I have noticed that sitting on my toilet feels a little crooked, and today we have removed the toilet to inspect the flange. It’s an older flange with a metal ring and PVC insert which I imagine is the kind that is glued to the drain pipe inside. The metal looks pretty warped to me (ie im pretty sure that it’s lower around two of the screws and higher near the others, kinda like a very subtle roller coaster), which I suspect is why the toilet sat a little crooked but I’m not too sure as I don’t have experience with this.
I think it would be a good idea to replace it here but I have also seen these “repair kits” that can go over the top, like this one: https://www.homedepot.com/p/NEXT-by-Danco-HydroSeat-Toilet-Flange-Repair-10672X/204403879
I’d be all in on replacing it except it’s a little scary to have to cut the PVC insert while making sure I don’t cut the drain pipe as well, especially since I’m not too sure where one ends and the other begins, so I wanted to ask if anyone had advice on what might be the best route to take. I’m comfortable with cutting the old one out if I can be confident enough that it’s not a terrible idea :-)
