Cutting edge water saving technology
Unique global technology for saving water. The patented technology of fin collects quantities of clean, unused water which are wasted when the tap is left running in the intervals between uses, e.g. when washing hands, shaving, brushing teeth or when waiting for the hot water to come which is a source of great waste of drinking water, especially during the winter months.
