Are branches allowed in network pipes?

Hello,

our electrician has combined the thinner pipes from sockets with only one Cat7 cable at some points on one floor using tape and then continued them in a thicker pipe. In addition, the pipes do not end in the basement but in a cable duct, which will still be covered with drywall. Our site manager thinks this is all fine, but I wonder how it will be possible to properly change cables later if you cannot access the pipes from the basement and the pipes are used multiple times, so that pushing cables from the socket side always works against the other cables in the pipe.
Do you have to accept this?

Regards
John

You definitely won't be able to swap cables there. Is it even planned or agreed that cables should be replaceable later?

No later replacement is possible during execution. This is due to the radii alone.

What has been agreed? Cable interchangeable or only cable in protective conduit?

Hello,

During the renovation, we also laid pipes to be able to replace cables later. Please don't forget. You don't have to push the new cable but can pull it. You already have a cable in the wall/socket where you can later attach the new cable. When you then pull out the old cable, you pull in the new cable. That should work as long as the diameters fit.

Regards

Thank you very much for the input. Changeability was only agreed upon orally, but it is not stated in the contract. Are such "switches" common, or does one usually only lay a continuous pipe from the outlet to the patch panel?
