Faucet Valve Types
Ball faucets are composed of a single handle which can be adjusted to either side for control of water temperature and pressure. This flexibility comes from a rounded ball cap sitting atop the faucet spout.
Inside the faucet body is a plastic or metal ball, O-rings, chambers and slots. Ball faucets are known for being the most leak-heavy of the other washer-less faucets due to the O-rings and rubber seals drying out or when the springs weaken.
Best Use: Bathrooms and kitchens, especially if they are in restaurants or public establishments that see large volumes of people. They are easy to use and only require the turning of one handle instead of two.
Disc faucets have a single lever over a wide, cylindrical body that combines hot and cold water in a pressure balance cartridge. This cartridge has two ceramic disks on the base that are used for controlling the water volume, while the temperature is controlled by swaying the handle from side-to-side. These faucets use the newer faucet technology and seldom require repairs.
Best Use: Faucets like these are best for use in bathrooms, kitchens and laboratories. They can also be installed in warehouses or facilities that rely on water applications as these faucets are sophisticated and require infrequent repairs.
A long-standing faucet type, the compression washer faucet has been in use since the beginning of indoor plumbing. Utility sinks often use the newer versions of these faucets. They have two handles for hot and cold water and a compression stem, which is a kind of screw that allows water to flow out. When the washer is compressed, the water is shut off.
Best Use: These faucets are best used in residences and offices as these are the most standard.
The spout and nozzle are the anatomical “neck” of the faucet. This tube-like structure transports water out of the faucet and into the sink basin or drain, depending on the setup. Spouts are often movable, in which cases they are called swivel or swing spouts. They can also be non-movable or fixed. Spouts are not invariable; they come in a variety of styles. Some of these style and shape options are even available in the three main sink categories.
|Standard Swing||Composed of a long straight body|
|Gooseneck||Higher neck composed of a curved “U”-shaped body|
|Double-Jointed||Possesses two tubes connected together, a straight, long one like in the standard swing, on which a shorter curved one is connected to|
|Wok Filler||Long and straight, like the standard swing but much thinner and with a more angular spout|

While the latter is subjective, the former depends on basic plumbing knowledge and the practice of working with faucets. In addition, considering the position (mount) and colors of the faucet will help you select the right one.
