The pipes 44, 56 and 57 are made of a steel pipe with ends in the longitudinal direction threaded with steel pipe threads. A connecting part of the pipe 44 and the flush valve 2 is connected by a union joint 43 and an adapter 41 with the steel pipe threads threaded. A connecting part of the pipe 44 and the pipe 56 is connected by a 90-degree elbow 55 with steel pipe threads threaded. A connecting part of the pipe 56 and the pipe 57 is connected by a union joint 61 and an adapter 59 with steel pipe threads threaded. COPYRIGHT: (C)2008,JPO&INPIT
