My toilet flushed very slow, it would not go down, just swirled around the bowl. I poured some drain cleaner in and let it set for 24 hours and flushed then it seemed to flush fine for about a week. I decided it needed to be snaked at the main drain under the house so I crawled under and saw a bid drain about 4" in diameter with a bolt on the side of it. I tried to loosen the bolt but instead it broke off. How can I fix my problem. With the bolt broke it flushed great, but leaked into the basement.
