A range of rainwater drainage systems

RwpClearflow siphonic drainage

Using our extensive knowledge of the siphonic industry RwpClearflow has developed a high flow capacity siphonic rainwater outlet capable of taking flows up to 46 l/s per outlet - nearly twice the amount of some earlier siphonic outlets.

The product has been developed to work with all modern day construction methods and material types, allowing the outlet and adjoining siphonic system to be used in virtually any new build or refurbishment.
