As faucets are used in all residential, commercial, and industrial buildings, it is important to understand what kinds of faucets are available, how they work, and how and where they are used.
Faucets fall into two basic classifications: compression and non-compression. Both types can be further divided into bathroom, kitchen, and utility faucets.
Compression faucets control the flow of water by compressing a seat washer between the valve stem and the valve seat. Non-compression faucets regulate the flow of water by obstructing the water.
Compression faucets for kitchen sink or bathroom lavatories usually combine two compression valves and a mixture that combines the hot and cold water and delivers it through a mixing spout common to both valves.
A plunger located between supply valves controls the drain valve. Some older dwellings may have sinks and lavatories that used individual compression valves and faucets for the hot and cold water.
Non-compression faucets do not rely on the compression of a washer to control the flow of water. Water flow is controlled by rotating balls, rotating cylinders, rotating discs. As these faucets do not use the repeated compression of a washer, they usually require less maintenance than compression faucets.
The most common style of non-compression faucets are washerless, single control, and push button.

Washerless faucets control water flow by matching opening in to two separate discs located in the valve.
Single Control Faucet
These faucets control both the hot and cold water with one hand control.
The rotating cylinder or cartridge faucet controls the water temperature and the rate of water flow by using a balancing piston.
Utility faucets are found in boiler rooms and laundry rooms, and on a building’s outside walls.
They are usually manufactured from extra grade brass, white metallic alloy, or thermoplastic materials.
Most utility faucets are not plated because appearance is generally not important for these.
