Emergency overflow / weir element DN90mm for roof drains with a capacity of 25l/s, overflow height 65mm (Pluvia) 359.101.00.1

Emergency overflow for roof drainage systems

This overflow element, with a diameter of 90mm, is an integral part of the Geberit Pluvia system – an advanced solution for vacuum roof drainage. Its task is to provide additional safety and efficiency in the event of extreme rainfall, enabling effective drainage of excess water from the roof surface. The product is dedicated to both professional installers and building owners who appreciate reliability and durability.

Functionality and application

The emergency overflow plays a key role in the Pluvia system, especially in situations where the capacity of standard roof inlets is insufficient. Thanks to its design, it allows for the safe drainage of a larger amount of water, minimizing the risk of system overload and potential damage. This is particularly important for large roof areas, buildings with complex geometry, and areas prone to heavy rainfall. It can be used as a supplement to existing Pluvia installations or as an integral part of newly designed systems.
