Keep blades moving: Watch for full ribbons of trim from both faces.

Heating the pipe: Make firm, even contact with heating iron, then use neutral pressure.

The melt: This varies according to pipe size and rating; for SDR 17 in smaller sizes (3”, 4”, 6”) look for a melt of 1/8” or slightly less.

Entry: Breaking out the old pipe. Note minimal excavation.

Feeding the cable: In many cases, it is not necessary to use the duct rod to pull cable through the line. Here the pull is downhill, relatively short, and steep.

Positioning the new pipe: Making the approach as direct as possible.

Pulling end: Cribbing the wall to provide even support for the resistance plate.

Ready for tension: Keep pressure gauge visible.

Feeding the pipe: It’s important to give the bursting head a good start.

Well underway: After a good entry, pipe often needs little attention.

End of the pull: Removing the cotter pin from the clevis bolt.

“Bumping”: Fuse enough pipe to have this option when the pull is done.

Ready to connect: When possible, give plenty of cutoff length behind the head. (Note brass water supply line, which was easily avoided with the TRIC system.)
