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

When our household faucet is used for a period of time, it will leak. Normally, we can only hear this sound at night, so many times we feel very scared and troublesome. Then this dripping water appears on the faucet. What is the reason for this situation? Let's take a look together.
Damage and leakage of the valve core of the faucet: caused by wear on the faucet shaft gasket. Use pliers to loosen the gland and remove it. Use a clamp to remove the shaft washer and replace it with a new one.
The reason for water leakage in the gap under the faucet bolt is due to the wear of the triangular washer in the gland. You can loosen the screws to remove the bolt heads, then loosen and remove the gland, and then remove the triangular seal inside the gland and replace it with a new one.
Leakage at the connection pipe joint: Generally, the nut is loose. At this point, you can retighten the cap nut or replace it with a new U-washer.
After the new faucet is turned off, there will be dripping water. In this case, most homeowners will consider this to be a problem with the faucet valve core. In fact, the dripping of water a few seconds after the new faucet is turned off is caused by the residual water in the inner chamber after the faucet is turned off. This is a normal phenomenon. But if the water keeps ticking for a long time, it's a faucet problem, and the water is leaking, indicating a quality issue with the product.
There are many reasons for faucet leakage, mainly including: 1. Poor water quality. Many people don't understand the relationship between poor water quality and leaking faucets? In fact, poor water quality can cause garbage to accumulate in the valve core, which can easily cause the valve core to close tightly. 2. The faucet valve core is scratched. During use, the valve core was scratched due to wear and tear from foreign objects. For example, when the water supply pipe ruptures and the water comes out again, the water may contain rust or sand particles, which can cause scratches on the surface of the valve core during the opening and closing process. Sealing and leakage. Therefore, when installing the faucet, it is necessary to clean the impurities in the water pipe. 3. Pipeline connection. Due to improper installation, the inlet hose and faucet body leaked at the connection. Most people believe that the leakage of the faucet is a problem with the valve core. In fact, as long as the spool valve is used properly, it is not easy to have problems with the spool valve. Therefore, if the faucet leaks, it should be analyzed fundamentally.
After the valve core is closed, the faucet will still discharge water. This phenomenon may be caused by the loose 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 then retighten the pressure cover. Another possibility is that the rubber ring at the bottom of the valve core is deformed. Unable to seal water, the solution is to remove the valve core, check the bottom rubber ring, reset and reinstall. Water seeps out from around the valve core. This phenomenon may be caused by loose or displaced spool valves. The solution is to remove the spool valve and reinstall it.
