Abstract:
A unitary removable barrier for installation in a cylindrical water line to selectively block the water line to the passage of water therethrough, said unitary removable barrier being composed of a single piece body having at least one cylindrical section having at least one cross-sectional area, longitudinal axis and sized to receive an upstream pipe and downstream pipe of said water line and a planar disk located within said at least one cylindrical section and which is characterized as being of circular circumference which completely blocks said cross-sectional area, having a diameter which is substantially perpendicular to said longitudinal axis and which is selectively removable from cylindrical section thus removing said barrier to said water line, said planar disk being provided with a wire embedded therein, wherein said wire is removable from said planar disk wherein removing said wire causes said planar disk to be removed from said cylindrical section, said wire is embedded within said planar disk from the geometric center of said planar disk to its circumference along a helical path.
