Actually filled tank and toilet with water above the offending seal and water leaked out. Water tends to need a larger opening then air to leak. I did the fill carefully and just short of the toilet bowl rim. There was no leakage at the floor seal, only when I got to the top. rotating shaft seal. Toilet was under warranty and was replaced by manufacturer after explaining test procedure above.
Mine was a different model toilet and the shaft seal was not a replaceable component per manufacturer.
Thanks for responding back. Ah, now wasn't that ingenious! I assumed it was a "sniff test" and I had no idea how that would work!
