Abstract:
A unitary removable barrier for installation in a cylindrical water line to selectively block the water line to 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, when intact, blocks water flow from said upstream pipe to said downstream pipe but which is capable of being punctured whereupon said planar disk allows for the passage of water from said upstream pipe to said downstream pipe and means provided therewith for puncturing said planar disk from a location exterior to said cylindrical water line, said means for puncturing said planar disk comprises a jacket and wire, said jacket and wire having a first end terminating at said planar disk and a second end terminating outside of said cylindrical water line.
