Single handle faucets still make up more than 80% of faucet sales and are popular with builders. These faucets are basic and have a single handle that controls temperature and flow. These are available with a side spray which is much less expensive than the pull-out spray faucets. They also allow you to have a spray with a vintage-look faucet.
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.
Some use strong magnets that do a good job to hold the wand in the dock. Others use a smart combination of weights, extremely precise docks and flexible hoses. Whatever the method used in the faucet to keep the spray wand in its place, it might be wise to consult the users′ feedback to see if there are problems with loose fit.
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.
