Dissembling the faucet handle is the most difficult part in dissembling the faucet parts; over time, corrosion virtually welds the handle to the stem. Locate the screw on the faucet handle. It may be exposed, or you may need to pry the center off the faucet handle. Using a special handle puller makes the work easier.
