Cartridge Faucet - this washerless faucet is identified by the narrow metal or plastic cartridge inside the faucet body; and it is available in both single and double handled cartridge designs. Cartridge faucets have a hollow cartridge insert that lifts and rotates to control the flow and temperature of water. Dripping at the spout occurs when the cartridge seals wear out. Leaks at the base are caused by worn o-rings.
The faucets with detachable spray wands have become extremely popular during the last decades. But there is always some doubt whether the pull-out wand will have a snug enough fit into its dock. If the wand does not sit very well, the faucet loses a lot. It can be beautifully designed, but if the spray head does not sit where it should, the whole faucet will look cheap and inferior. That is why the leading manufacturers of kitchen faucets have done their best to secure the wand firmly in its place.
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.
Faucets begin to drip when washers, o-rings, or seals inside the faucet are dirty with sediment, covered with mineral deposits, or just worn-out. Fixing a faucet is fairly easy, but varies depending on the type of faucet you have (see below for specific description and instructions). Once you know your faucet design, you can properly disassemble the faucet, locate the source of the leak, and then replace the worn parts or clean dirty parts.
