I scrapped the wax ring years ago. I can jerk a toilet off the bolts and put it back in 15 minutes I use
the Fernco system
Wasn't the bowl to pipe joint that was the problem although those hold down bolts look pretty rough. The issue was the tank to bowl connection. When I went to untwist the wing nut on one it turned really easily and then fell out onto the floor. The other one needed a bit of a push after turning it a few times. No wonder we had a leak.
The valve assembly had also decided to start spraying water and or just not closing completely. So tank came off. Outside to wash with the house. Scrape dried rubber etc. from all the mounting holes. Then reassemble.
Shutoff valve from the wall was hard to completely close and even then dribbled a bit of water out the end of the flex hose. Solution to that was to turn off house water.
All back together, no leaks. Works fine. Have to think about rebuilding the tap on the wall.
The floor seal won't be done until we do a minor renovation to the bathroom. In maybe 42 years????
