This is exactly what I am doing in Green Creek, NC at my mothers house.
I had about 30 min of time to run something from the well house to the
log house for ant feeds and etc.  The plumber had 3" PVC and had to make
one 90d bend and you guessed it, he only had one standard elbow. That's the
only mistake so far that was made.  Should be either two 45d or a sweeping
conduit elbow.  I did get 5 LMR400 coax plus one Wireman rotor cable and
one romex ac feed.  Also added one rope (actually only had some spare RG58)
in case have to pull another line.  Was a tight pull thru the elbow but
went ok and no signs of damage.

Hope this helps and keep up the good inputs here.   Read all and gain lots
of knowledge.   Tnx all.
