The lower water collection tank is connected to the underground drainage pipe; the water collection selection valve is respectively provided with a water inlet pipe and a waste water pipe, and the water collection selection valve is connected to the lower water pipe through the waste water pipe, and is connected to the central water collection tank and the lower water collection pipe respectively through the water inlet pipe. Water tank connection.

The upper water collection tank, the middle water collection tank and the lower water collection tank are respectively connected to the toilet through the flushing pipe, and the toilet is connected to the downwater pipe through the toilet pipe.

The beneficial effects of the utility model are:

The water-saving device for residents of this building has a simple structure, reasonable design, easy installation, one-time installation, permanent benefit, and good water-saving effect. The collected rainwater can be stored step by step in each water collection tank, and the lower residents can selectively collect the laundry water or bath water of the upper residents through the water collection selection valve installed on the upper floor plate, and the water that meets the requirements Enter the water collection tank through the water inlet pipe for secondary use; the water that does not meet the requirements enters the downpipe through the waste water pipe for discharge. The promotion and use of this water-saving device will undoubtedly produce positive economic effects for families and bring positive social effects to the country.
