The advantages of Rainplus®
When compared to conventional systems, Rainplus® requires a lesser number of roof outlets and allows a substantial reduction in pipe diameters, in the number of fittings required and the number of downpipes: this results in savings of up to 80% on vertical pipes and from 20% to 30% across the entire system.
The roof outlets are connected to single horizontal collector pipes that are fitted without fall and the downpipes are positioned anywhere along the building perimeter thus avoiding interference.
When in operation drainage pipes flow at 100% full over the entire system, draining velocity is therefore greater resulting in the self cleaning action of the pipework.
The ease in directing the pipes to storage tanks makes the collection of rainwater easier for reuse in irrigation systems, fire ponds and tanks for non-potable uses in general.
Time and labour saving
Construction programmes are accelerated due to reduced installation times and less groundwork is required due to the reduced number of embedded pipes.
Increased design flexibility
Complete control over downpipe location and absence of embedded pipes gives increased design flexibility of the siphonic system.
The Valsir Rainplus® system and HDPE are produced with completely recyclable materials which, at the end of their useful life can be recovered. The production processes employed are energy efficient and of reduced impact. Valsir has adopted the Green Building principles in terms of respect for the environment and conservation of resources, pipes and fittings are in fact certified by the prestigious Singapore Green Building.
