Broken sewer pipe in Caledonia, MN home

This is a potentially dangerous situation.  Old galvanized plumbing pipes rust from the inside out, leaving holes in your plumbing lines, allowing raw sewage and poisonous sewer gases to back up into your home.  In this case, the sewer line has rusted completely through.  A plumber should have been consulted long before the pipe got this bad.  Part of home ownership is keeping your home updated, for safety if nothing else.
