Place a bowl under the water supply lines to catch any residual water. Using an adjustable wrench and channel lock pliers, first disconnect the hot and cold supply lines from the shut-off valves. Then, reach up under the sink and disconnect the supply lines from the base of the old faucet. A basin wrench will be needed to loosen and remove the mounting nuts that secure the old faucet to the sink. Once all connections are loose, pull the old faucet assembly up and out from the top of the sink.
Goal: Completely remove the existing faucet from the sink
- A basin wrench is highly recommended for reaching the faucet mounting nuts in the tight space behind the sink basin.

FAQs
What specialized tools should I definitely have for removing the old faucet and installing the new one, especially if I'm a beginner?
A basin wrench, like the TEKTON WRN92004, is crucial for reaching and loosening nuts in tight spaces under the sink. An adjustable wrench is also essential for connecting supply lines. Additionally, having a bucket like the Unger DB02 will help catch any residual water.
What's the very first thing I need to do to ensure safety and prevent water damage before starting the faucet replacement?
Always start by shutting off the hot and cold water supply valves directly under the sink. If those don't work or don't exist, you'll need to turn off the main water supply to your house. Once the water is off, open the old faucet to relieve any remaining pressure in the lines.
How can I prevent leaks after installing the new faucet, which seems to be a common issue for DIYers?
Ensure all connections, especially the supply lines, are hand-tightened first, then given a quarter to half turn with an adjustable wrench for a snug fit. Use plumber's putty or silicone sealant around the base of the new faucet as directed by the manufacturer to create a watertight seal with the sink deck.
This project is rated "beginner" with an estimated time of 3 hours. Is that realistic, or should I budget more time if it's my first time?
While rated beginner, 3 hours is an estimate for someone with basic DIY experience and no major issues. If it's your first time or if you encounter seized or hard-to-reach nuts on the old faucet, plan for 4-6 hours. Take your time, read all instructions carefully, and don't rush the process.
