发明名称 Water recycling device for flush toilet use
摘要 A compact, modular gray water recycling system includes a control and reservoir unit for storing gray water, which is received from a source such as a sink drain, and pumping it to the household toilet as necessary. The single unit houses a pump, flow signals, filters, and an overflow. The system may also utilize a second storage reservoir and separate control unit for added gray water storage. The secondary storage and control units may also be adapted to receive water from an outside source such as rainfall runoff.
