One. How to remove the faucet.
1. First, close the water inlet valve. The water inlet valve is typically located under the kitchen countertop.
2. Adjust the size of the wrench to fit the faucet head. Use the wrench to tighten the faucet head.

3. Separate the inlet pipe and hose. First, use a wrench to disconnect the inlet pipe and hose. When disassembling, be particularly careful. Hold the pipe with your left hand and rotate the wrench with your right hand to easily disconnect the two.
4、Remove the fasteners securing the faucet to the sink, allowing the faucet to be detached from the sink.
5. Use a saw to cut through the joint and remove the basin from the countertop.
6. After removing the sink, use a saw to cut through the rusted portion that was difficult to remove, and the faucet has been successfully disassembled.
Two. What to do if a faucet is too tightly tightened and cannot be removed?
The primary reason old faucets won't turn is due to rusted screws. Avoid using excessive force to turn them, as the screws are prone to breaking, leading to water leakage. The solution is to use a wrench to loosen the faucet cap slightly, then repeatedly turn the faucet on and off. once water starts to come out from the cap, the faucet can be easily removed.
Close the main water valve. It is essential to turn off the water supply valve before removing any faucets. Otherwise, after removing the clean water faucet, the house will flood. Try turning both left and right. The first turn after rust formation is usually the most difficult, no matter which direction you turn. once you turn it, the remaining rust layer will become relatively easier to turn.
Apply a few drops of kerosene to the threads, wait a few minutes, then tighten. Kerosene can provide some lubrication, making it easier to turn. Alternatively, you can use machine oil or vinegar. Apply to the threads and wait for it to penetrate before attempting to turn. Boil water and pour it over the external threads of the faucet. This can help with tightening due to the principle of thermal expansion and contraction, but the effect is not as effective as using a lubricant.
