Toilet is at least 25 years old. One of the good ones, with big tank and lots of flushing power. Sits on a concrete slab floor, vinyl tile. Never had a problem with it beyond a few minor leaks, replacing the float & fill mechanism, etc. Rarely clogged.
So, the other day, I accidentally bumped against it and it MOVED a good half inch on the floor.
I checked the flange bolts and they are loose as can be. I can actually pick the bowl up about 1/4 inch off the floor and set it back down. I haven't taken the bolt covers off yet, so I don't know exactly what the problem might be.
Going to HD on my lunch hour to get a new wax ring and flange kit. Will fix this weekend. But I'm curious about how something that has been so secure for so long can suddenly start to move around like this.
