Characteristics of excellence

Local regulations or standards on the design of rainwater systems may require emergency systems (also known as overflow systems) to be provided that are capable of draining unexpectedly intense rainfall that exceeds the design rainfall level.

Valsir supplies a patented product that allows a Rainplus siphonic outlet to be transformed into an emergency siphonic outlet by simply adding an Overflow Kit that is adjustable in height and capable of maintaining the same drainage performance.

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 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.

Rainplus requires a lesser number of roof outlets and allows a substantial reduction in pipe diameters, this results in savings of up to 80% on vertical pipes and from 20% to 30% across the entire system.

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.

Trusted Drainage System

The Rainplus siphonic drainage system is made up of special outlets that are patented, designed and tested to American Standard ASME A112.6.9 and European Standard EN 1253 and connected to HDPE high density polyethylene pipes. The outlets also incorporate special components that allow installation on any type of roof and waterproofing sheet.
