What Causes a Dripping Faucet When Shut Off? Expert Tips for Repair

Leaking faucets are a common problem. While it may seem like there is only a small amount of dripping, over time it can lead to significant water waste and may damage the sink. Let's take a look at why a faucet continues to drip even when it’s turned off.

一.Why does a faucet keep dripping when it’s turned off?

1. Turn off the water supply, then use a tool to remove the logo on top of the faucet and unscrew the screw inside.

2. Remove the handle and turn the valve core in the direction of opening the faucet until it is taken out, and set it aside.

3. Remove the screws that hold the sealing ring in place, then purchase a new sealing ring to replace it.

4. Reassemble the faucet components and test it. If the faucet still leaks when turned off, you’ll need to buy a new faucet. If it doesn’t leak when turned off, it indicates that the installation is successful.

二.How to buy a quality faucet

1.Check the valve core

The valve core is like the heart of the faucet and is a crucial component. The quality of the valve core significantly affects the lifespan of the faucet. When choosing a faucet, select one with a high-quality valve core to ensure a longer lifespan.

2.Examine the craftsmanship

The manufacturing process of a faucet is also essential. A well-manufactured faucet will have a smooth and shiny zinc-plated layer, and there should be no color differences or defects, such as black spots or areas with missing plating. When purchasing, carefully check the surface of the faucet to ensure it is smooth and defect-free before buying.

3.Check for excessive metals

Since many faucets are used to control drinking water, excessive heavy metals are unacceptable, as they could affect the health of the user. To ensure safety, ask the seller for product quality certificates and the faucet's testing report upon purchase.

In conclusion, we have discussed the reasons why a faucet keeps dripping when turned off and how to buy a quality faucet. We hope this information is helpful to you. Faucet leaks are primarily due to worn-out internal sealing rings, which can be cumbersome to replace, and it is generally recommended to replace the entire faucet.
