How it works

Flow-optimised fittings allow for a cost-effective configuration of stacks perfect for high-rise structures. With Geberit’s range of sophisticated, high-performance fittings, the Geberit Sovent System creates and maintains a continuous column of air within the discharge stack. This eliminates the need to install separate vent piping systems (for up to 4 meters).
