Okay, so I was reassured on Toiletology.com that replacing the toilet and new wax ring over the flange/drain needs two people. My buddy held the toilet, I got down on the floor to eyeball how close the "hole" was to the wax ring/flange/drain. But then we both had to make sure the bolt holes in the porcelain accommodated the bolts, and unless you're cross-eyed or have a third eye in the middle of your forehead, you can't have your eyes on the bolts *and* on the drain/ring at the same time.
So I asked two handyman/contractor friends if you can EVER be sure you go the wax ring in exactly the right place, and they said No. They said just check and see if the toilet leaks.
You don't have to be a rocket scientist to see that the toilet might not leak at all but just *seep.* The seeping is ten times worse than leaking, because it'll lead to long-term rot.
Now I'm afraid to use the terlet.
