Syphonic Roof Drainage

Solution Overview

Total Eden is the exclusive distributor for the Valsir RainPlus siphonic large scale roofing rainwater drainage system.  The system uses the building height as the driving force to generate high speed flow rates thus maximizing drainage efficiency. RainPlus allows the entire flow to be directed to any part of the building thus enabling the most modern rainwater harvesting systems to be installed.

The Rainplus siphonic system is made up of special roof outlets designed to be connected via Valsir HDPE pipes & fittings which are sized to work under negative pressures at high flow rates.  This is possible due to the configuration of the outlets which prevent air from entering the pipes when the design rainfall intensity is reached.

Benefits

Valsir technology fully meets the increasing levels of rainfall and ensures total drainage safety for medium to large size buildings.  It allows maximum water drainage performance with the lowest levels of water accumulation on the roof. The system incorporates an anti vortex plate which prevents air entering the pipes allowing vastly increased flows 10 times faster compared to conventional systems. Allows for a wide range of drainage flows  and low noise levels.
