Ok, folks!! We recently purchased a new home that seemed to have a serious clog in the drains. Our tub took an hour to drain after a bath, so we decided to try drano. It seemed to work and we were very excited. The tub drain was working. The next day, I gave my son a bath, and when I was draining the tub, I also flushed the toilet. This caused a huge backup, and water started flowing into the basement. Our basement is finished the only issue we noticed when moving in was that there was a weird 2 inch hole in the ceiling. This is where the water was coming out of. So this was obviously an issue in the past. Anyhow..We used a snake yesterday to unclog the drain. We had to take the toilet apart and run the snake through there to unclog it. It seemed to work. Last night, we all took showers and did have any problems. Tonight, I gave my son a bath, and when I began draining the tub, I instantly heard it flowing into the basement. It is literally flowing like a waterfall in the same place as the 2 inch hole. We have removed about 3 feet of drywall, but Im not sure where the water is coming from, or why!! HELPPPP!!!
