Abstract
A method of restricting fluid flow through a pipe. The method comprising installing an anchor through an opening in a wall of the pipe, engaging a portion of the wall with a foot of an anchor, securing a head of the anchor to the pipe, placing a saddle between a bottom surface of the head and an outer surface of the wall of the pipe, and inflating an inflatable plug coupled to the anchor. When securing the head of the anchor to the pipe, the head remains partially outside the pipe.
