I am wiring my home with Cat6
and I have my 1st floor wired thanks to tips used from users on this forum! Well now, I need to go between floors! I have found a location that is a straight shot up, but since I will not be able to see between the floors, is there EVER electrical wiring run between floors (or plumbing) that I could hit? And if so, how do I make sure to avoid this?
Also, I was going to add some Blue Carlon Conduit for ease of replacement in the future, however I am not sure how to handle this...The issue I see is that the inside of the tubing is 3/4 inch, and the whole tubing in itself is roughly 1 inch. Which would mean I would need to cut a 1 inch whole from the crawlspace to the 1st floor, then from the 1st floor to the 2nd floor, then the 2nd floor to the attic. Again, I have found a straight shot, but how do I ensure there is nothing electrical/plumbing or any other obstacle that would be disastrous to hit in the path?
EDIT
Sorry that my ? is not clear. I am fine with cutting the drywall from floor to cieling to ensure there is nothing behind it. My question is, how do I ensure that between 1st floor and 2nd floor where I drill up, there is no electrical wiring or water pipe(s) or anything else that could be hazardous to drill through? .g
