The arrangement has a main supply pipe and several branch pipes. The main supply pipe consists of several branch pipe sections (11) with external thread (24,26) at one end. One end has a right-hand thread, and the other end has a left-handed thread. Each joint has a right/left nut (12). The branch pipe sections are made of plastics, and the branch pipes (17.1,17.2) are formed in outlet sockets (16.1,16.2). Injection-moulded branch screw connections (19.1,19.2) of metal, esp. bronze, brass, or other rust-proof metal are located in the sockets. The screw connections have a right-hand thread and a sealing seat (19.1).
