[TowerTalk] Putting a pull rope in conduit.

[Thomas Miller]

Greenlee sells a device(vacuum) to pull in a string in conduit.  Works just
really nice(have one at work).  I suspect that a wet/dry vac would work fine
also.  I have used both methods and they both have their place.  Be very
careful with the CO2(high pressure) that you know where the end is and
nobody is standing near it or in line.  I have seen water shoot up in the
air 30 feet.  Not nice either rusty nasty water.  Also rocks and other
foreign objects can come out like a gun.  I have heard of red plastic wire
nuts killing rats at 100 feet.
