Types of sink faucets
There are four main types of faucet – each type works and breaks differently and requires different tools for repair.
Compression cranes are the oldest of the four types. All compression cranes have separate turnable knobs for hot and cold water. You tighten and untighten these knobs by hand, turning them to allow water to flow out of the faucet. Compression faucet handles are connected to two stem assemblies. The stem assemblies are essentially bolts with washers at the end. These nodes are located above the valve seat of the faucet, where water flows into the valve. When you close the valve, you move the stem assembly down to the valve seat. When it reaches the valve seat, the stem washer shrinks over the valve seat and shuts off the flow of water. When you open the faucet again, the washer rises and allows the water to flow again.
Ball faucets were designed to be the first valve without a washer. Unlike compressor taps, the ball faucet has only one handle for hot and cold water. They are especially common in kitchen sinks. If the handle of your crane can freely rotate up and down and form from side to side, then this is probably a ball faucet. Temperature, pressure and water flow depend on where you position the ball valve handle.
Disk faucets have much more modern design, than compression or ball faucets. Like ball faucets, they were designed not to rely on washers. Disc mixers are also significantly more durable than compression or ball mixers. The body of the disk crane is much wider than other types of faucets, and they are usually cylindrical. The handle of the disk faucet moves up and down and side to side, like ball faucets, but they usually do not have so much free movement.
Unlike other types of faucets in this list, cartridge mixers can have one or two handles. However, unlike compressor faucet, you do not need to turn the knobs to control the flow of water. Instead, you can simply rotate the tap handle to supply water. If something is wrong, the handle should turn from “off” to “on” in one smooth and easy movement. Single-handle cartridge faucet move up and down to control water flow and side to side to control temperature, like disk faucets.
