Plumbing Question, does this seem strange to you?

First of all if the toilet is upstairs, the line is not plugged, just the toilet because everything downstairs would be flooded out first.

It may be the jets - under the rim are plugged in which case you can use a mirror & flathead screw driver to unplug them.

It could also be that your water level is low - in the tank the water should be about 1/4 inch from the top of the overlfow tube in the middle.

Then too, it could be that the throat of the toilet either has something in it (pen, q-tip etc) or that the toilet is just old & the calcium build up is starting to really effect it. It might not be such a bad idea to change it if you own the home.

Second is that water will seek its own level - most likely there is a breach in the wax seal & when flushed the water will run down the pipe & follow it till it drops (that's about the best I can explain it because water does not always drip straight down).

My educated guess, without being able to test it is that changing out the toilet would solve all the problems.

Here is an important rule of thumb - if you pull the toilet & replace it use a wax ring without a flange if the pipe is jagged (you could even use 2 if necessary) - use a wax ring with a flange if the pipe is smooth.

Your toilet is not overflowing but the pipes connecting the toilet to the drain, above the ceiling are.

When new and clean, the pipes are larger than the narrowest part of the toilet. With time, stuff accumulates inside the pipes, reducing the effective cross-sectional area, making them clog more easily.

First thing to fix is the clog. Call in the experts to clean out the pipes; it's not that expensive. To do the job right, they should remove the toilet and snake out the pipes with a cutter head. You can rent the equipment from a home centre or tool rental, but if you are not experienced, you might not have the right head and could miss other signs of trouble. With the toilet removed, you’ll see if the leak came from the old wax seal. New wax seals should always be used whenever a toilet is removed—never re-use the old wax seal, they will leak.

If the source of the leak is not obvious, you’ll need to take the ceiling apart to find it—I guess you’ll need to fix your ceiling anyway.

The toilet probably has an overflow which is why it's not over flowing (a small hole at the very top inside the bowl) . As far as the leaking, it's probably leaking where the toilet meets the floor (there should be some sort of wax ring/gasket). Hopefully nothing damaged the drainage pipe so every time you flush, it leaks. Bottom line, take the toilet off and go buy a new one. The whole project takes an hour and it's really easy. Just tell the Home Depot guy what you are doing. And remember, don't over tighten any bolts that secure a toilet!!

The leak is coming from somewhere, so it must be from the toilet, maybe at the flange seal. I'd get someone to remove the toilet for 2 reasons: to make sure your wax seal isn't leaking and to have a better chance to unclog it. You can make sure the drain pipe isn't clogged, or unclog the toilet's internal trap if this is where the clog is.

The outlet pipe from the toilet may run under the bathroom floor for a distance and may have been disturbed / settled etc... the blockage may be due to this and / or the escape of water may be due to the blockage causing a joint to leak ......need to trace soil waste pipe from back of pan to locate the leak. To clear the blockage first ....flush and immediately use a mop to plunge the toilet - like a pistion back and forth into bottom of pan - it should move it after a few attempts - then use buckets of water to flush through quickly to move the roll of paper on

My guess is that the drain is leaking where the pipes join. It will need to be opened up for sure. The slow drain, it is plugged, withoug a doubt. If you are not a plumber get one or become one. It won't get better and by the way, that stuff leaking is sewerage!

check out your roof vent,have you had a new roof?it is leaking around the wax seal,does the lower floor drains back up?the wax seal is not the problem.

Your waste pipe might desire to have some variety of seize it particularly is comprehensive with water whilst your no longer utilising the bathe. The seize keeps the sewer gases from coming lower back up the drain. verify and confirm you have that seize, and that it holds the water.

You need a new wax seal.
