DYI-FYI #57 teaches you how to fix a leaky faucet in this video. First, have to distinguish if the water drips from the tap or from the handle. If the water is leaking form the tap you need a new washer; if it drips from the handle you need a new o-ring. First, turn the water off using the valves under the sink. Next, drain the faucet by turning it on of course and grab a towel to place in the sink to prevent scratching while you work! Next, you'll have to remove the decorative topping to reveal the screw underneath the handle. Turn this stem counter-clockwise. Take out the stem and replace either the washer or o-ring depending on your type of leak. To finish up, put the parts back in the way you took them out. Now, you've got a perfect faucet!
