Step 5 · Replace Spout O-Rings
Since the leak was identified at the base of the spout, the O-rings must be replaced. Lift and twist the entire spout to remove it from the faucet body. You will see two or more rubber O-rings around the base. Use a small pick or flathead screwdriver to carefully remove the old O-rings without scratching the metal grooves. Clean the grooves with a rag. Lightly coat the new O-rings from the repair kit with plumber's grease and slide them into place. Re-install the spout onto the faucet body.
