2. Description of the Related Art Conventionally, a housing adopting a fork branching method in which a branch pipe sequentially branched in a branch from a main water supply pipe or a main hot water supply pipe via a joint is connected to a faucet of each water circulating facility. There are known water supply and hot water supply pipes. However, in such a forked branch method, there are inconveniences such as a large number of connection points, a high occurrence of water leakage due to poor construction, and a large change in flow rate when the water plumbing equipment is used at the same time.

[0003] In recent years, branch pipes that are branched from a main water supply pipe or a main hot water supply pipe via a header to a faucet of each water supply facility have been recently applied mainly to apartment houses and the like. Water supply with a header method that connects one to one
Hot water supply piping has become widespread. In such a header method, compared with the fork branch method, the number of connection points is small and water leakage due to poor construction can be significantly suppressed, and the flow rate change is small when simultaneous use of water circulating equipment, stable water supply, Hot water is available.

[0004]

When a water supply / hot water supply pipe adopting the above-mentioned header method is to be constructed in a two-story detached house, for example, a header is installed on the first floor where water supply facilities are often provided. The main water supply pipe and main water supply pipe led to the first floor are branched into a plurality of branch pipes via the header, and a part of these branch pipes is set up on the second floor and connected to the corresponding water supply facilities on the second floor. I am trying to do it.

When a plurality of water supply facilities are provided on the second floor, a sub-header is installed on the second floor, and the branch pipe raised to the second floor is further connected to a plurality of branch pipes via the sub-header. Branches are made so that these branch pipes are connected to the corresponding water supply facilities on the second floor.

However, for a multi-family house, the piping described above causes various inconveniences. That is, in a multi-family house, watering facilities of substantially the same type are often provided for each household so that they can live separately.

For this reason, the branch pipe from the main header installed in one household as described above is connected to the water plumbing equipment of another household, and the branch pipe from the main header installed in one household is If a branch pipe from this sub-header is connected to a sub-header installed in another household and connected to a water-circulating facility of the other household, the pressure loss may increase and an appropriate amount of water may not be secured. In addition, when only one main water supply pipe is connected to the water meter and the usage fee for multiple households is billed collectively as a water charge, when households are separated for each household, It was inconvenient.

Accordingly, an object of the present invention is to provide a header type water supply / hot water supply pipe for a multi-family house, which can solve the above-mentioned problems and realize stable and independent water supply / hot water supply for each household. And

[0009]

In order to solve the above-mentioned problems, a header type water supply / hot water supply pipe of the present invention is separately introduced to each household in a multi-family house provided with water supply facilities for each household. The main water supply pipe and the main hot water supply pipe are branched into a plurality of branch pipes via headers respectively installed for each household, and these branch pipes are connected to corresponding water supply facilities.

[0010] Each header is installed under the floor of each household, and the main water supply pipe, the main hot water supply pipe, and the branch pipes are routed under the floor. In addition, each header is installed under the floor at a location where water-related facilities such as utilities in each household are concentrated. further,
The main water pipe leading to each household is connected to a different water meter.
