I installed a "pull rope, or messenger cable" when I installed the
conduit. No need for the exercise of blowing a cable through the pipe.
The rope is a bit over twice the conduit length. 4th photo from the

After over 30 years of being an electrician and dealing with countless buried pvc pipes
the reality is that sometimes the pipes are dry and sometimes they are full of
water...... Probably about 50/50. Plan on there being water in the pipes and also plan
on blowing or sucking the moisture out of them periodically. Greenlee makes an excellent
vacuum that is no doubt a bit pricey but a shop-vac may work also, never tried the
shop-vac. I bury all my pipes for the advantage of easy future repulling of cables. No
need to re-trench every time I want the latest and best coax or figure it's time to
retire the old cable or coax. It will also look much more professional than the
"Clothes Line" method. The disadvantage is that you will need a helper or two
to blow the string in the pipe and pull the cabling. If that is a worry then just use a
trencher so you can do the work yourself maybe. Whichever way you choose I know you will
enjoy the results..... Good luck Russ K5ZZ
