Disconnect the supply lines from the faucet. For the supply lines with metal nuts, use a basin wrench to loosen them from the faucet. If there are plastic nuts on the faucet connections, you may need to use a special tool or, with a small cut, a piece of PVC pipe will often work. Turn the nuts counter-clockwise to loosen and remove them.

FAQs
What essential tools do I absolutely need for this faucet replacement, beyond a standard adjustable wrench?
While an adjustable wrench is useful, a basin wrench is highly recommended for reaching and loosening the mounting nuts under the sink in tight spaces. You'll also likely need a small bucket or towels to catch residual water, and potentially a utility knife for cutting old sealant if present. Having these tools will significantly ease the installation process.
What are the most crucial safety precautions I should take before starting to remove the old faucet?
Always start by turning off both the hot and cold water supply valves directly under the sink to prevent flooding. After shutting off the water, open the old faucet handles to release any remaining pressure in the lines. If your sink has a garbage disposal, unplug it from the wall outlet to avoid accidental activation while working underneath.
How difficult is this kitchen faucet replacement for someone with limited DIY experience, and what's a realistic time estimate?
This project is rated as beginner-friendly, and with the right tools and preparation, it can typically be completed within 2 hours. The main challenges usually involve working in tight, awkward spaces under the sink and sometimes dealing with stubborn, corroded fittings. Patience and following the steps carefully are key to a smooth installation.
What are common mistakes to avoid during installation, and how can I ensure there are no leaks after I'm done?
A common mistake is overtightening or cross-threading the water supply lines; always hand-tighten first, then use a wrench for a final quarter-turn. To prevent leaks, ensure all connections have appropriate washers or plumber's tape/sealant where indicated. After installation, slowly turn the water supply back on and meticulously check every connection for even the slightest drip, tightening carefully if needed.
