Why is the faucet dripping?<\/h2>\n

There are several reasons why a faucet may continue to drip. These are the most common:<\/p>\n

1. Worn seal (rubber ring)<\/h3>\n

In most cases, the problem lies with the internal seal. With constant use, it wears out and loses its ability to keep the water completely sealed.<\/p>\n

2. Damaged cartridge (single-lever faucets)<\/h3>\n

More modern faucets use ceramic cartridges. If the cartridge is worn or cracked, it will start to leak water.<\/p>\n

3. Clogged aerator<\/h3>\n

The faucet spout, called an aerator, can accumulate limescale and debris, causing irregular pressure and constant dripping.<\/p>\n

4. Loose internal parts<\/h3>\n

Over time, screws and internal components can loosen, making it difficult to completely shut off the water.<\/p>\n

5. Water pressure too high<\/h3>\n

Even a new faucet can drip if the water pressure in the system is excessive. This requires a solution in the valve or piping.<\/p>\n

What to do when the faucet won't stop dripping<\/h2>\n

Here's what you can try before calling a professional. In some cases, the solution is simple.<\/p>\n

1. Check and clean the aerator<\/h3>\n

Unscrew the faucet nozzle, remove the aerator, and wash it. If there is a lot of limescale, soak it in vinegar. This often solves minor dripping problems.<\/p>\n

2. Tighten the internal mechanism<\/h3>\n

Use a suitable wrench to remove the tap cover and check for loose screws. A simple tightening may stop the leak.<\/p>\n

3. Replace the seal or cartridge<\/h3>\n

If the faucet is old, the seal may be worn out. In single-lever faucets, the cartridge is usually responsible. Both can be replaced, but require tools and some care.<\/p>\n

4. Check the water pressure<\/h3>\n

If you notice vibration, noise, or excessive pressure, there may be a problem with the pressure reducer. In such cases, it is best to call a professional.<\/p>\n
