I'm am in the process of running my av cables into a plaster board faced breese block wall. All the channelling etc was going fine until I ran into a gas pipe right in the middle of my path. The pipe was untouched but now puts up a road block for my run. I intend to use trunking so that I can run new cables in the future. I have attached a pic to show my problem more clearly Can anyone offer a solution to this?
