We noticed occasional water seepage on floor near one of the mounting bolts. I assumed it was a faulty wax seal, so, we removed the toilet bowl, and replaced the seal. We thought the matter was resolved, but, then we observed that especially when there is weight on the toilet, water gushes from this same bolt area on the floor when flushed. Again, it doesn’t do this every time it is flushed, so, I assume there is no stoppage in the drain, and even if so, why would it backup through the drain (and through the seal?) onto the floor rather than the bowl? Any advice is appreciated.
