I am replacing a toilet in my parent's house (putting the same one
back in). I removed the toilet because it was leaking through to the
ceiling below. I had to pull out and replace six tiles, and I will be
going back tomorrow to reseat the toilet, having given the mortar a
few days to set.
When I took the toilet out, the plastic insert that comes with the wax
ring was crooked, and I assumed that was the reason for the leakage.
While I had the tile out, my father put a torpedo level on the top of
the drain and determined that it was not level. I don't know how bad
it is, because I hadn't really noticed. Based on the fact that I
hadn't noticed, I am assuming it is not too bad, though. The drain is
even with the subfloot, so there is the tile and mortar width between
the bottom of the toilet and the drain.
There's the background, here's the question: I was planning on simply
reseating the toilet with a new wax ring. Do I have to do anything to
account for a slightly off-level drain?

Unless the drain is really out of whack, you shouldn't have to do anything.
Make sure the toilet isn't sitting directly on (one edge of) the drain. There
should be some space for the wax ring. You can also get wax rings with a
plastic "funnel" sort of thing that goes over the toilet horn and inside the
drain. I prefer these, if there is space for them. ...not a plumber, though.

I see your concern, but as long as there is a space in there all should be
well. The only problem I've had is where the horn is actually sitting on the
plastic piece. As long as there is space for the wax, it shouldn't leak.
Also, make sure the toilet doesn't rock; shim as necessary. I have had to
resort to "gluing" the shims in place with silicone to keep it from moving
when the tile wasn't even.
Some run a bead of silicone around the toilet base but I've never seen the
need. If you do, leave a gap at the back to let any water out (so you can see
Just to be safe, see if you can run a hose, or pour a pitcher of water
down the drain and see if it still leaks. I don't think a wax ring
that had a shifted funnel could have caused the leak, but since you
have everything off, might as well test it now. The leak might be
from the elbow or lead bend if you have one.
If everything looks good, then it probably was the old wax ring. The
new wax rings with the funnel are made pretty good.
If the flange is fairly straight, and a little off level, it should
not be a problem.
I must disagree with the other posters to date.
The flange should be above the finished floor 1/4 to 3/8".
If the tile was added after the flange was installed you need to purchase a
flange washer/spacer. Lowes part number
item #: 253224 Model #: 43646
shown on this page is an example of one:
Then the wax ring will make up for any slight differences in the level of
the flange. Be sure to use the can't leak kind with the sleeve. You could
probably get away with use one regular wax ring and one with the sleeve but
why take the chance for $5

Sure. Mine was 3/4" (backer + tile) below the finished floor. An extender
(1/2") and normal wax ring was all that was needed. Yes, they make
extra-thick wax rings, too. They make a mess if you don't really need them,
