    3. Remove the Faucet Handle

    To remove the faucet handle, you will need to:

    1. Turn off the water supply to the faucet.
    2. Remove the screws that hold the handle in place.
    3. Pry the handle off of the faucet body.

    Turn off the water supply to the faucet.

    The first step is to turn off the water supply to the faucet. This will prevent any water from spilling out when you remove the handle. To do this, find the shut-off valve for the faucet and turn it clockwise until it is completely closed.

    Remove the screws that hold the handle in place.

    The next step is to remove the screws that hold the handle in place. These screws are usually located on the back of the handle. Use a screwdriver to remove the screws.

    Pry the handle off of the faucet body.

    Once the screws are removed, you can pry the handle off of the faucet body. To do this, use a flathead screwdriver or a pry bar. Gently pry the handle up and off of the faucet body.

    Be careful not to damage the faucet body.

    When prying the handle off of the faucet body, be careful not to damage the faucet body. If you are using a pry bar, be sure to use a soft cloth or towel to protect the faucet body.

    4. Repair or Replace the O-Ring

    Once you have removed the faucet handle, you can inspect the O-ring. The O-ring is a small rubber ring that seals the faucet handle to the faucet body. If the O-ring is damaged or worn out, it will allow water to leak out of the faucet.

    To repair or replace the O-ring, you will need to:

    1. Remove the old O-ring.
    2. Clean the faucet seat.
    3. Apply a thin layer of plumber’s grease to the O-ring.
    4. Insert the new O-ring into the faucet seat.

    Remove the old O-ring.

    The first step is to remove the old O-ring. To do this, use a small flathead screwdriver or a pick to pry the O-ring out of the faucet seat.

    Clean the faucet seat.

    Once the old O-ring is removed, you will need to clean the faucet seat. To do this, use a clean cloth or paper towel to wipe away any dirt or debris.

    Apply a thin layer of plumber’s grease to the O-ring.

    Next, apply a thin layer of plumber’s grease to the O-ring. This will help to create a seal between the O-ring and the faucet seat.

    Insert the new O-ring into the faucet seat.

    Finally, insert the new O-ring into the faucet seat. Be sure to seat the O-ring properly so that it creates a seal.

    Test the faucet.

    Once you have installed the new O-ring, turn on the water supply to the faucet and test it. The faucet should no longer leak.
