Why does the bathroom faucet drip when it is turned off?

First, it depends on the structure of the sanitary faucet. If the bathroom faucet is an old-fashioned rubber pad, which is tightened by rotating the bathroom faucet handle, you can unscrew the bathroom faucet shell with a big wrench and replace the rubber pad about the size of cents. If there is no rubber pad, you can buy another bathroom faucet. At present, plastic faucets are more common, but 3-4 yuan / piece. If it is a new type of magnetic valve sanitary faucet, it has to change the sanitary faucet because it is difficult to find the magnetic valve block on the market. This kind of sanitary faucet is only a little more than 10 yuan. The above two refer to a single sanitary faucet. If it is the bathroom faucet of the basin, about tens of yuan or hundreds of yuan, you can buy the valve core at the place where the bathroom faucet is sold. The price difference of the valve core is very large, about 10-40 yuan.

The disassembly procedure of this sanitary faucet is:

I. pry the small red and blue dot under your hand, and you can see the hole.

II. Use a flashlight to check a small screw fixing the handle inside. If it is a cross or a slotted mouth, put it in with a corresponding small screwdriver and loosen it, you can remove the handle.

III. after the handle is removed, you can see a large copper nut fixing and pressing the valve core, and unscrew and remove it with a large wrench.

IV. at this time, the whole valve core can be removed and replaced with a new valve core.

5、 But note that the specifications of the valve core are the same. When installing a new one, it should be noted that the valve core has two protruding points, which are used for positioning, and should fall into the small hole under the base of the sanitary faucet accordingly. Finally, install according to the disassembly procedure and vice versa.
