Disconnect the dishwasher drain hose from the garbage disposal. Use a flathead screwdriver as a lever to twist the mounting ring on the garbage disposal, releasing it from the sink flange. Lower the disposal and set it aside. To remove the old strainers, use a screwdriver to loosen the three mounting screws underneath. Pry off the C-shaped retaining ring with the screwdriver, and then push the old strainers out from the top of the sink.

FAQs
What are the most critical safety precautions I must take before starting this project?
Always turn off the power to the garbage disposal circuit at your electrical panel first to prevent electrical shock. Additionally, shut off the water supply to your sink to avoid unexpected leaks when disconnecting the old unit. Double-check both power and water are off before touching any wires or pipes.
Do I really need a special basin wrench for this installation, or can I use regular tools?
While some might manage with pliers and screwdrivers, a basin wrench (like the Husky 16PL0127) is highly recommended. Its specialized design allows you to easily reach and loosen the old mounting nuts in the tight space under the sink. This tool significantly simplifies the removal process and saves a lot of frustration.
What are the most common reasons for leaks after installing a new garbage disposal?
Leaks commonly occur if the plumber's putty around the sink flange wasn't applied correctly, creating an imperfect seal with the sink basin. Another frequent cause is improperly tightened or sealed connections at the discharge pipe or the dishwasher drain hose. Ensure all connections are secure and sealed properly during assembly.
What should I do if my new garbage disposal doesn't turn on after installation?
First, recheck the circuit breaker to confirm the power is on for that outlet. Then, verify all electrical connections are secure and the wire nuts are properly twisted and connected. Many disposals also have a small red reset button on the bottom; try pressing this before troubleshooting further.
