the miles of conduit i installed and pulled wire into
i have found it better to remove the old wire pull it back in with
the new wire
unless you use a new conduit
put 2 runs of conduit in ware you need one now
2 in conduit mite help with a small fill
like wire that would fit in a 1/2 in. in the two inch
they make liners to help you add more wire later its
used in underground ducks
its polyethylene i think and you pull them all in at one time with a
light pull string in it to pull rape in with
