That senior installer told me to always leave a service loop behind the wall plate
He was right, I went back to fix a loose connection yesterday and that extra 6 inches of cable saved me from having to run a whole new line through the attic, has anyone else had that tip get them out of a jam?
Ha, is it really that dramatic though? I've had to rerun plenty of cable and six inches never made or broke the job for me. Usually just means pulling a little slack out of the bundle, not a whole attic expedition. Maybe your crawl space is way worse than mine, but I'd call that a pretty rare edge case.
