ABSTRACT:
A method for water leakage prevention in a portion connecting a first pipeline to a second pipeline having one end thereof in communication with a portion of the first pipeline is provided. This method includes the steps of passing elastically deformable drawing means from the other end of the second pipeline to one end of the first pipeline; engaging an impermeable cut-off member, having an expandable hose portion and a flange portion provided integrally with one end of the hose portion, with the drawing means at one end of the first pipeline at the hose portion; drawing the cut-off member into the first and second pipelines by drawing back the hose portion of the drawing means toward the other end of the second pipeline; and disposing the cut-off member in the first and second pipelines, so that the flange portion is positioned within the first pipeline and the hose portion extends within the second pipeline.
