Second - Disassemble the Faucet: The same basic principals apply to all faucet types when starting to take a faucet apart for repair or replacement. Keep all parts and layout in the order you take them apart. This will help you both put the faucet back together and identify the parts to be replaced. See below for specific variations in faucet dis-assembly.
To disassemble unscrew the setscrew and pull off handle. Tighten the plastic adjusting ring inside the cap by turning it with a special flat adjusting tool-or fit tow screwdrivers into the slots and cross their blades to turn the ring. If your ball-style faucet with this type of cap is leaking from the spout, first try tightening the cap with channel pliers. Still leaking? Disassemble and replace worn/broken parts. Often you need to lift out the ball and replace the rubber seats and springs on both sides of the valve. If the faucet leaks around the spout, replace worn o-rings. Replace rotating ball only if clearly worn.
Disc Faucet - a top-quality fixture, the disc faucet has a single handle and is identified by the wide cylinder by the faucet body. The cylinder contains a pair of closely fitting ceramic discs that regulate the water flow: a movable upper disc turns or lifts and lowers against a fixed lower ceramic disc. Most ceramic disc faucets don′t drip or leak because they′re made to be almost maintenance free. Dripping at the spout occurs when the neoprene seals or cylinder openings are dirty. If the faucet continues to leak after cleaning, then install a new cylinder.
For pull-down models, the hose needs to be guided through the faucet body and spout, for touch sensitive models, there will be a battery pack that needs to be connected to the contacts.
