In order to solve this problem, there is also a laying method in which a pipe is routed inside a room to increase the number of pipes. However, since the pipe route is exposed inside the room, a problem in design arises. Furthermore, it is necessary to tighten the water supply valve during the renovation work, and the longer the construction period, the more inconvenience is given to consumers. In addition, if the piping connection unit is provided in advance, the place where the water end equipment can be moved or added is fixed, and it is necessary to provide the connection unit in a place that is not currently used,
Plumbing takes time and money.

The problem to be solved in the present invention is that the hanging work of walls and floors accompanying the laying of water supply and drainage pipes by renovation or the like is greatly reduced, and consequently the work can be performed in a short work period and at low cost. Another object of the present invention is to provide a method of laying a water supply / drainage pipe and a piping device which can maintain the water supply and drainage equipment at an arbitrary position to some extent without inconvenience to consumers during the renovation work.

[0005]

Therefore, there is no need to suspend the floor or wall over the entire surface, and the construction can be performed at low cost and in a short construction period. In addition, there is no inconvenience to consumers during the renovation work, and the design after the work is maintained.

Since the laying position of the water supply pipe and the drainage pipe or the drilling position is displayed, there is no drilling at an incorrect position, and the reliability of the construction is improved.

Since the water supply pipe and the drain pipe are installed in parallel with a predetermined distance to the wall where the peripheral equipment is expected to be installed, and a plurality of branching tools are installed in the water pipe and the drain pipe, It becomes possible to install the end equipment around the water at any position on the expected wall surface.

Since the water supply pipe is a flexible pipe, the connection between the water supply pipe and the connector can be made on the floor, and the workability is improved. Further, since the flexible pipe can be cut to a predetermined length, the connection work becomes easy, and the pipe can be easily set under the floor, and the workability is improved.

In a water supply system having a branch header,
When the water end equipment is not installed, the water supply pipe and the branch header are not connected, so that there is no deterioration of the water supply pipe and the reliability in quality is improved.

In a water supply system having a branch header,
If the end device around the water is not installed, by closing the on-off valve installed between the water supply pipe and the branch header, the water supply pipe is not deteriorated and the reliability in quality is improved.

In the equipment having the branch header,
Since the lid is provided at the end of the water supply pipe, insects, dust and the like do not enter, and the reliability in quality is improved.

Since the water supply / drainage pipe is laid under the floor of the closet or behind the wall, the closet which is likely to be an empty space when a person requiring care is generated can be effectively used as a renovation space for care.

Since the water supply and drainage pipes are laid under the floor of the second floor or behind the wall, it is possible to expand the water supply on the second floor, which has a relatively strong demand for remodeling due to changes in lifestyle such as the growth of children, at low cost and in a short construction period. Becomes

Further, in an indoor piping device, a water supply / drainage pipe is concealed and installed under the floor, behind a wall, or the like, so that an arbitrary position of a surface material covering the water supply / drainage pipe can be opened. To provide a connection tool that is connected to the, the connection tool to connect the water supply and drain pipe and the water around terminal equipment,
For the first time when adding water-end equipment, it is possible to drill holes only at the expansion points, and as a result, it is not necessary to hang the floor or wall over the entire surface, making construction possible at low cost and in a short construction period . In addition, there is no inconvenience to consumers during the renovation work, and the design after the work is maintained.

Since the connecting member is provided with a cover member for covering the opening, the underfloor and the floor or the back of the wall and the surface of the wall can be separated.
Garbage and insects behind the wall do not enter. In addition, the airtightness of the room is maintained.

Since a plurality of branching tools are provided in the plumbing pipe,
An opening can be provided at an arbitrary position on the water supply / drain pipe so that the water supply / drain pipe can be connected to the terminal device around the water.

Since the water supply pipe is made of a flexible pipe and can be cut, the water supply pipe can be cut to a required length and connected to the connecting device, so that the connection work becomes easy and the pipe can be fitted under the floor or the like. The workability is improved.
