Water-saving device

A large quantity of water is wasted from hot water outlets while waiting for the hot water to arrive. Using the Aqua-technique water saver system, this water is re-circulated, saved and reused, so that it is not lost.

The system operates through a thermally operated valve that has been designed for this purpose. It is attached to the hot supply pipe, directly beneath each basin.

There is no need to change or alter the existing taps. Installation of the water saver is quick and easy. Using this system, it is estimated that around 20,000 L of water per year could be saved per tap, based on 6 L per run x 10 openings per day.

The system can be fitted to any plumbing system, ranging from small one-room apartments up to large 100+ room hotels etc.

How it works is that cold water that normally runs down the drain once the hot water outlet is opened is either diverted to a header tank, or simply fed via a pressure-reducing valve back into the hot or cold water pipe, so that the saved water can be stored and reused.

To support the system, Aqua-technique has designed the Sinclair Kinetic valve and systems that can be easily installed to any type of new or existing plumbing system. The valve is quite simply operated by the inherent water energy when the faucet is opened, and a flow induced.

A quick-fit-pipe is then run to the nearest water closet, or returned to heater boiler, etc. Alternatively, the pipe can be run to the W/C cistern so that saved water can be used for flushing toilets rather than being diverted to cold faucets. Some plumbing systems may require a small pressure tank, to be added to the system, which includes provision of a pressure control valve so the saved water can be returned to the nearest cold water supply pipe.
