COUPLING BOARD STRUCTURE IN PIPE SYSTEM

PROBLEM TO BE SOLVED: To solve problems of a conventional coupling board, whose faucet body or fitting part with a resin pipe are made of metal such as brass so as to take a high manufacturing cost and become heavy, which requires careful fitting works by an extent of the weight in being fixed to a wall surface such as securing a sufficient wall thickness and preparing strong fitting devices, thereby increasing the construction cost and material cost in the fixing of the coupling board to the wall. SOLUTION: This pipe system is so constituted that the coupling board for supplying feed water from the feed water supply pipe to water using devices in a living space is disposed in a necessary position and a water feed pipe of the water using devices is detachably connected to the coupling board. The coupling board is so constituted that the faucet mechanism part and a discharge part are connected to each other and the faucet body formed by molding the faucet mechanism part of resin is stored inside a coupling board casing.
