Just realized I was wrong about those old apartment building conduits

Tbh, I got stuck for almost four hours yesterday trying to fish a line through a conduit in a 1960s building downtown. Ngl, I thought it was just a simple pull, but the inside was full of old, crumbly insulation that kept snagging. What's your go-to trick for clearing out a totally clogged pipe like that?

That crumbly old insulation is the worst, right? Honestly, a shop vac alone won't always get it. Have you tried a foam drain cleaner first to loosen it up, then flush it with a pressure washer hose? The foam breaks down the gunk so the water can push it out.

Ugh, that sounds like a nightmare. Henrys60 has a solid point about using foam first to break it up.
