Putting trash, food waste, and frying fat in the drain can cause an unwanted blockage in your home’s plumbing. Therefore grease or other waste should not be placed in the drain.

Grease blockage is one of the most common causes of sewer blockage. In the worst case the blockage can cause water damage. Blocked drain and food waste can also attract rats and cause an unpleasant odor nuisance.

Signs of a sewer blockage are, for example, a strange noise from the sewer, a rise in the water level often from the floor drain and the toilet, and an unpleasant odor.

If you notice that the drain is blocked and you cannot open it by yourself, report the fault via OmaSATO or contact the maintenance company directly.

You can flush down:
  • toilet bowl water: toilet paper and human waste
  • dish washing waters and laundry waters
  • water used for washing or cleaning
