Using an adjustable wrench, carefully loosen the nuts connecting the flexible water supply lines to the shutoff valves. Hold the valve with one hand or another wrench to prevent it from twisting. Once the nuts are loose, unscrew them by hand and pull the lines away from the valves, directing any draining water into the bucket.
Goal: Disconnect water supply
- Be careful not to damage the shutoff valves or the pipes in the wall. If a connection is corroded, apply penetrating oil.

FAQs
Do I really need specialized tools like a basin wrench to replace my bathroom faucet?
While an adjustable wrench can sometimes work, a basin wrench (like the Husky or TEKTON models mentioned) is highly recommended. It's specifically designed to reach and loosen/tighten mounting nuts in the tight, awkward spaces under your sink, making the job significantly easier and less frustrating for beginners.
What should I do if the water shut-off valves under my sink are stuck or won't turn off completely?
If the under-sink valves are stuck or faulty, you'll need to locate and turn off the main water supply to your entire house before proceeding. If you're uncomfortable doing this or if the main valve is also problematic, it's best to call a professional plumber to avoid potential water damage.
How can I ensure I don't have any leaks after installing my new faucet and drain?
To prevent leaks, make sure all threaded connections are hand-tightened first, then snugged with a wrench, avoiding overtightening which can crack parts. Always use plumber's tape (Teflon tape) on threaded supply line connections and plumber's putty or the provided gasket for the drain assembly to create a watertight seal.
Is it okay to reuse my old water supply lines with the new faucet, or should I replace them?
It is strongly recommended to replace old water supply lines with new ones when installing a new faucet. Old lines can degrade, become brittle, or leak after being disturbed, even if they look fine. Many new faucets come with fresh supply lines, or they are inexpensive to purchase separately.
