DIY: How to Replace and Install a Bathroom Sink Faucet

Introduction

Replacing a bathroom sink faucet can seem daunting, but with just a couple of tools and some guidance, you can do it yourself in under an hour. This tutorial will walk you through the steps to shut off the water, remove the old faucet, install a new one, and check for leaks. By completing this project yourself, you can save money and gain a sense of accomplishment.

Step 1: Shut Off Water Supply

Before starting any work, ensure the water supply is turned off to avoid any spills.

• Locate the shut-off valves under the sink.
• Turn the valves clockwise until they are fully closed.
• If you don’t have shut-off valves, you may need to turn off the main water supply for your home.

Step 2: Remove the Old Faucet

Now that the water is off, you can safely remove the old faucet.

• Use an adjustable wrench to loosen and disconnect the water supply lines from the faucet.
• Unscrew the mounting nuts that hold the faucet in place. You may need tongue and groove pliers for better grip.
• Once the nuts are removed, lift the old faucet out of the sink.

Step 3: Install the New Faucet

With the old faucet removed, it’s time to install the new one.

• Position the new faucet in the sink hole.
• Secure it by tightening the mounting nuts from underneath the sink. Ensure it is aligned properly.
• Reconnect the water supply lines to the new faucet, tightening them with an adjustable wrench.

Step 4: Replace the Drain (Optional)

If you plan to replace the drain, follow these steps.

• Remove the old drain by unscrewing the drain locknut beneath the sink.
• Clean the sink hole thoroughly to ensure a good seal for the new drain.
• Insert the new drain into the sink and secure it with the locknut.

Step 5: Install the New Drain

Now that the old drain is removed, install the new one.

• Apply plumber's putty around the drain flange to create a watertight seal.
• Insert the new drain into the sink hole and press it down firmly.
• From underneath the sink, tighten the locknut to secure the drain in place.

Step 6: Check for Leaks

After installation, it’s crucial to ensure everything is functioning correctly.

• Turn the water supply back on slowly.
• Open the faucet and let the water run for a few moments.
• Inspect all connections for any signs of leaks. If you see any, tighten the connections as necessary.
