Hi all

 

Currently planning to run 2 lengths of cat5e between upstairs and downstairs whilst redecorating to remove the cable under the carpet we have currently.

 

Ive spied a route for the lengths of cable to run, however theres a old copper pipe up to the loft I can use which ends exactly where I need it to be.

 

Is there any adverse effects of running 2 lengths of cat5e inside a copper pipe?  FIrst guess would be interference but not sure how it would affect it.

 

Cheers

As far as I know, you shouldn't run into any problems with interference, unless there's cables exposed or it's run very close to an electrical source. Most of your interference is really only going to get caused by radio frequencies, but if those copper pipes are carrying a charge that could do it. You could always run STP (Shielded Twisted Pair) if you're really worried about interference.

Good discussion about it here. Stick with cat5e vs 6 in the thread.

The only consideration I would have, is if your copper piping is also used for grounding within the building. You could have some voltage leakage which would not be good i.e. interference as you mention. If you have cut it off and there is no water or other liquids in the pipe and it's isolated you should be fine and consider your copper pipe an Ethernet cable conduit. Before you pull the Cat5e through the copper pipe. You might also want to run a pull cleaner (duct brush) through it and see if there is any corrosion. If there is corrosion present, it could could eventually migrate to the jacketing of the Cat5e and eat through your new installation.

Thats not too bad then.  I know its definitely got nothing in as vertical pipe up the chimnea breast and cut both sides.  Grounding im not sure but cant imagine it is due to the location of it.
