Removing the Old Faucet

Tools You’ll Need:

Before you begin, make sure you have the following tools handy:

  • Adjustable wrench
  • Basin wrench
  • Screwdriver (Phillips and flathead)
  • Plumber’s tape
  • Bucket or towel to catch any water drips

Step 1: Shut off the Water Supply

To avoid any water leakage during the replacement process, you need to turn off the water supply to the kitchen faucet. Look for the shut-off valves under the sink and close them by turning them clockwise.

Step 2: Disconnect the Supply Lines

Next, you need to disconnect the supply lines that connect the faucet to the water supply. Use an adjustable wrench to loosen the nuts that secure the supply lines to the faucet. Once loose, you can detach the lines by unscrewing them manually.

Step 3: Remove the Faucet Mounting Nuts

Now, locate the mounting nuts that hold the faucet in place. These nuts are usually located underneath the sink. Use a basin wrench to loosen and remove the nuts. Once the nuts are removed, you can lift the old faucet out of the sink.

Installing the New Faucet

Step 4: Prepare the Sink

Before you install the new faucet, it’s important to clean the sink thoroughly and remove any debris or old putty. This will ensure a clean and secure installation.

Step 5: Install the New Faucet

Place the new faucet into the mounting holes on the sink. Make sure it is aligned properly. From underneath the sink, secure the faucet in place by tightening the mounting nuts with a basin wrench.

Step 6: Connect the Supply Lines

Attach the supply lines to the corresponding hot and cold water inlets on the faucet. Use an adjustable wrench to tighten the nuts and ensure a snug fit. Be careful not to overtighten, as it may cause damage to the fittings.

Step 7: Turn on the Water Supply

Once the faucet is securely installed and the supply lines are connected, it’s time to turn on the water supply. Slowly open the shut-off valves under the sink in a counterclockwise direction. Check for any leaks and tighten the connections if necessary.

Congratulations! You have successfully replaced your single handle kitchen faucet. Enjoy the enhanced functionality and aesthetic appeal of your new faucet.
