Howdy,
I have a underground conduit that runs about 340'. Right now, it holds two wires (a networking cable, and a phone cable) but there is no pull cord.
I want to pull a fiber optic cable...
I have been told that with the proper setup one can use a shop vac to pull a thread through the conduit (the thread, in turn, pulling a cord etc.) It was suggested to me that a ping pong ball attached to the thread would do the deed, but there is not sufficient space for the ball to enter the conduit.
(I should add that I could use the network cable as the pull cord, but I would strongly prefer leaving it in place until I have its fiber replacement working.)
Anybody out there know how to approach this hassle?
Thanks for any help,
