A distribution line for saving cold and hot waters is provided to improve the repairing work by only closing the valve of the water-leaked part and preclude the freeze from occurring in winter through the control of the distribution device. A distribution line for saving cold and hot waters comprises a guide pipe(11); and cold and hot water pipes(12,13) inserted in the guide pipe. One side of the guide pipe is fixed by a Ф-shaped fixing device(26) at a distribution device panel(24), and the other side of the guide pipe is combined at a variable distribution groove formed at a lower panel(35) of a water panel box(3). One side of the cold water pipe is combined at a unit cold water control valve(223) of a cold water distribution device(22) by a sealing nut(224). The other side of the cold water pipe is combined with a connection member(36). One side of the hot water pipe is combined at a unit hot water control valve(233) of a hot water distribution device(23) by a sealing nut(234), and the other side is combined with another connection member(37) installed in the water panel box. An internal diameter(D) of the guide pipe is 2~2.5 times larger than an external diameter(d) of the cold water pipe and an external diameter(d') of the hot water pipe. |
