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.
Once you have the faucet out, replace all rubber washers and o-rings. When replacing washers, check the condition of the metal valve seats inside the faucet body. If the valve seats feel rough, they should be replaced or resurfaced.
Compression Style Faucets - this design is used for many double-handle faucets and is the old-fashioned style faucet (when shutting the faucet off, you usually can feel the rubber washer being squeezed inside the faucet.) Compression faucets have separate controls for hot and cold water and can be identified by the threaded stem assemblies inside the faucet body. Compression faucets all have washers or seals which control water flow and need to be replaced regularly over time. The replacement parts are inexpensive and easy to replace.
If you have never held a wrench in your hand, you probably do need a plumber to help you with the installation. But if you know how to connect an end of a pipe to the supply, you can do all the things on your own. Every faucet that is worth your attention will come with detailed instructions. But the process is highly intuitive, too. Basically, the lower part of the faucet comes through the installation hole on your sink or counter-top, hot and cold water pipes connected and the faucet fastened with nuts from beneath.
