How to Change a Ceramic Disk Cartridge from a Wall-Mount Kitchen Faucet

Wall-mount kitchen faucets are an elegant addition to the home. These kitchen faucets are designed to mount directly to the backsplash behind a kitchen sink, and pair well with vessel sinks as well as farmhouse-style sinks. Available in designs ranging from ornate and decorative to sleek and minimalistic in style, there is a wall-mount faucet to match any kitchen.

While the style and design of these faucets might vary greatly, these faucets share a similar functional component — a ceramic disk cartridge. This cartridge is what makes it possible for homeowners to quickly turn on and off the flow of water.

In this guide, learn how to change out a damaged or worn-out ceramic cartridge for a wall-mount faucet.

What Is a Ceramic Disk Cartridge?

Located behind the handle of a wall-mount kitchen faucet is the ceramic disk cartridge. This cartridge acts as the temperature and water-flow control of the faucet. There is a cartridge resting behind both the hot and cold handle of a dual-handled, wall-mount faucet.

Inside these cartridges are discs designed with ceramic carbide. These rotate to control the flow of water and are designed with extreme durability in mind.

However, over time, the cartridge can wear, which necessitates replacement. The good news is that replacing a ceramic disk cartridge is relatively easy, and most homeowners will opt to replace the cartridge on their own.

Signs It Is Time to Replace a Faucet Cartridge

When a faucet handle is leaking, even when the handle is in the "off" position, it may be due to the deterioration of the cartridge. Additionally, if the faucet handle is difficult to move, the cartridge may be at fault. By following the steps below, homeowners can quickly replace this piece, restoring their faucet.
