Which Tap Cartridge Do I Need?

When it comes to a malfunctioning or leaking tap, it is essential to determine the right type of tap cartridge needed for repair. A tap cartridge is the internal mechanism responsible for controlling the flow and temperature of water in a tap. However, selecting the correct cartridge can be a bit confusing if you are not familiar with the various types available. In this article, we will guide you through the process of identifying the cartridge you need, ensuring a successful repair for your tap.

Types of Tap Cartridges

  1. Compression Cartridge: These are the oldest type of tap cartridges and are commonly found in traditional taps with separate hot and cold handles. Compression cartridges control the flow of water by tightening or loosening the handle, which presses down a rubber washer. Over time, these washers wear out and may cause leaks. If your tap has separate handles and requires multiple turns to turn on the water, you most likely have compression cartridges.

2. Ceramic Disc Cartridge: This type of cartridge is widely used in contemporary taps and is known for its durability and longevity. Ceramic discs inside the cartridge control the water flow and temperature. They require only a quarter or half turn to open or close the water supply. If your tap has a single lever handle that requires little effort to turn on or off, it is likely equipped with ceramic disc cartridges.

  1. Ball Cartridge: Ball cartridges are commonly found in older single-handle taps. They consist of a single lever attached to a rotating ball mechanism with specially designed slots and seals. These cartridges control the water flow and temperature when the lever is moved in different directions. If your tap has a single handle that moves in all directions, you most likely have a ball cartridge.

  2. Cartridge Type Specific to the Brand: Some tap manufacturers design their own cartridge systems unique to their brand. In such cases, it is essential to identify the specific cartridge model needed by referring to the tap's user manual or contacting the manufacturer directly. These cartridges can vary in design and operation, so it is crucial to obtain the correct one to avoid complications during the repair process.

Identifying and Replacing the Cartridge

To identify the tap cartridge you need, follow these steps:

  1. Turn Off the Water Supply: Before attempting any repairs (Seek a professional), always ensure the water supply to the tap is shut off to prevent any accidents or further damage.

  2. Remove the Handle: Use a screwdriver or an Allen key (hex key) to remove the handle. There may be a decorative cap covering the screw that needs to be gently popped off.

  3. Inspect the Cartridge: Once the handle is removed, inspect the cartridge to determine its type. Look for unique features such as washers in a compression cartridge, ceramic discs in a ceramic disc cartridge, or a rotating ball mechanism in a ball cartridge. You may also compare it to images or descriptions of different cartridge types to confirm your findings.

  4. Purchase the Correct Cartridge: Armed with the knowledge of the type of cartridge you need, contact us to purchase the specific cartridge model required for your tap.

  5. Installation: With the new cartridge in hand, carefully follow the manufacturer's instructions for installation. It may involve cleaning the area, replacing O-rings, and lubricating the cartridge before inserting it into the tap.

Remember, if you are unsure about the type of cartridge or feel uncomfortable with the repair process, it is recommended to seek professional assistance from a plumber or contact the tap manufacturer for guidance.


Identifying the correct tap cartridge is crucial when repairing a faulty tap. By understanding the various types of cartridges available and following the steps to determine the type needed, you can ensure a successful repair and a properly functioning tap once again. Remember to take necessary safety precautions and seek professional help if needed. Happy repairing!
