Q.Do A Lot Of Hard Work To Remove A Root Or Cut And Bury?
Moved in here a few months ago and started to get a very bad weed out of the garden that spreads like wildfire. I came across the root in the picture that was seemingly going under the house as well. I think the root is related to the weeds but it’s quite big and goes deep and now I have gotten to some kind of pipe. Should I just cut the root as low as I can or should I remove it properly/get it properly removed? Thanks!

Coming across a pipe is never good. I cannot speak for your local government's laws, but ours would require a permit to mess with any pipes underground. I would seek help from an official from your agricultural department.
Removing the root will be the solution, however, damaging the pipe may break laws or worse.
