Faucet leaking from the top: causes and solutions to know

Do you have a water leak at your mixer tap? This common problem can cause inconvenience and significantly increase water consumption, especially if the leak is not quickly fixed. In this article, we will explain the possible causes of this leak at the top of the tap as well as the different solutions to repair it.

Signs of a tap leaking from the top

First of all, it is essential to precisely identify the source of the problem in order to determine the best solution. Here are some common indicators of this type of leak:

  • Water drops constantly escaping from the top of the tap, near the handle;
  • An unusual noise when using hot or cold water;
  • A decrease in water pressure may also be noticed.

Possible causes of the leak

Natural wear of the cartridge

The first possible cause: wear of the cartridge. The cartridge is a part located inside the mixer tap, used to blend hot and cold water and thus adjust the temperature according to the user's needs and wishes. Over time, this part can wear out and lose its tightness, causing water leaks at the top of the tap.

The spout seal in poor condition

Another possible cause concerns the seal located at the end of the spout. Like the cartridge, this rubber seal can deteriorate over time, causing a loss of tightness between the spout and the body of the tap. This can also cause leaks from the top.

A water pressure problem

Another potential cause is an abnormal variation in water pressure in the pipes. Too high a pressure can put strain on the cartridge and seals, reducing their effectiveness and lifespan.

How to repair a tap leaking from the top?

To solve your leak problem, it is crucial to precisely identify the cause in order to choose the best solution. Here are some methods to fix problems related to the different causes mentioned above:

For a worn cartridge

  1. First, shut off the water supply to your tap and disconnect your drain;
  2. Then dismantle the mixer to access the cartridge using a screwdriver or an adjustable wrench;
  3. Once you have access to the cartridge, examine it and check if it is indeed in poor condition. If so, it will need to be replaced with a new one (you can check the model reference written on the old cartridge);
  4. Run your tap after reassembling all parts to check if the leak has been fixed.

For a faulty seal

  1. First, cut off the water supply to your installation;
  2. Then only dismantle the spout part of the mixer by unscrewing the spout body with an adjustable wrench;
  3. Check the condition of the seal: if it is cracked, flattened, or broken, replace it with a new one;
  4. Turn the tap back on to see if the leak has stopped.

For a water pressure problem

If it turns out that the pressure in the pipes is too high, it may be useful to install a pressure reducer just before the water supply to your tap. This device will regulate the pressure, thus avoiding excessive strain on the tap parts and their premature wear.

Preventing leaks from the top of the tap

To prevent your tap from suffering repeated leaks, a few tips can be put in place:

  • Regularly check the condition of the seals to replace them at the first signs of wear;
  • Be careful not to handle the mixer roughly to limit this wear;
  • Consider arranging regular upkeep of your tap, especially by removing lime scale deposits that can build up at the spout or cartridge.

By following these tips and staying alert to early signs of a possible leak, you should avoid many troubles and extend the lifespan of your mixer tap. Do not hesitate to call a craftsman if needed, especially if you are not familiar with plumbing or if the problem persists despite your repair attempts.
