Tried to remove my Mom's toilet to check the wax ring, etc as it was leaking at the floor rear with every flush. I did a couple in my time but this one wouldn't budge. Learned the person who installed it set it in Plaster of Paris. Tried some medium pushes, pulls, shocks with the palm of my hand, and using a mini carbide hand saw around the perimeter but that went nowhere slowly. Someone told me a good swift kick usually works for him but I'm reluctant as it's a medium priced one piece unit. Any suggestions? How much of a shock can a toilet take?
