Cable penetration wall?

[memike]

Hello.

I am about to make a cable pass-through in the outer/inner wall to install a "first" telephone jack.

Should I buy a special kit, or is it enough to drill a slightly downward-sloping hole and fill it with foam afterwards?

Any tips are good tips.

The simplest solution is enough. If it's underground, then you might want to look into how it's usually done. There's always a risk that you might get water through the cable.

Is this a guess or a professional answer

The cable should enter about 1m above ground, so there shouldn't be any issues. I first considered drilling large enough to push in an 8mm VP pipe and then threading the cable through while filling the VP pipe with foam sealant.

There is no major magic or requirement of professionalism to drill a hole in a wall. A VP pipe is a plus as it facilitates the replacement of the cable. It may also be worth considering the protection of the cable on the facade, not only mechanical protection but also against sabotage.

Doesn't the telephone operator fix up to the first jack?

If you're worried, fill the hole with epoxy. It's completely waterproof. That is, drill, thread the cable through, fill with epoxy = better than new.

Is it really good to use epoxy or foam sealant if you want to pull out the cable?

 

[Nerre]

Probably not. The question is somewhat about what the point would be of completely filling the hole? If you only seal one end (silicone or latex sealant?), there will be no airflow through the pipe, and the stagnant air is unlikely to be a significant conductor of heat, so it wouldn't affect the insulation.

Is it really good with epoxy or foam sealant if you want to pull out the cable?

Hardly... I would settle for a "wad" of insulation (like Gullfiber) at the end of the pipe. If you're really worried about water starting to run slightly upward in the pipe, then maybe a cm of silicone plug at the very outer end. At least with a little good will, it can be carved away if you need to change the cable.

Filling the pipe with foam sealant or epoxy feels a bit like you are ruining the usefulness of having a pipe.
