Wastewater drains and floor drains

The sewer system is not a substitute for the dustbin or the refuse sack, for it clogs easily. You must not use the drain to dispose of solid refuse, solid food scraps, coffee grounds, cigarette butts, diapers, sanitary napkins, condoms, cotton sticks, textiles, wrapping paper or newspaper, hot molten grease, solvents, paints or other chemicals, oil, petrol, medicines, control substances, hazardous wastes, construction wastes, sand, earth, or any other substances which might clog it.

It is up to the tenant to clean the stench traps of the drain points and the bathroom floor drain. The floor drain gathers hair, among other things, which will clog it in time. Every drain point has a stench trap, which, if allowed to dry, will let the stenches into the flat. If you leave the flat for a long time, you can deter evaporation by pouring a little cooking oil into the traps. If you don’t know how to clean the stench trap, ask maintenance for advice. After the cleaning, make sure that you have not left the stench trap leaking.

The floor drain gathers hair in particular, which is why it needs to be cleaned regularly. The grating is easy to pry loose with a screwdriver, for example. The hair and other refuse can easily be removed by means of a small plastic bag, for instance. Wash the floor drain and its parts with a brush using warm water and detergent. Press the grating back on. If the plug of the cleanout hole leading past the stench trap straight to the sewer duct has come loose, letting the sewer stenches freely into the room air, you must give a notice of defects.
