First, make sure to do the necessary preparation work, including purchasing a valve core of the same model for replacement. Therefore, when buying, be sure to check the product model to avoid installation issues. It is advisable to choose a valve core from the same brand as your faucet, as this makes it easier to find a matching model. Additionally, gather the necessary tools such as a screwdriver, wrench, and a small knife.

2. Remove the Hot and Cold Water Button

Before replacing, you should first turn off the water supply to the faucet to prevent any water flow during the replacement. Next, locate the button on the top of the faucet and use a small knife to pry it off. This will expose the internal screws.

4. Remove the Valve Core

Once the handle is removed, you will see the valve core. Some valve cores may have an outer cover that needs to be taken off first. At this point, you can see the valve core clip, which can be clamped with needle-nose pliers, and then turned clockwise to unscrew it.

5. Installation

After removing the old valve core, you can start to install the new one. The installation process is not complicated; simply reverse the disassembly steps. First, install the components, then the new valve core, followed by the handle and the button. Once everything is installed, test the faucet to check if the handle is tightened properly and if there are any leaks.
