For my 165' of 3" conduit, I used a shop vac and a spinning reel. Tied the
handles of a plastic Safeway shopping bag to the 8# test fish line, released
the reel, and using the blower direction on the shop vac, blew the line
through in about 5 seconds. I used duct tape to seal the shop vac hose to
the conduit to avoid pressure leaks.

Subject: Re: [TowerTalk] Another conduit question
I have seen some questions about having a broken line in a conduit and how
to run a new one.
I worked for a short time at a vacuum cleaner place, and one great way we
found to pull a line though PVC pipe was to tie a rag on the end of the line
and insert it into the end of the pipel Then go to the far end and put a
hefty vacuum cleaner on the pipe and suck the line with the rag tied to the
end through the pipe. Then you can tie that line to a bigger pull line and
pull it through. Works pretty slick.
If the run is too long, though, it won't work as there won't be enough
volume of air going through the pipe. 73 Tom W7WHY
