double drain stopper by melis guctas from usa

Double drain stopper is a product, which enables the user to be aware and to choose their own gray water to reuse, and black water to send the sewage. As the user gets to interact with the double drain stopper more, he/she will also become more considerate of reusable water that is wasted everyday. By double drain stopper, gray and black water will be sent to two different pipes; one leads to the sewage, other leads to a filtered reservoir.
The mechanisms of both drain stoppers work exactly like a simple push pen turn mechanism.
