Toilet rocks when you sit on it?
 
I have a toilet set on tile. When you sit on it it moves forward a tad,
when you get off it rocks back to its resting posistion. I also notice
when it sees a lot of activity, a small amount of water comes out of
the front section where the base meets the tile.I have checked the nuts
and they are tight. I assume the tile is not level and this is the
problem? Any ideas on how to fix this? Thanks.

1. Set it in a mortar bed

2. Use wedges. #1 is better.

Install a new wax ring. In one case of mine I had to double the wax
ring and add two vinyl wedges to stop the "rocking" and get a good
seal.

The toilet should be supported by a ring of plaster of Paris under it.
So, insert some wedges and get the position where you want it. Mix up
the plaster and pack it under the thrown. It will become rock hard
shortly. Note the wax ring has nothing to do with support -- it simply
seals so sewer gas doesn't escape.

If you have a wood subfloor, you should treat the water leak with great
urgency. I'd wager that a little bit of water is leaking out with each flush
(after a 'lot of activity' enough leaked water has built up to leak out from
under the toilet). Since you have tile, you will most likely find a rough
cutout around the flange (the toilet's drain hole in the floor) where some
subfloor is exposed, which will inevitably suffer from water damage.

Tile sometimes causes sealing problems because of it's thickness and
standard wax rings aren't always enough to bridge the gap between the flange
and the toilet base. Use an extra thick ring, or in an extreme case (thick
tile like travertine on top of 1/2" concrete backerboard on top of wood
subfloor) you may have to stack rings.

Gads!

Water comes out?

Change your bees wax ring. Those rings are supposed to last 10 years,
but I'd put it on your maintenance schedule for review every 5 years or
so.

Leakage is gross and can result in dry rot.

That's the first time in my life I've ever heard anyone say that a wax
ring has an expected lifetime that short when installed under a toilet
that's properly seated.

What kind of failure mode occurs?

Can you offer a cite, perhaps from a wax ring supplier, which states that?

First, the wax ring is shot and needs to be replaced and any water
damage evaluated.

I heard a pro plumber recommend using pennies to shim toilets on uneven
tile floors (uneven tile, not uneven floor, which is a bigger problem).

Ring should not fail if properly seated. Water flowing down is not under
pressure.

likely a broken cracked flange or bolt:(

FIX IMMEDIATELY!

My mom didnt and had to replace entire bathroom floor including all new
tile. the water leak gets into the plywood delaminates and rots floor.
can cost thousands to fix if let go.

pull toilet, new wax ring check bolts and flange, repair floor if
needed.

YOU NEED TO FIX THIS IMMEDIATELY!

have to pull it asap. Thanks for your help.

Well one thing you can do is ask chicks to come over to your place. Tell
them your toilet ROCKS! When you say it, hold your hand up with the
forefinger and pinky sticking up like the devil's horns sign. Chicks will
dig it.

1. Set it in a mortar bed

I would never do that. What do you do when you have to pull the toilet for
some reason (repair, reflooring, etc)?

A bead of caulk around the whole underside of the toilet should be plenty to
keep it from rocking (once you replace the wax ring, as everyone else
indicated). I like to leave a gap at the back so that if there is a leak
in the future, you'll have some indication. If the floor is so unlevel that
caulk won't make up the gap, then I'd seriously be cursing whoever laid the
floor...

Add to that, forcing a bead of silastic or vinyl caulk between the perimeter
of the base and the tile floor.

1. Remove bolt caps
2. Remove bolts
3. Lift up toilet
4. Knock off any mortar. Easiest if one has thoughtfully applied a
parting coat of whatever. Ditto on floor.

"analogous", A N A L

Fixing a rocking toilet, in my case involved two wax rings stacked and
shims to get it to stop rocking and get it to seal correctly.. That is
what I posted. Every rocking toilet will/may not be repaired the same.

I like you better as Joe Dirt with the "bring the chicks over"

called on it since the OP had a leak. Now it is relevant, but not a

I will state this as I have befo a double wax ring and wedges fixed
