BS on it being a t shirt. How can you get a t shirt down a toilet ? And wouldn't it only cause that persons house to flood? And how then does it push sewer water back up in to 11 people's houses? Did they send someone down into the sewer drains and they found a t shirt? How can they prove that t- shirt was the one? Don't sewers have back flow preventers? And aren't the back flow preventers designed for this very reason? To prevent this horrible thing from happening? Don't sewers get drained ? More info is needed ! This " t-shirt" is not the answer. Magna water needs to answer for this.
