Geberit Pluvia siphonic roof drainage

The system with negative pressure

Fewer pipelines, more performance

Geberit has been setting standards for roof drainage for decades with the Geberit Pluvia syphonic roof drainage system.

With Geberit Pluvia:

  • Fewer roof outlets are required due to high discharge rate
  • There is an increased planning flexibility by saving on stacks
  • Maximum use of space due to horizontal pipelines without slopes

Sophisticated details, high-quality system components and Geberit as your partner reliably ensure safety, durability and smooth operation.

The right technology ensures a better result

Syphonic roof drainage

New for Pluvia

Improved handling

  • More compact construction and an ergonomic design for all Geberit roof outlets compared with predecessors
  • New rotating lock bar for easy installation and maintenance
  • Extra-long Geberit HDPE straight connector for higher insulation thicknesses

Simpler planning and calculation

  • Geberit ProPlanner software with plug-in for Autodesk® Revit® for hydraulic calculation
  • Complete BIM data available
  • Geberit Pluvia Outlet for concrete roof with bitumen as water-bearing level

Example 1: For concrete roofs with bitumen roof foil, Geberit Pluvia has an extra-large contact sheet to provide a better connection.

  • Geberit Pluvia Outlet for insulated roof with vapour barrier connection and roof foil as water-bearing level

Example 2: Lightweight roofs benefit from the low static load thanks to Geberit Pluvia. The long connection pipe allows even high insulation thicknesses to be overcome.

  • Geberit Pluvia outlet flanged in the gutters

Example 3: Thanks to its compact design, Geberit Pluvia is also suitable for installation in gutters.

  • Geberit Pluvia outlet installed with “weight-bearing” set

Example 4: For weight-bearing concrete roofs with bitumen roof foil, the height of Geberit Pluvia can be adapted with a supplementary set.

  • Geberit Pluvia fastening system
  • Fastening points only required on the building structure every 2.5 metres
  • Can be installed easily using a hammer thanks to the universal tension wedges
  • Fastening with electrofusion tape enables anchor points to be determined subsequently
  • Ideal for lightweight roofs since there are only weak forces acting on the building structure

The proven Geberit HDPE pipes made of HDPE are easy-to-install connections with long-term stability, which ensure the reliable drainage of roof water.
