Disconnect Existing Faucet — Prepare the Mounting Hole

How to Install an In-Sink Air Switch for a Garbage Disposal · Step 2 of 7

Now, disconnect all parts of the old faucet. Start by using a crescent wrench to unscrew the water supply lines from the base of the old faucet. Next, unclip the spring clip that connects the clevis strap to the pivot rod of the drain stopper assembly. Unscrew the two plastic mounting nuts that hold the faucet body to the underside of the countertop. This can be awkward, so work in whatever order is most accessible. Once everything is disconnected, lift the old faucet straight up and out of the sink.
Goal: Remove old faucet
- Use two wrenches when disconnecting water lines—one to hold the shut-off valve steady and one to turn the nut—to prevent twisting and damaging the plumbing.

FAQs
The project is rated 'beginner' and takes 3 hours. Is this accurate, and what's the most challenging part for a novice?
Yes, 'beginner' is fair, but careful electrical safety is crucial. The most challenging part is often drilling the initial hole in your sink or countertop, ensuring it's the correct size and location without damaging the surface. Take your time with measurements and use the appropriate drill bit for your material.
Since this involves electricity and water under the sink, what are the most critical safety precautions I need to take?
Always start by turning off the power to the garbage disposal circuit at your main electrical panel to prevent shock. Double-check with a non-contact voltage tester before proceeding. Ensure all electrical connections are secure and that the power control module is mounted in a dry, accessible location to avoid water exposure.
The materials list includes a 'QuietWarmth Power Module with Built-in GFCI TH-POWER'. Is a GFCI module essential, and can I use a standard wall outlet?
Yes, a GFCI (Ground Fault Circuit Interrupter) module is highly recommended for safety in wet environments, providing critical shock protection. You will plug the module into a standard wall outlet, but the module itself (or the outlet it plugs into) *must* provide GFCI protection for the disposal circuit. This is a vital safety feature.
What's the most common mistake beginners make, and how can I troubleshoot if my air switch doesn't work after installation?
A common mistake is not fully seating the flexible air tube, leading to a weak or unresponsive button. If the switch doesn't work, first confirm the disposal power is on at the breaker, then check the air tube connections at both the button and the power module for tightness. Also, verify all electrical connections are secure and the power module is receiving power.
