A dripping tap may seem like a minor problem, but in addition to the constant annoyance, it also wastes water and increases your monthly bill. In fact, a simple dripping tap can waste dozens of liters per day. The sooner you fix the problem, the better for your pocket and your home.
In this guide, we explain the main causes, what you can do on your own, when to call a professional, and why the Canalizador de Lisboa It is the safest and most efficient solution for repairing any type of faucet.
Why is the faucet dripping?
There are several reasons why a faucet may continue to drip. These are the most common:
1. Worn seal (rubber ring)
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.
2. Damaged cartridge (single-lever faucets)
More modern faucets use ceramic cartridges. If the cartridge is worn or cracked, it will start to leak water.
3. Clogged aerator
The faucet spout, called an aerator, can accumulate limescale and debris, causing irregular pressure and constant dripping.
4. Loose internal parts
Over time, screws and internal components can loosen, making it difficult to completely shut off the water.
5. Water pressure too high
Even a new faucet can drip if the water pressure in the system is excessive. This requires a solution in the valve or piping.
What to do when the faucet won't stop dripping
Here's what you can try before calling a professional. In some cases, the solution is simple.
1. Check and clean the aerator
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.
2. Tighten the internal mechanism
Use a suitable wrench to remove the tap cover and check for loose screws. A simple tightening may stop the leak.
3. Replace the seal or cartridge
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.
4. Check the water pressure
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.
When should you call a plumber?
Some signs indicate that it is no longer worthwhile to insist on homemade solutions:
- You've already replaced the seal, and the tap is still dripping.
- You can't dismantle the tap without damaging it.
- The cartridge is specific and difficult to replace.
- The faucet is dripping more and more.
- There are signs of moisture or leakage in the lower cabinet.
- The water pressure seems irregular.
In these cases, professional intervention prevents further damage and ensures that the problem does not return.
How much does it cost to fix a dripping faucet?
Prices depend on the type of tap, the severity of the problem, and the parts required. In Lisbon, repairs usually range from €60 and €150, especially if you need to replace the cartridge or internal components.
