ABSTRACT:
A telescoping drain line for connecting recreational vehicles to a sewage system has telescoping rigid wall drain pipes having a plurality of pipe sections telescoping one within the other. A flexible hose extends through the telescoping pipes and out each end thereof and has means for attaching to a recreational vehicle drain at one end and into a sewage line opening at the opposite end thereof. The flexible hose is attached at each end of the telescoping rigid wall drain pipe to prevent the flexible pipe from collapsing or coming out of the rigid pipes. The flexible pipe will fold within the telescoping pipe for storage of the drain line.
