Can a Faucet Cartridge be Repaired? A Comprehensive Guide by Fengcai

Faucet cartridges are known to be the heart of any plumbing fixture. They control the flow of water and help in regulating the temperature in the faucet. However, with prolonged usage, they tend to wear out and may eventually start to leak or drip.

In this article, we'll guide you on whether you can repair your faucet cartridge or replace it.

Firstly, let's understand what a faucet cartridge is and how it works. A faucet cartridge is a component that controls the flow and temperature of water in a single-handle faucet. Two types of faucet cartridges are commonly used - ceramic and cartridge cartridges. Ceramic cartridges are found in single-handle faucets that move up, down, or sideways to adjust the water flow and temperature.

On the contrary, cartridge cartridges use a rubber O-ring to control the flow and temperature of water. When they wear out, the faucet may start to leak or drip, leading to water wastage and increased water bills. Now that you know what a faucet cartridge is let's move on to whether it can be repaired or not.

In some cases, you can repair the faucet cartridge without replacing it completely. You may want to try repairing the cartridge if it's only leaking or dripping slightly. However, if the faucet cartridge has been damaged beyond repair or has worn out over a prolonged period, it may be time to replace it. Here are some steps to repair and replace the faucet cartridge.

Repairing the Faucet Cartridge

Before you start repairing the faucet cartridge, it's essential to turn off the water supply to the faucet. You can do this by shutting off the water valve under the sink. Once you've turned off the water supply, follow these steps:

1. Remove the faucet handle

Use a screwdriver to remove the faucet handle, which should reveal the cartridge. You can also check the manufacturer's manual to understand how to remove the faucet handle.

2. Check the faucet cartridge

Once you've removed the handle, check the cartridge for any visible damages. If it's just a tiny crack or a worn-out O-ring, you may want to replace it. However, if the cartridge is beyond repair, then you need to replace it.

3. Replace the O-ring

If the O-ring is worn out, you can replace it by gently pulling it out of the cartridge and replacing it with a new one. Ensure that the new O-ring is the correct size and fits snugly in the cartridge. This should fix the leaking or dripping faucet.

Replacing the Faucet Cartridge

If the faucet cartridge is beyond repair or has been damaged, then you need to replace it. Here are some steps to follow when replacing the faucet cartridge:

1. Turn off the Water Supply

Before starting any plumbing work, always turn off the water supply to avoid any unnecessary leaks or water damages.

2. Remove the Faucet Handle

Using a screwdriver, remove the faucet handle to reveal the cartridge underneath.

3. Remove the Old Faucet Cartridge
