发明名称 Tear-out coupling with embedded wire
摘要 A unitary removable barrier for installation in a cylindrical water line to selectively block the water line to passage of water therethrough. The unitary removable barrier is composed of a single piece body having at least one cylindrical section sized to receive upstream and downstream pipes of the water line. A unitary planar disk is molded with the cylindrical section and is of a circular circumference which completely blocks the water line when in place but which is selectively removable from the cylindrical section thus removing the barrier to the passage of water through the line.
