My toilet started to leak water into the bowl. I've heard this before I went to Lowe's and they didn't have the part. I had to order it on line. I bought 2 rubber sealers, I installed one and it worked until the toilet flushed and then it started leaking again. There is a groove, the rubber sealer has to go around, but for some reason when it flushes, it must move. Do I have to put sone kind of sealant around the groove?
