How to clear the water trap under the washbasin

When water in the washbasin drains away slowly, it may be time to clear the water trap. Follow the step-by-step instructions below or check out our video, which shows you what to do.

What you need:

A bucket and an old toothbrush.


  1. Place a bucket under the water trap.
  2. Unscrew the lower part of the water trap. Save the gasket.
  3. Clean the water trap, e.g. using a toothbrush. Dry off places that you can reach using kitchen roll paper or toilet paper. Throw away residue in the household waste (do not flush it down the toilet).
  4. Put back the gasket and screw on the lower part of the water trap again.
  5. Flush water through the water trap before you take away the bucket to make sure the water trap is sealed properly.

If you are unsure about what you need to do, please contact your caretaker.
