Be interested to find out how people get it through ducting in buildings without pulling.
In my time have pulled long runs from out under stacks of muddy power and audio cables and it has survived and working at gigabit fine.
Can't argue with experience - trumps theory every time. However, I well remember reading an article by a highly experienced network specialist, where amongst other woes he records
"Anyway, in the end it wasnít my dodgy carpal tunnels that caused the biggest problem, it was the fact that those helpful electricians had pulled through a lot of the cable runs, and as a result about four of the 16 cables had at least one of their conductors snapped inside the cable sheath. CAT-5 cable for wall trunking is solid-cored and therefore not all that flexible or strong. Itís meant to be laid, not drawn."

Two contrasting experiences!
I would give the wiring a good old test before panicking too much though.
That seems the best course to me.
Just use the possibility that it might need replacing in near future as a bargaining chip
Thanks for giving me some hope
