To disassemble unscrew the setscrew and pull off handle. Though these faucets are washerless, they do have inlet and outlet seals that may leak, or sediment may build up inside the inlets and cause leaks. After removing the escutcheon cap, lift out the cylinder and clean the neoprene seals and cylinder openings. Be sure the faucet is in the "open" position when replacing seals.
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.
Faucet manufacturers make several types of replacement kits for ball-type faucets; some kits have only the springs and neoprene valve seats, while better kits also have the cam and cam washer.
A small drip from a leaky faucet might seem like a little annoyance, yet it actually can cost you hundreds of dollars a year in water down the drain and next to nothing to fix. A leaky faucet is one of the most common home plumbing problems. Faucets are relatively easy to fix-once you know how they work and what to do to fix them.
