SitaVasant – Attikaentwässerung der rasanten Art

Emergency drainage included. A gully with two separate inlets that function independently of each other – that is the special feature of the SitaVasant Double. Main drainage and emergency drainage are combined in one gully and only require one penetration in the parapet. In the event that the water level on the roof rises to the emergency drainage level, an emergency drainage channel, which is 35 mm higher than the main drain, discharges onto a freely floodable area. It is simply inserted through the gully and the stainless steel connection pipe. As it sits elevated in front of the gravel trap, it forms an autonomous emergency drainage unit that remains functional even if the main drainage system becomes blocked due to the entry of leaves or foreign bodies or is simply overloaded by heavy rainfall.
