In this video
Place a bucket directly under the P-trap to catch any trapped water. Use channel-lock pliers to loosen the two large slip nuts that connect the curved P-trap to the sink's drain tailpiece and the drain pipe in the wall. Once loose, you can finish unscrewing them by hand and remove the P-trap, emptying any water into the bucket. Next, unscrew the connectors for the hot and cold water supply lines from the shutoff valves, allowing them to drain into the bucket as well.
Goal: Disconnect all plumbing from the wall

FAQs
What is the most critical safety step I must take before starting to replace my garbage disposal?
Always disconnect power to the disposal at your home's circuit breaker before touching any wires or plumbing. This prevents electrical shock and injury. Verify the power is off by trying to turn on the disposal switch or a nearby kitchen light before you begin work.
Are the specified tools like Channellock pliers and an adjustable wrench truly necessary, or can I get by with standard household tools?
The specified tools are highly recommended for ease and effectiveness. Channellock pliers provide a strong grip for stubborn P-trap nuts, and an adjustable wrench is crucial for securing the mounting ring firmly. While you might manage with other tools, these will make the job much smoother, especially for a beginner.
What is the most common mistake beginners make, and how can I avoid leaks after installation?
The most common mistake is not properly sealing the sink flange or tightening connections sufficiently. Ensure you use a generous roll of plumber's putty around the sink flange before installation. After the unit is installed and connected, fill the sink with water and check thoroughly for any drips or leaks around all connections before restoring full power.
Is the estimated 3-hour time frame realistic for someone who has never replaced a garbage disposal before?
Three hours is a reasonable estimate for a beginner, assuming you have all tools and materials ready and experience no unexpected issues. Your first time might take longer as you familiarize yourself with the process. Allocating an extra hour or two allows for troubleshooting without feeling rushed.
