First, shut off the hot and cold water supply by turning the shut-off valves under the sink clockwise. Place a bucket underneath to catch drips. Use a basin wrench or adjustable wrench to disconnect the water supply lines from the old faucet. Unscrew the mounting nuts holding the old faucet in place. Once loose, lift the entire old faucet assembly out from the top of the sink and clean the area.

FAQs

What specific tools are absolutely essential for a beginner to replace a kitchen sink and faucet, beyond standard household items?

A basin wrench, like the Husky 16PL0127, is crucial for reaching and tightening nuts in confined spaces under the sink. You'll also need an adjustable wrench, a 6-in-1 screwdriver (e.g., HDX 120SD12D), and a sturdy bucket (Unger DB02) for catching water. Don't forget plumber's putty and silicone sealant.

What are the most important safety precautions beginners should take when working with water and plumbing under the sink?

Always ensure the main water supply to the sink is completely shut off before disconnecting anything to prevent flooding. Wear safety glasses to protect against drips or debris, and have plenty of old towels and a large bucket readily available for unexpected spills. Be mindful of confined spaces and potential sharp edges.

Is 5 hours a realistic estimated time for a beginner to complete this kitchen sink and faucet replacement project?

While 5 hours is an estimated time, beginners should typically allocate a full day (6-8 hours) to account for potential unexpected issues, learning curves, and trips to the hardware store. Rushing can lead to mistakes and leaks, so take your time and follow each step carefully for best results.

What's a common mistake beginners make during this project, and how can I avoid it or troubleshoot it?

A frequent mistake is not properly sealing the sink's rim or adequately tightening water connections, leading to leaks. Ensure you apply a continuous, even bead of silicone sealant around the sink's edge, and hand-tighten all water supply and drain connections, then give them a final quarter-turn with a wrench. Always perform a thorough leak test after installation.
