Turn off the water supply by turning the shut-off valves clockwise. Open both handles on the faucet to relieve pressure and drain any remaining water from the lines. Place a towel under the connections to catch any drips. Use a wrench to loosen the nuts connecting the old supply lines to the shut-off valves. You may need to use a second wrench to hold the valve body to prevent it from twisting.
Goal: Kitchen Faucet Removal

FAQs
What's the most crucial first step to ensure safety and prevent major issues before starting this tub faucet replacement?
Always locate and turn off the main water supply to your bathroom or entire house before beginning. After turning off the water, open a nearby faucet to relieve any residual pressure in the lines, which prevents unexpected leaks and potential flooding.
Are there any specific tools or materials, beyond the listed adjustable wrench and screwdriver, that I should have on hand for a smoother installation?
Yes, it's highly recommended to have plumber's putty or silicone sealant for a watertight seal around the new valve, and thread seal tape (Teflon tape) for threaded pipe connections. A utility knife can be useful for cutting away old caulk, and a basin wrench might be needed for hard-to-reach nuts.
What is a common mistake beginners make when installing the new valve assembly, and how can I avoid leaks?
A common mistake is not applying enough plumber's putty or sealant, or not properly tightening the connecting nuts. Ensure an even, generous bead of putty is applied around the base of the new valve, and tighten all connections firmly by hand before a final quarter-turn with a wrench, being careful not to overtighten.
The project is rated 'beginner' and estimated at 3 hours, but what if my old faucet components are corroded or stuck?
Corrosion can significantly increase the difficulty and time. If parts are stuck, try applying penetrating oil to the nuts and let it sit for a while before attempting to loosen them. Be prepared for the project to potentially take longer than 3 hours if dealing with very old or stubborn fixtures.
