We had a bad wax ring on the toilet so we replaced that, then we decided to replace the toilet with a newer model. Now the toilet doesn't flush right--sometimes we have to flush it a couples of times for things to go down.
We thought it might be a clog so we had a plumber company clean the lines out there was nothing blocking it. They suggested that the vent stack might be clogged so we flushed it out with water and capped the vent pipe. However, the toilet is still acting up with bubbling and gurgling sounds and we can't figure out whats going on. Any suggestions?
