In this video

Before you begin, make sure to shut off the electrical power supply to the garbage disposal unit at the breaker. Unplug the disposer from the wall outlet if it has a plug. Also, turn off the water supply to your sink. Place a bucket or pan underneath the garbage disposal and remove the drain pipe and dishwasher drain tube if present.

Goal: Prepare for Installation

  • Always disconnect the power supply before working on any electrical appliance.
  • Use a bucket or pan to catch any water that may spill during the process.

FAQs

Do I really need a specific 1-5/16 inch hole saw for the air switch button, or can I use a different size drill bit?

Using the recommended 1-5/16 inch hole saw is crucial for a clean, precise cut and a snug fit for the air switch button. An incorrect size could lead to a loose fit, potential water ingress, or difficulty in securing the button properly. While other methods might exist, the hole saw provides the best result for durability and safety.

What are the most important safety precautions I need to take before starting this installation, especially since it involves electrical components near water?

Always turn off the power to your garbage disposal circuit at the breaker before beginning any work, and confirm it's off with a non-contact voltage tester. Ensure your work area under the sink is completely dry, and after installation, thoroughly check for any leaks around the new switch and existing plumbing connections before restoring power.

My air switch button is installed, but the garbage disposal isn't turning on when I press it. What should I check first?

First, verify that the power control module is plugged into a functioning outlet and the garbage disposal is securely plugged into the module. Next, check that the air tube is firmly connected to both the air switch button under the sink and the power control module. A kinked or disconnected air tube is a common issue.

Is there an alternative to drilling a hole in my sink deck if I'm hesitant to do so?

Yes, if you have an existing unused pre-drilled hole in your sink deck (like for a soap dispenser or old sprayer), you can often use that. Alternatively, some air switch kits offer options for mounting directly into the countertop instead of the sink, or you can purchase a separate countertop-mounted button that doesn't require drilling into the sink.
