Turn Off Water

Before diving into the thick of things, it’s essential to twist the valves under the sink clockwise to cut off the water supply. This simple act is a safeguard against accidental flooding that could turn your renovation project into a costly catastrophe.

In the admittedly rare case where these valves are missing or broken, your next stop is the main water shut-off for the entire household. Carefully locating and switching this off will prevent any unwelcome geysers as you proceed with replacing the faucet.

Remember, a dry workspace is a safe workspace and gives you the clean slate needed for a successful installation.

Remove the Old Faucet

Begin by cautiously placing a bucket or towel under the sink area to catch any residual water that may escape during the process. Arm yourself with a basin wrench, which is designed to tackle the tight spaces and awkward angles found under the sink.

Proceed to disconnect the water supply lines—but do remember, righty-tighty, lefty-loosey doesn’t hold when you’re upside down; mirror the movement to your orientation. With the lines detached, address the mounting nuts that secure the faucet to the sink.

Expect some resistance from corrosion or hard water deposits, embracing the challenge with penetrating oil if needed. Gently wiggle the faucet to free it, keeping in mind the goal is to remove it, not remodel the entire counter. Safeguard the sink’s finish by covering the jaws of your wrench with tape, preventing scratches or scrapes.

After lifting the faucet out, clean the area to ready it for the new installation, ensuring a clean canvas for your next masterpiece.

Position the New Faucet

With the old faucet out of the way, the stage is set for a fresh start. Begin by ensuring the sink surface is clean and dry, setting the stage for a secure installation.

Place the new faucet into the mounting holes. For a snug fit, align it perfectly to ensure the handles and spout are facing the correct direction—toward the user and over the sink respectively.

On the underside, attach any provided hardware, usually a washer and mounting nuts, to hold the faucet firmly in place. Tighten these nuts by hand first to secure the positioning, then use a basin wrench to ensure they are snug, but take care not to overtighten and risk damaging the new hardware.

Proper alignment is not just a matter of aesthetics; it is crucial for the seamless operation of your new bathroom centerpiece.

Connect Water Supply Lines

Securing the water supply lines to your new faucet is crucial. Start by threading the lines through the designated holes, ensuring a snug fit without over-tightening to avoid stripping the threads.

Use plumber’s tape on the connections if recommended by the manufacturer for a tight seal. Tighten the nuts by hand, and then give them a final snug with a wrench—but don’t overtighten, as this could damage the nuts or lines. Remember, gentle firmness is key in preventing future leaks.

After securing the supply lines, the path is set for a rigorous final inspection.

Check for Leaks

After installation, vigilance is key. Test your work by slowly turning the water back on and observing the new faucet for any water seeping through connections. This step is crucial; a small drip can quickly evolve into costly damage.

Use a dry paper towel; it’ll reveal even the most discreet moisture. Search both above the sink where the faucet meets the countertop and below, scrutinizing all connections to the water supply lines. If you do spot a leak, don’t panic. Shut off the water again and slightly tighten fittings, but avoid over-tightening which can warp or crack materials.

Remember, patience and precision now can save a flood of troubles later.
