2.3.3 Operating mode
In most drains, the ingression of sewer gases into rooms with drains is
prevented by an odour trap with a water seal. If the drain has not been
used for a long time, the water seal can evaporate and this may lead to
odour nuisance.
Fig. 1: Mode of operation of the odour trap
The odour proof odour trap prevents the ingression of sewer gases,
even after the water seal has evaporated. The odour proof odour trap is
equipped with two shutter valves, as can be seen in the lower part of
the graphic. If the water seal has evaporated, the shutter valves close
and hold the sewer gases back in the drain.
