First - Determine Faucet Design: There are four basic faucet designs: ball-style, cartridge, disc, and compression. Sometimes a faucet type can be determined by the outer appearance, but often the faucet must be taken apart to identify what kind of faucet it is. The four faucet designs come under two categories: washer and washer-less.
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.
Ball-style Faucet - this washerless faucet has a single handle and is identified by the hollow metal or plastic ball inside the faucet body which controls water temperature and flow. Many have a rounded cap with knurled edges located under the faucet handle. Dripping at the faucet spout is caused by worn valve seats, springs, or a damaged ball. Leaks around the base of the faucet are caused by worn o-rings.
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.
