[TowerTalk] Pulling wire

[hermans]

Terry,

In my opinion if you dont obstruct  both ends, wich isn't necessary when
its clear of the drop, then the circulating air will dry out the pipe
inside.
At this very moment with abt 20°c inside and near 5° c outside sure the
fog wont settle inside . That’s why Marc put the ends in a cabinet....
isn'it Marc. So no holes in the pipe underground, afraid you will suck
water trough the holes in a wet environment.

What are the thoughts pertaining to condensation in the pvc pipe.  Do
you
drill holes in the pvc pipe at the low points or just let the cables set
in
water?  Thanks
