Probably a long overdue purchase! I've finally kicked off "Operation discretely network the house" and am aiming to run network cables next to my internal down pipes. So far so tricky!
I've got down one floor so far, loft to the bottom of the bathroom below. With the side off the bath I can get to the boxing round the pipe and keep things feeding down. Unfortunately someone has stuck some loft insulation in the gap at the living room level, I assume just to stop noise as it's an internal wall? So yeah, Amazon (sorry world, we've got prime for a month) to the rescue, cheap cable rods arriving tomorrow. Hopefully will be able to push them through and pull back some string to help with the run.
The final drop down to the study will be interesting - the pipe is actually the other side of the stairs in the kitchen so I'm going to have to tunnel under the stairs (bought an access hatch to cover my tracks) and hope I can hack my way through (and there isn't anything else blocking it!). My boroscope has been put to good use but sadly had been yet to find an easy option. Trying to avoid cables outside as we're three stories to no way I can do it nicely!
Though I'm actually away on Sunday for a week and busy tomorrow so won't actually make progress until who knows when, but we're underway (ish). I just need to hoover and put everything back together before the family get home
