PIPE SHAFT OF WATER SUPPLY PIPE LINE

摘要

PROBLEM TO BE SOLVED: To reduce the kinds and number of required members by connecting a hot water generator to one of two pipe connection parts of a special water supply branch coupling while a water supply distributor to the other through a flexible synthetic resin pipe, respectively, and fixing the lengthwise part of the special water supply branch coupling in parallel with the surface of a floor. SOLUTION: One of ends of branch pipe composed of short pipe and elbow is connected to a main pipe 10 for supplying water while the other end thereof is connected to one of ends of water supply meter 30 with a pressure reduction valve interposed therebetween. To the other end of the meter 30 a lengthwise end of a special water supply branch coupling 40 is connected with a check valve interposed therebetween. To two pipe connection parts of the coupling 4 a resin pipe communicated with a water supply branch device and a resin pipe 60 communicated with a hot water generator are connected respectively. The coupling 40 is retained in its lengthwise part by a fixing fitting 70 and fixed in pallarel with the surface of a floor.
