I put ordinary cable in black 13mm PVC tube used for garden irrigation

though you could always claim it is a gardening expense.
It is VERY difficult to pull the cable through the tube if there are
bends in the run. Preferably lay the whole thing out straight on the
lawn or down the road. Use a vacuum cleaner to suck a length of cotton
or string through the tube, then use that to pull a fishing line or
weed-eater cord through.
and when you pull the final run of cable through, pull a string through
with it so that if the cable turns to custard or you want a second
cable you can use the string to pull another one through.
how about doubling up the string length.
once one end is tied up to the cable (with another person at other end suck it
back through so the sting is recycled back into the pipe and once 1st cable is
through you've got the string ready for another cable to be run (repeat
process for a nth cable).
Make sure that the ends of the tube are protected from the rain or the
whole run will fill up with water and you have wasted your time.
