The next video in the home networking series! Last time I discussed what tools you need to run your network cable through your wall or conduit, this time I show you how to do the work!

good tip 🙂

Ben Arndt says:

Great video. But don’t try the vacuum-method with the standard conduit in germany. It makes a terrible high pitch sound….

Guido Mennen says:


Why didn’t you trim the excess conduit that terminates in your wall boxes prior to pulling the cables? That stuff is a b*tch to shorten with the cables already in them, especially in tight places like wall boxes.

Sokrates297 says:

Use more lube!
Just squirt a good amount of lube into the pipes before threading the cables.
the cable will feed the lube forwards and will also lubricate the cable as it gets further in.

Pancho says:

Τhe best method to deal with long distance cabling installation or bendind sections is to install crossing boxes so you can work through them for once and then keep on to the 2nd section till the final end .The vacum machine and string idea is so troublesome and time wasting !

Nice to see you doing all this in your new house 🙂 Imagine doing that with thick ethernet 😀

Guust says:

Another nice video! A few tips: 1) strip the cable a little bit more so that after connecting to the pulling wire the pairs through the eye of the pulling wire do not touch the (red) outside of the cable. This makes the connection thinner. 2) Tape the second cable a litte bit (about 1 feet / 30 cm) further from the pulling wire. These 2 tips will makes it easier to pull the cable, because the point of the cables easier bends through corners. If the point between pulling wire and the cables is to stiff you will notice this at the first corner you reach.

Why dont use prepered pipes?? If I gonna to build a gonna use pipe like this http://gigamedia.se/datanat-koppar/datakabel-koppar/fordragen-i-slang/gigamedia-flexror-16-1xkat7-utp/

This is a video on running cable through existing conduit. Misleading title.

Orian Leitersdorf says:


Do you think it’s possible to pass 3 or even 4 cat 7 cables in a 20mm pipe (7.87 inches)? If not then I think I might need to get cat 6…

Nice video! Great to use in my new build house soon! One tip; look after the volume of the sound when you show your logo. I had to louden my sound when you speak in the beginning, but the sound during the logo is much louder…. Lowering the sound is ofcourse easy, but you’ll need to higher it again once you start talking. Keep up the good work with your videos!

Orian Leitersdorf says:

Is 3/4 inch pipe the inner diameter or the outer diameter?

Soepkip87 says:

Yes, pulling wire is more pushing wire indeed. Always keep tension.
I do it often times with electric cable and thanks to the thicker copper and a good connection to the pulling wire you’ll be able to pull harder in those nasty bends.

Another tip would be that if you still have access to the pipes where (several) bends are placed you can often times pull them open, push/pull the wire through the straight first, take some extra wire and then do the bit with the bends. You’ll have these situations especially in ceilings etc.

Oh, and when you actually place the pipe/buy the pipe you’ll be threading through: GET THE ONES WITH THE RED INSIDE! I know they are a bit more expensive but expecially on the longer lenghts you’ll save yourself alot of trouble. Why? Well, this red stuff is a sort of lubricant!
