Yesterday, attempting to add a single run of CAT 3 to an underground conduit (4" wide, over 250 ft as it turned out) with a few existing cables--but with lots of room left--the CAT 3 cable I was adding snapped just about 15' before I got it out. The old pull string was OK...it was my cable that broke. No matter, I guess. Broken is broken. I probably didn't lube it very well. My 240' fishtape was too short, so I couldn't go on. (A phone guy friend said he uses shampoo poured down the conduit and it works great...better than Yellow 77). Anyhow, has anyone successfully used one of those "rodders" that are fiberglass fishtapes on a reel, like 400ft long, especially where there's existing cable? My friend warned that, even if I had one, I'd be taking a chance damaging the existing lines. How about equipment that sucks a dart through the conduit? What's worth trying when the conduit is this long and partly occupied?

When I know a pull is going to be a bad one I'll pull in a new string with the old string, lubing the new string untill
I've got lube all along the path of the string. Then I tie
on the the new Jkts or Cable. This way the path, however twisted around the existing wire is pre-lubed. Makes the pull a lot easier and helps to prevent the string from burning any of the existing wire.
