Good afternoon all, Decided to drill through from the front room to our dining room, to feed speaker cables through for multi-room sound. Its a typical new build - well, 4 years old - and I want to make sure i'm not going to hit anything I should whilst drilling through. Ideally I will be going through just above the skirting board, near the outer corner of the room, so not far from an external wall. I did read that most of the cables etc typically run quite high up from the ground, but I have no idea about plumbing etc, and where pipes etc could be routed. Also, what sort of distance am I looking at between both walls? In other words, how far roughly am I going to be drilling through? I would imagine i'm going to need a pretty long drill bit ! Oh, another thing. I am going to need a few metres of trunking to keep things tidy, any hints on where to get this from? Thanks for any help.
