To disassemble unscrew the bonnet from the faucet, using slip-joint pliers. Remove the valve stem, keeping in mind this has reverse threads, so unscrew it by turning it clockwise. Older compression faucets may have corroded handles that can be difficult to remove. Most hardware stores and rental centers have a specialty tool called a Handle Puller which makes the job easier.
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.
But there are faucets on which the spots will be much less visible and easier to clean. You only have to find a faucet with a surface designed especially for the clean look. If you do an online research, you can find references to such a feature in the descriptions that are available on the manufacturers′ or retailers′ sites. If you find a site that does not offer you a detailed description, it is a good reason for you to leave that site. There are a lot of customer oriented sites on the Internet that supply even more information about the items they feature than you can possibly get at your offline store.
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.
