Toilet Seal
Thetford toilet porceline bowl, foot flush
For the last few camping trips, we have noticed a little water on the floor around the toilet. I have sat on the floor and watched water run through the toilet for 30 mins and I saw no water leaking anywhere; lines, connections, bottom of toilet at the floor. But over the course of a few days, the water shows back up on the floor around the bottom. Just pulled the toilet and saw the seal is grayish black foam rubber. Doesn't it need more than that? Maybe some silicon caulk at least? I don't know if the water is coming from this or not. Other than the screw on water line, all the other connections are the spring clamps. Maybe a flush valve problem? May have to have more observation! Or some info from the Herkbrary!

My friend, I think you have to look for another source for the leak. Unless the seal is damaged, I don't think it is the source of your leak. I would look at the water inlet connection, flush valve or some other source. The gasket only keeps water from seeping from the stool when you flush. It has virtually no pressure on it and is only a momentary use item.

What he said. I had to replace the water valve in our toilet this summer and had the whole thing apart. I would say the only place water can leak from is the inlet fittings or valve and possibly the vacum breaker above the water inlet. That seal to the floor should not leak if the toilet is securly fastened to the flange. We have the same toilet as you BTW.

Is the toilet fairly easy to take apart? Guess it has fittings inside that could be tightened. Are there seals and o-rings to replace? I'd say the toilet hasn't been used that much.

It may have a pc of debris in the flush valve or the inlet fitting. Just shut the water off, city water and pump, flush to relieve pressure and remove the toilet. Stuff a plastic bag with a towel in it in the black hole and start examination of the fittings. The flush valve will have to be removed from the toilet. You can buy replacement flush valves at your rv dealer or Camping World.

The Herkbrary input. I agree it is not the lower seal.
Look for a leaker at the flush valve.

After pulling the toilet, taking it apart, looking, looking, looking, reinstalling, uninstalling because I had flipped the seal that goes between the bowl and the base(wouldn't hold water), taking apart again, reflipping the seal, putting back together, reinstalling, connecting the water, and.....that dreaded pop!
I hope the plumbing supply store is open tomorrow. 
Still don't know where it was leaking, but I know where it is now!
Damn plastic!
