In this video
Place a bucket under the drain pipes to catch any residual water. First, disconnect the dishwasher drain hose from the disposal by loosening the metal clamp. Next, unscrew the large slip nut that connects the P-trap drain assembly to the disposal's discharge outlet. You may need pliers if it's too tight to loosen by hand.
Goal: Detach Drain Pipes
- Having a bucket and some old towels ready will help manage any water that spills from the pipes.

FAQs
What are the absolute must-do safety precautions before I start replacing my garbage disposal?
Always begin by turning off the power to the disposal circuit at your home's breaker box and verifying with a non-contact voltage tester. Additionally, turn off the hot and cold water supply valves under the sink to prevent accidental flooding while working on plumbing connections.
Do I need special tools to replace a garbage disposal, or can I get by with basic household items?
While standard tools like a screwdriver (e.g., HDX 6-in-1) and pliers (e.g., Southwire diagonal cutting pliers) are essential, a garbage disposal wrench (often included with new units or sold separately) is highly recommended for easy removal of the old unit. You'll also need a bucket (like the Unger 6 Gal.) to catch residual water and plumber's putty for sealing.
The project is rated as 'beginner' and '3 hours.' Is this realistic for someone with limited DIY experience?
Yes, this project is generally beginner-friendly if you carefully follow the step-by-step guide and prioritize safety. The 3-hour estimate is reasonable for someone prepared with all tools and parts, but unexpected plumbing challenges or a particularly stubborn old unit could extend the time slightly.
What's the most common mistake that leads to leaks after installing a new garbage disposal, and how can I prevent it?
The most frequent cause of leaks is improper sealing of the sink flange with plumber's putty. Ensure you apply a generous, continuous bead of putty under the flange before seating it in the sink and tighten the mounting bolts evenly. Also, double-check that all drain connections, especially the discharge pipe and dishwasher drain, are tightly secured with their gaskets or rubber washers.
