The present invention relates to a water-saving circulation piping apparatus. According to the present invention, installation of the piping apparatus that is disposed between a water valve and a hot water storage container is facilitated for improved workability, water stored in the hot water storage container is allowed to circulate in piping between the water valve and the hot water storage container in a state where the water valve is closed so that piping freezing in winter can be prevented, and the circulating water maintains a constant temperature and hot water is promptly discharged when the water valve is opened so that water consumption can be reduced. The present invention is a piping apparatus that is disposed between the water valve which controls supplied water discharge and the hot water storage container which is filled with the hot water. The present invention includes a water piping portion that is disposed for one side to be connected to the water valve, a pair of separated and hollow flow paths being formed therein; connection piping that is disposed for one side to communicate with one of the pair of flow paths of the water piping portion; a circulation driving pipe portion on which a circulation pump is mounted, the other side of the connection piping being connected to the circulation pump; and a supply pipe portion that is disposed to be connected to the circulation driving pipe portion and the hot water storage container, so that the hot water discharged from the hot water storage container circulates and flows back into the hot water storage container when the water valve is closed. |
