Removing tree root clogging pipe - GIF

[Frank S]

That is crazy, I want to know how they broke it loose from the tree!! Roots are strong.

Since they are pulling it from the end of a pipe at the coupling, it would be safe to say the missing section of pipe was where the root made its way inside. They had already cut it from the tree and the part ov the root being pulled out was the length of the tendril that had grown inside the pipe. most of that clog was probably hair soap paper possibly garbage disposal material and fecal matter packed around the root.
