If I buy the lowest price Drano does that somehow mean that my drain wo n't be clogged ? Apparently yes . I poured the whole thing down the drain and let it work for an hour like the bottle told me to do . Then I flushed it with hot tap water .
According to the above context, answer the following question.
How many bottles of Drano did I have to use to unclog my drain ?


None of the above choices .
