Yes, it does sound like they both tied into the same drainage line. It used to be common practice to use tile lines for your septic tank's leaching field around here and some just did not bother with the septic tanks when hooking up drains. Whoops!I'm assuming I saw the same article, not too many with basements flooded by a butcher.
I don't think it's on a sewer, the mainline to the septic blew out saturating the ground area with everything from the floor drain. It's gotta find a place to go and a basement is just a whole in the ground. If they got all that blood in there wouldn't the basement routinely flood anyways? Not a plumber, I just know shit rolls downhill and paydays on Friday, don't bite your nails. Haha
What a nightmare, the butcher basically told them too bad, fix it yourself. Hopefully he gets shut down over it, treating your neighbor like that is uncalled for.
Years ago my parents refinanced their house and the guy inspecting the house poured dye into the toilet and flushed it. They were making sure we weren't hooked into a drainage line (if we were that would have to be fixed prior to the loan) it sucked using the neighbor's toilet and showering under a garden hose for a week.
