Plumbing and drainage fittings  

Check the condition of the plumbing fittings and their joints and clean the sewer drains and water seals regularly. That way, you can avoid unpleasant odours and reduce the risk of water damage. If a water tap is leaking or a drain becomes completely blocked, submit a defect notification.  

Water seals and floor drains  

If the drain in your kitchen or bathroom sink is starting to get blocked, clean the water seal.  

These can be signs of a blocked pipe:  

  • The sewers smell unpleasant.  
  • The sewers make strange noises.  
  • The water level in the floor drain and toilet bowl often rises.  

If cleaning the kitchen drain requires opening the water seal, submit a defect notification. Residents may not open the kitchen water seals by themselves.  

 If you need to open the water seal in the bathroom, make sure that after you have completed your work you tighten the parts of the water seal sufficiently so that the seal does not leak. If the drain becomes completely blocked, submit a defect notification.  

Sewage bacteria can enter the indoor air of the apartment from a dirty floor drain. Clean the floor drains in wet spaces at least once a month.  

How to clean a floor drain  

  1. Wear protective gloves. Do not use the cleaning supplies for other cleaning tasks.  
  2. Lift out the grid.   
  3. Remove hairs and other debris.   
  4. Wash the floor drain and its parts with warm water, detergent and a brush.   
  5. Disinfect the floor drain.  

Using a filter (available in hardware stores) that collects hair and other loose debris and which is installed under the lid facilitates keeping the floor drain clean.
