Currently I have, courtesy of the last owner, 3 wires running to the "socket" behind my TV. It's a coax and 2 audio cables (image below), and they go to the fuse box/meter box in the hallway. . I'm not sure how they run, but at least: in the wall they go up, through the ceiling (probably some turns there), and then back down into said box. The yellow PVC tube they run trough is about 1.5cm in diameter (also see below).
Now I don't need an audio cable there at the moment, but I DO need network. I have a "wire pulling spring" (not sure that's the correct term). I figured my options are:
- Attach the spring to one or all wires, pull everything out, pull everything I need back with the spring
- Attach new wire to audio wires and pull the audio out and the network in with one action
- Attach the spring to the audio wire, pull the spring in and the audio out in one go, then pull the network in with the wire pulling spring.
Option 2 and 3 mean that if I do get stuck, I won't be in a worse situation: the coax is still there. On the other hand, I imagine failure is easier if you don't pull out all the wires.
My question is of course: is there a dead-give-away best method, or are there options/considerations I didn't account for that might provide a 4th way or at least pick a certain winner of these three?
(As an added bonus I wouldn't mind some help or links to the best way to attach springs/wires to other wires for these purposes, but that's kinda a seperate thing.)
