Camera line thru toilet and pull and reset toilet. Camera the line 25ft to ensure nothing else could be blocking the line, when toilet was pulled noticed whom ever performed remodel used 3 wax rings with horns and one of the horns was down in the line near flange causing it to collect the toilet paper around it and make the toilet back up, once removed and reinstalled with new wax ring with horn began sealing around base and testing for leaks and functionality, everything is working as it should.
