Wet closed bottom traps

 

— the water seal ensures that odours are cut off by creating a water plug — a certain amount of water remains in the water intake and closes the penetration of odours from the sewer. Wet shutter is recommended to be installed in shower trays and cubicles that are regularly used. Otherwise, the water in it dries out or stagnates and the water seal itself becomes a source of an unpleasant odour.
