PROBLEM TO BE SOLVED: To provide a piping system for a detached house in a header construction method, with which piping works can be conducted without depending upon the construction works of a building skeleton and which is inspected and repaired easily. SOLUTION: Headers 8a and 8b, to which a main water supply pipe 4 is connected, are installed on the outside from an indoor wall surface, and branch pipings 10 laid from the headers, to each water supply section are inserted into an opening between a building sill 11 and a floor section 12 and introduced to an underfloor section 12a. The headers, to which the main water supply pipe is connected, are mounted on the outside from the indoor wall surface, and the branch pipings laid from the headers to each water supply section are inserted to the floor section, on the side inner than the building sill or an opening section formed to a ceiling section, and introduced to the underfloor section or an attic space 13a. A casing 17, in which a hot-water supply machine 9, is housed, is made to swell and secured so as to be positioned on the side inner than the building sill.
