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.
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.
Important: After making repairs to a disc faucet, it is imperative the handle in the ON position, then open the shutoff valves slowly. The ceramic discs can be cracked by the sudden release of air from the faucet. Once the water is running steadily, it is safe to close the faucet.
