In this video
Before starting the removal process, turn off the water supply to the sink. Locate the hot and cold shutoff valves under the sink and turn them clockwise until they stop. After shutting off the water, open the faucet taps to release any remaining pressure and drain the water from the lines. Place a bucket underneath the plumbing connections to catch any water that spills during disconnection.
Goal: Prepare for sink removal
- Ensure the water is completely off before disconnecting any plumbing. Test by turning on the faucet; no water should flow.

FAQs
What critical safety precautions should I take before starting the garbage disposal installation?
Always begin by turning off the power to the disposal circuit at your home's breaker panel and shutting off the cold water supply valve under the sink. This prevents accidental electrical shock or water leaks during the process. Place a bucket under the P-trap to catch any residual water when disconnecting pipes.
Beyond pliers, what other tools or materials are absolutely essential for a successful new garbage disposal installation?
You'll likely need a wrench, possibly an Allen wrench (often provided with new disposals for mounting bolts), and a screwdriver. Don't forget plumber's putty for sealing the sink flange and a reliable bucket to manage water during disconnection.
After installation, I notice a leak around the connections. What are the most common causes and how can I fix them?
Leaks often stem from loose connections, an improperly seated P-trap, or insufficient plumber's putty around the sink flange. First, ensure all pipe connections are securely hand-tightened, then given a quarter turn with pliers. If the leak is at the flange, you may need to reapply plumber's putty.
As a beginner, how realistic is the 3-hour estimate, and what makes this project suitable for a DIY novice?
The 3-hour estimate is realistic for many beginners who follow instructions carefully and have basic tool familiarity. Its beginner-friendly nature comes from the clear, sequential steps and the limited number of specialized tools required. Taking your time and double-checking each step is key to staying within this timeframe.
