With the water off, proceed to remove the old faucet. From underneath the sink, use a basin wrench or the specific tool provided with the old faucet to loosen and unscrew the large mounting nut holding the faucet in place. You may also need to disconnect the hot and cold water supply lines from the shut-off valves if they are not being replaced. Once all mounting hardware and hoses are disconnected, go to the top of the sink and carefully lift the entire old faucet assembly up and out of the mounting hole.
Goal: Disconnect and remove the old faucet from the sink.

FAQs
Why is a basin wrench listed as a required tool for this project?
A basin wrench is crucial because it's specifically designed to reach and loosen the mounting nuts that secure the faucet from underneath the sink. These nuts are often in very tight, awkward spaces where a regular adjustable wrench simply cannot fit or get enough leverage.
What should I do if the old faucet's mounting nuts are corroded and won't budge?
First, try applying a penetrating oil to the corroded nuts and let it sit for 15-30 minutes to help break down the rust. If they still won't turn, you may need to use a small hacksaw or a specialized nut splitter designed for plumbing to carefully cut through the nuts. Always wear eye protection when doing this.
Is 3 hours a realistic time estimate for someone who's never replaced a faucet before?
While 3 hours is a good estimate for an experienced DIYer, beginners should budget a bit more time, perhaps 4-6 hours. This allows for unexpected challenges like stubborn old parts, cleaning time, and carefully familiarizing yourself with the new faucet's instructions without rushing.
After installing the new faucet and turning the water back on, I have a small leak under the sink. What should I check first?
The most common culprits for leaks are loose supply line connections or improperly tightened mounting nuts. Gently but firmly tighten these connections with your adjustable wrench. If the leak persists, you may need to disassemble the connection, inspect the washers/gaskets, and reassemble with plumber's tape or a fresh application of plumber's putty if applicable.
