Sink dripping - what to do?

If it drips in the bathroom around the sink somewhere, that is not only annoying. The constantly dripping water can also cause moisture damage. What can be done against the drops in individual places, read in this article.

Possible drip points

Wash basins can start to drip in very different places. In any case, it is important to pinpoint the location of the event. But this is usually not difficult if you look for drops of water or damp spots.

Drops can:

  • the mixer tap
  • the siphon
  • other parts of the drainage system
  • the drain valve piece in the sink
  • the angle valves

Dripping mixer tap

Dropping the mixer tap is very common. In many cases, this can be remedied by changing the gasket. Gaskets are available for little money in stores, so it's worth the try.

Modern single-lever mixer tapes on the sink have a so-called "Hahnscheibe" installed in their interior, which can also be exchanged in almost all models. Two-lever mixers, on the other hand, have quite classic seals that you can change.

Dripping siphon

A dripping siphon is not a big problem. You can easily replace the sealing rings on the siphon. First of all, check that the threads are in the correct position - very often it is simply due to this. If replacing the seal rings or making sure the threads are not seated will help, you can still try to seal the siphon with hemp. Otherwise you need to replace the siphon - and best of all the drainage system.

Dripping other parts of the drain system

Always make sure that the threads are in the correct position, enough pipe protrusion and intact seals on the dip tube and on the connection piece to the sewer pipe. As with the siphon, you can also make additional seals here, if necessary. Damaged pipes should be the best way to replace the entire system.

Drain valve piece in sink

If the drop comes from the drain valve piece, replace it best or renew the seal (molding ring).

Dripping angle valves

In this case you should consult a specialist. Water pipes are under high pressure and to carry out an exchange of the corner valves as a layman himself is not advisable. Even small mistakes or carelessness can cause a big (and very expensive) water damage. Leave such work to a specialist.

Tips & Tricks

You should always change seals on the two-lever mixer on both sides (hot and cold water). Make sure that the gaskets are very accurate and do not tilt, otherwise you have created a new problem.
