Install a Garbage Disposal with an Air Switch

Project Overview

• 💡 Plumbing expert Richard Trethewey assists homeowner Emily in installing a garbage disposal in her recently renovated kitchen, which lacked this essential appliance.
• 🎯 The installation focuses on using a safe and convenient air switch for operation, leveraging existing electrical rough-ins without needing a traditional wall switch.

Garbage Disposal Features & Mounting

• ⚙️ The chosen unit is a 3/4 horsepower continuous feed garbage disposal, a common modern type that grinds food while running.
• 🛠️ A standard mounting flange assembly is used, requiring the removal of the existing basket strainer and securing the new flange with plumber's putty to the sink.
• 💧 Once mounted, the disposal's elbow can be adjusted for plumbing connections, and a dedicated port allows for the dishwasher drain to be connected securely.

Air Switch Operation & Benefits

• ⚡ The air switch provides a safe alternative to traditional electrical switches by keeping electricity away from the sink area.
• 🌬️ It operates by plugging into an outlet, with the disposal plugging into the switch unit; a flexible air tube connects to a countertop button, which sends a puff of air to activate the disposal.
• ✅ This method offers convenience and enhanced safety, as there's no direct electrical connection at the point of interaction near water.

Installation Process Highlights

• 🔩 The process involves excavating existing plumbing, removing the old basket strainer, and then installing the new disposal's flange assembly onto the sink.
• 💎 A critical step is drilling into the stone countertop to install the air switch button, which Richard notes can be the most challenging part.
• 🔌 Final steps include connecting the air tube, making all drain connections, and attaching the dishwasher discharge before a final operational test with running water.
