Project Snapshot

Replacing a leaky faucet involves disconnecting water lines, removing the old fixture, and installing a new faucet assembly. This project requires moderate DIY skills, a few common tools, and close attention to avoid water damage. Completing the job restores function and style to your sink area while helping conserve water and saving money on your bills.

Tools and Materials

To replace your faucet, gather an adjustable wrench, pipe wrench or basin wrench, a bucket or towel to catch drips, plumbers tape, and possibly some penetrating oil for stubborn connections. Make sure to purchase a new faucet kit that matches your sink’s configuration. You might also need supply line hoses if your old ones are worn, as well as a flashlight for illuminating tight spaces under the sink.

Step-by-Step Instructions

Begin by shutting off the water supply to your sink using the valves beneath it. Place your bucket or towel below to catch any residual water. Use your wrench to disconnect the hot and cold supply lines from the faucet. Carefully loosen and remove the nuts or brackets securing the old faucet to the sink or countertop. Lift out the old faucet assembly and clean the sink area thoroughly where the new one will sit. Lay the new faucet in place, attaching with the provided hardware. Connect the supply lines to the new faucet, using plumber’s tape for a secure seal. Turn the water supply back on and check for leaks, tightening fittings as needed. Finally, test all faucet functions to ensure smooth operation.

From the Toolbox

Once I helped a friend replace a kitchen faucet that had leaked for months. We discovered the old fixture was nearly fused to the sink from years of mineral buildup. A little patience, some penetrating oil, and the right wrench made all the difference. That sense of accomplishment—and the instant improvement—was worth every minute spent under the sink.

Top 5 Mistakes

Skipping the water shutoff and flooding the cabinet is a common error. Failing to match the new faucet to the sink configuration leads to frustrating returns. Reusing old supply lines can cause future leaks. Forgetting plumber’s tape increases risk of drip at fittings. Overtightening connections can crack parts or strip threads.

Tool and Material Recommendations

Invest in a quality adjustable wrench and a basin wrench to make tight spots easier to reach. Always buy faucet brands with good customer support and clear installation instructions. Replace old or brittle hoses while you’re at it—Braided stainless steel supply lines offer extra peace of mind. Plumber’s tape and a reliable flashlight should always be part of your toolkit for plumbing fixes.

Quick Tips and Hacks

Label your supply lines before disconnecting to keep hot and cold straight. Have extra towels ready for accidental drips. Apply a little penetrating oil to stuck nuts for easier removal. Always read the faucet instructions before starting—every model has special steps. Tighten fittings snugly but don’t overdo it to avoid damage.
