

With proper installation and regular maintenance, your new disposal unit will enhance your kitchen experience and simplify your daily cleanup routine.
