1. Identifying the Cartridge

What is a faucet cartridge?

A faucet cartridge is a small, cylindrical valve that controls the flow of water through a faucet. It is located in the body of the faucet, behind the handle. Faucet cartridges come in a variety of sizes and types, but they all perform the same basic function.

How to identify the cartridge type

The first step to cleaning a faucet cartridge is to identify the type of cartridge you have. There are two main types of faucet cartridges: compression cartridges and ceramic disc cartridges.

• Compression cartridges are the most common type of faucet cartridge. They are made of a rubber or plastic washer that is compressed to create a seal and stop the flow of water.
• Ceramic disc cartridges are a newer type of faucet cartridge that are more durable and longer-lasting than compression cartridges. They are made of two ceramic discs that rub against each other to create a seal and stop the flow of water.

To identify the type of cartridge you have, look for the following markings on the cartridge:

• Compression cartridges will have a rubber or plastic washer.
• Ceramic disc cartridges will have two ceramic discs.

If you cannot find any markings on the cartridge, you can try to remove the cartridge and look at it more closely. Compression cartridges are usually made of a single piece of material, while ceramic disc cartridges are made of two separate pieces.
