2. Thread the isolation valve onto the guide nipple. Ensure that the
valve stem is positioned so that when the Flo-Tap is installed, the
insertion rods will straddle the pipe and the valve handle will be
centered between the rods (see Figure 8). (Note: Interference will
occur if valve is located in line with the rods.)
