Step 4 · Remove Faucet Handle
Locate the small decorative cap on the faucet handle, often marked with a red/blue hot/cold symbol. Carefully use the tip of a flathead screwdriver or a utility knife to pry this cap off. Underneath, you will find a small set screw. Select the correct size Allen wrench from your set and insert it into the screw. Turn the Allen wrench counter-clockwise to loosen the screw. You only need to loosen it a few turns; you do not need to remove it completely. Once loose, lift the entire handle straight up and off the faucet body.
