Anatomy of a Faucet

Carly Reynolds

There are two basic constructions for faucets. There are many different types, but all use one of the following four parts to make them work: cartridge, compression, ball or disc.


Faucet Cartridge

High-quality faucets feature cartridges, which require no washers and no springs to make them function. Faucets with cartridges have a much less chance of leaking. The cartridge itself is very durable and often comes with a warranty.

Compression Faucets

These faucets feature seals that close against valves to monitor water flow. To prevent leaking, these faucets feature O-rings and seals.

Disc Faucets

The disc faucet has a mobile upper disc and a stationary lower disk. The combination of these discs regulates the flow of water.

Ball Faucets

This type of faucet is washerless and operated by a lever and slotted ball. If your ball faucet is leaking, it is normally due to worn inlet seals or O-rings.

Faucet Aerator

This device reduces the quantity of water that flows from your faucet. It also ensures adequate water flow.
