One of the first things to know before shopping for a faucet is your hole configuration. Most sinks come with holes drilled to receive the faucet and sometimes accessories such as a sprayer, soap dispenser, hot beverage or filtered water faucet. One hole sinks are for single-control faucets, three hole are for single-control faucets with a sprayer and/or accessories and four holes are for single-control or two-handle sinks with various accessories. If you have an under-mount or apron front sink the holes are drilled into the countertop behind the sink.
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.
