Geberit PE SuperTube Hydraulically optimised drainage for high-rise buildings
All the components of the Geberit PE SuperTube system are designed to work together perfectly, allowing space-saving waste water installations in high-rise buildings.
Geberit PE SuperTube eliminates the need for a parallel ventilation pipe, creating more residential and floor space.
Using smaller diameter pipes allows smaller pipe ducts while still maintaining a high discharge capacity of 12 l/s when using pipes with d110.
Geberit SuperTube quick overview Here’s how the drainage system works
Conventional drainage systems in high-rise buildings generally require a lot of space for pipes with d160 and additional secondary ventilation pipes with d90. There also needs to be enough space below ceilings for horizontal pipes to have the correct slope. The discharge capacity of a conventional system is 12.4 l/s.
The hydraulically optimised Geberit SuperTube drainage system requires less room, creating additional living and working space. Geberit SuperTube technology creates a continuous column of air in the discharge stack. This allows the stack to reach a discharge capacity of 12 l/s with smaller pipes d110 and without any additional secondary ventilation. Horizontal pipes can be installed without a slope for up to 6 metres.
Perfect interplay
The outflowing water is set in rotation in the Geberit PE Sovent fitting.

Three fittings make the crucial difference
Geberit PE Sovent fitting d110
The optimised product geometry of the Geberit PE Sovent fitting guides the water into the stack and sets it in rotation, which causes it to press against the pipe wall. The resulting annular flow creates a stable, continuous column of air on the inside, which facilitates a discharge capacity of 12 l/s.
Geberit PE BottomTurn bend
With the Geberit PE BottomTurn bend, a change in direction causes the wall of water to break and the annular flow to become a layered flow without disrupting the column of air. This change significantly reduces impulse losses compared with conventional solutions.
Geberit PE BackFlip bend
The twisted Geberit PE BackFlip bend causes the layered flow of water to swirl, which allows it to rotate through the vertical pipeline as it drains away in an annular flow. The inner air column in the subsequent stack is maintained.
