楼房里的住户,冲洗小便用水,洗手又要用水,如把洗过手的水用来冲洗小便岂不省水?为解决这个问题,我曾将蹲式大便器和洗手盆的管路进行改动,实现了一水两用。现将具体做法介绍如下。将洗手盆的排水管,由原来直接与排水横支管连接,改为在接近地面处与蹲式大便器上面的冲洗 Households in the building flush their urine with water, wash their hands and use water again, such as washing water to wash their hands, not to save water. In order to solve this problem, I have changed the pipes of the squat toilet and wash basin. Achieve a dual purpose. The specific practices are described below. The washbasin’s drain pipe was connected directly to the drain lateral pipe and was flushed to the floor above the toilet stool.
