As is clear from the above description, in the water supply / hot water supply pipe of the present invention, the header is installed under the building floor and the branch pipe from the header is routed under the building floor. When connecting the branch pipes to the water plumbing equipment, the number of times that each branch pipe is started up on the floor is only one, and the piping work can be performed relatively easily. Also,
It is possible to reduce unnecessary branching of the branch pipe as in the related art, to reduce the length of the branch pipe as much as possible, and to reduce the total length of the pipe.

Further, since the main pipe and the branch pipes are suspended and supported, even if a water hammer occurs, the main pipes and the branch pipes are not exposed. The gap between the floor pipe and the branch pipe can prevent the main pipe and the branch pipe from colliding with the floor material, thereby reducing noise.

In addition, since the height of the holding member, ie, the header held by the holding member, can be adjusted within the range of the bolt insertion hole which is a long hole of the leg member, the height can be adjusted to the height of the underfloor space. Thus, the height position of the main pipe or the branch pipe can be appropriately adjusted, and the workability can be further improved.
