With the old faucet removed, you will likely see residue from old plumber's putty. Use a plastic scraper or a putty knife to carefully scrape all of the old, hardened putty off the sink surface. Be careful not to scratch the sink. After scraping, use a sponge with some water or a mild cleaner to wipe down the entire area, ensuring it is clean and free of debris for the new faucet installation.

Goal: Prepare sink surface for new faucet

  • An old credit card or gift card makes a great scraper that is less likely to scratch a porcelain sink.

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.
