How to clean and clear the floor drain


Clear the floor drain at least twice a year, so that it will function optimally. If you notice that it is beginning to smell bad, or if the water is draining away slowly, don’t wait, clean the floor drain immediately.

What you need:

Washing-up brush and washing-up liquid.

Floor drain with insert – step-by-step:

  1. Remove the drain cover, e.g. using a small screwdriver.
  2. Lift out the water trap.
  3. Disassemble and clean the water trap, inside and outside. Throw away residue in the household waste (do not flush it down the toilet).
  4. Reassemble the water trap and put it back. Ensure the sealing ring is in place and is pressed in properly to avoid a bad smell from the drain.
  5. Flush for a short while, so that the water trap fills up with water.
  6. Clean the drain cover and put it back.

Floor drain (cast iron) – step-by-step:

  1. Remove the drain cover.
  2. Clear the drain and clean inside. Throw away residue in the household waste (do not flush it down the toilet).
  3. Flush through with a strong jet of water.
  4. Clean the drain cover and put it back.

Is there a bad smell when you have not used the shower for a while?

If you have been away, the water trap may have dried out. This applies particularly during the summer when it is hot. Flush water through the floor drain, so that the water trap fills up again, and the bad smell will disappear in a short while.
