Wondering what jetter users recommend for "light jetting". What I mean for instance is something like Orangeburg. You can sometimes encounter it where it is not oblonged or damaged so it could have years of use left. But it's not uncommon to find long sections with jelled(?) obstruction in it. It's soft enough to move around pretty easily physically, but typical plumbing use will not.
So, is there a recommendation for "light jetting" that will move this but at the same time won't blow through Orangeburg?
(I already know to remove Orangeburg whenever possible.)
