For faucets, whether disassembling or installing, attention needs to be paid to various aspects. What size is the hex screw for the faucet handle? What should one be aware of when installing a faucet?

The size of the hex screw for the faucet handle

Typically, the size is around 36 millimeters, and a 14-inch adjustable wrench can be used for disassembly or installation. However, since there are many different types of hex screws on the market, and each may vary, the specific size should be determined based on actual use. Additionally, whether disassembling or installing a faucet, it is important to first turn off the main water supply valve to prevent continuous water flow.

Installation precautions for faucets

1. For those with no experience in faucet installation, it is not recommended to attempt the installation themselves; it is better to hire a professional. This is especially true for high-end products, as their installation requirements are often more stringent and must be followed step by step according to the installation instructions. Otherwise, issues such as water leaks may occur after installation.

2. Before installing the faucet, protective measures should be taken to avoid damage to the faucet from hard objects. Additionally, care should be taken to prevent contamination from materials such as cement or glue, as this can easily damage the surface coating.

3. When installing a faucet in a newly built house, the water supply pipes are newly laid and likely to carry some impurities. Therefore, it is essential to clean them thoroughly before installation to ensure the faucet operates correctly after being installed.

4. After completing the installation of the faucet, it is necessary to test it to ensure it functions properly. During use, care should be taken to avoid excessive force, as this could damage the faucet; simply turning it gently is sufficient. Also, the surface should be cleaned to prevent any residue from affecting its shine.
