How to Install a Garbage Disposal for the First Time · Step 1 of 7
In this video
Before starting the work, the water supply is turned off using the shutoff valves under the sink. A bucket is placed under the drain pipes to catch water. The old drain assembly, including the two P-traps, is disassembled by hand-loosening the slip nuts. The water supply lines are then disconnected from the old faucet. Using a basin wrench and pliers from underneath the sink, the mounting nuts holding the old faucet are removed. Once loosened, the homeowner pulls the old faucet out from the top of the countertop.

FAQs
What are the essential safety steps to take before and during a first-time garbage disposal installation?
Always turn off the power to the sink area at the circuit breaker first to prevent electrical shock. Wear safety glasses to protect your eyes from debris, and use a bucket and rags to manage water spills. Ensure all electrical connections are secure and properly grounded before restoring power.
Beyond the disposal unit itself, what critical tools and materials are often overlooked but necessary for a smooth installation?
Don't forget plumber's putty for sealing the sink flange, a large bucket and plenty of rags (like HDX Microfiber Rags or WYPALL Towels) for catching residual water, and a good flashlight (like the Panther Vision FLATEYE) to illuminate the workspace. While not always included, you may need a specific InSinkErator 3 ft. Power Cord Installation Kit if your unit isn't pre-wired.
How much time should a beginner set aside for this project, and which part is typically the most challenging?
A first-time garbage disposal installation typically takes 2-4 hours, assuming no major plumbing issues. The most challenging parts are often securing the mounting assembly tightly to the sink to prevent leaks, and making proper, safe electrical connections if you're wiring it yourself rather than just plugging it in.
What are the most common mistakes first-time installers make, and how can I avoid them, especially regarding leaks?
Common mistakes include not applying enough plumber's putty around the sink flange, forgetting to remove the dishwasher knockout plug (if connecting a dishwasher), or not tightening the mounting bolts evenly. To avoid leaks, ensure all connections are hand-tightened and then carefully finished with pliers, and always double-check by running water through the sink for several minutes before buttoning everything up.
