Why does the faucet drip after being used for a long time?

When our household faucet is used for a period of time, there will be a ticking leak. Generally, we can only hear this sound at night, so many times we will feel very scared and troublesome. Then this kind of dripping appears on the faucet. What is the reason for the situation? Let's take a look together.


The valve core of the faucet is damaged and water leaks: caused by the wear of the shaft gasket in the faucet. Use pliers to loosen the gland and remove it, take out the shaft gasket with a clamp, and replace it with a new shaft gasket.

The cause of water leakage in the gap under the faucet bolt: it is caused by the wear of the triangular gasket in the gland. You can loosen the screw to remove the bolt head, then loosen and remove the gland, then take out the triangle seal inside the gland and replace it with a new one.

Water leakage at the joint of the connecting pipe: Generally, the cap nut is loose. At this time, you can re-tighten the cap nut or replace with a new U-shaped gasket.

After the new faucet is closed, dripping will appear. In such a situation, most owners will think that this is a problem with the faucet valve core. In fact, the water dripping for a few seconds after the new faucet is closed is caused by the remaining water in the inner cavity after the faucet is closed. This is a normal phenomenon. But if the water is ticking for a long time, it is a faucet problem, and the water is leaking, indicating that the product has a quality problem.

There are many reasons for faucet leakage, mainly: 1. Poor water quality. Many people do not understand, what is the relationship between poor water quality and a leaking faucet? In fact, poor water quality will cause trash to accumulate in the valve core, which can easily cause the valve core to close tightly. 2. The spool of the faucet is scratched. During use, the valve core is scratched due to the abrasion of foreign hard substances. For example, when the water supply pipe is broken and the water is re-emerged, the water may contain rust or sand particles, which will cause the surface of the valve core to be scratched during the opening and closing process. Sealed and leaking. Therefore, when installing the faucet, be sure to clean up the impurities in the water pipe. 3. Pipeline connection. The water inlet hose and the main body of the faucet leaked at the connection due to improper installation. Most people think that the faucet leakage is a problem with the spool. In fact, as long as the spool is used properly, the spool is not prone to problems. Therefore, if the faucet leaks, it should be analyzed from its essence.

1. The faucet still emits water after the spool is closed. This phenomenon may be caused by the loosening of the pressure cap causing the valve core to become loose and unable to seal the water. The solution is to remove the handle and decorative cover, and re-tighten the pressure cap. Another possibility is that the rubber ring at the bottom of the valve core is deformed. Can not seal the water, the solution is to take out the valve core, check the bottom rubber ring, reset it and reinstall it. 2. Water seeps from around the valve core. This phenomenon may be caused by loosening or displacement of the spool. The solution is to remove the spool and install it again.

We can’t underestimate the faucet problem. The water problem is related to our lives. Therefore, we must pay enough attention to the water problem. Only when our family life is guaranteed can our life be comfortable, and when our life is comfortable, can we have a good life at work. Power, so the faucet problem is not a small problem, but it is not a big problem either.
