Neighbors had a plumber come by to snake the shower. One of the old pipes broke and leaked over and through the walls causing thousands of dollars of damage. He blames it on old bad pipes, regardless, I am curious if someone can explain how a snake can burst open 2" steel pipes? I have considered buying my own snake to work simple blocks but now I am hesitant. If I need to snake my drain what to be aware of to avoid this happening to me?
