Claims
- 1. 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 disc molded with 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 said cylindrical section both from said upstream pipe and downstream pipe thus removing said barrier to said water line.
- 2. The unitary removable barrier of claim 1 wherein when said planar disc is removed from said cylindrical section, a ledge of said planar disc remains providing a circular opening within said cylindrical section substantially equal to the inside diameters of said upstream and downstream pipes.
- 3. The unitary removable barrier of claim 1 wherein said planar disc is provided with at least one score line to facsilitate its removal from said cylindrical section.
- 4. The unitary removable barrier of claim 3 wherein said at least one score line comprises a score line at the circumference of said planar disc.
- 5. The unitary removable barrier of claim 1 wherein said planar, disc is characterized as having an upstream face and downstream face and a first tab molded to said upstream face and a second tab molded to said downstream face whereby said planar disc is removable as a barrier to said cylindrical water line by applying sufficient pulling force on either tab to separate said planar disc from said at least one cylindrical section.
- 6. The unitary removable barrier of claim 5 wherein said first and second tabs are molded to said upstream face and downstream face of said planar disc, respectively, along score lines configured within said planar disc.
- 7. The unitary removable barrier of claim 6 wherein a pull line is appended to said planar disc which extends outside of said cylindrical water line such that by pulling on said pull line, said planar disc ruptures along said score line whereupon said planar disc is removable from said water line.
- 8. The unitary removable barrier of claim 7 wherein said pull line is appended to either or both said first or second tab.
- 9. The unitary removable barrier of claim 2 wherein said at least one cylindrical section is designed to frictionally receive said upstream pipe and downstream pipe of said water line.
- 10. The uniting removable barrier of claim 1 wherein said upstream pipe and said downstream pipe substantially abut on another at said unitary removable barrier.
- 11. 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 a cylindrical section having a cross-sectional area, longitudinal axis and sized to frictionally receive an upstream pipe and downstsream pipe of said water line, each of said pipes having substantially equal inside diameters, said upstream pipe and said downstsream pipe substantially abutting one another at a planar disc molded with said cylindrical section 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 said cylindrical section both from said upstream pipe and downstream pipe thus removing said barrier to said water line.
- 12. A unitary removable barrier for installation in a cylindrical water line to selectively block the water line to passage of water therethrough, said unitary barrier being composed of a single piece body having a first cylindrical section of first diameter and a second cylindrical section of a second diameter and a longitudinal axis passing through both first and second cylindrical sections, said first cylindrical section sized to receive an upstream pipe and said second cylindrical section sized to receive a downstream pipe of said water line and, when said upstream pipe and said downstream pipe are received, respectively, by said first and second cylindrical sections, a disc molded as a unitary piece with said first and second cylindrical sections is positioned between said upstream pipe and downstream pipe to completely block said water line to the passage of water between said upstream pipe and downstream pipe, said disc being completeley removable from said water line both from said upstream pipe and down stream pipe.
- 13. The unitary removable barrier of claim 12 wherein said disc is characterized as having a diameter substantially equal to the diameter of said downstream pipe.
- 14. The unitary removable barrier of claim 10 wherein said disc is provided with at least one score line to facilitate its removal from said water line.
- 15. The unitary removable barrier of claim 6 wherein a pull line is appended at one end to said planar disc and is appended to a magnet at its other end.
