I'm at my wits end, trying to find where the toilet is leaking. I am not a plumber, but have replaced many toilets without any problems before now. Pulling a toilet off, unplugging something like a stuck toy, then replacing the toilet with a new was ring is pretty standard stuff and I have done it at least fifteen times without any issue; however, this time is different, because I can't seem to find where the water is coming from. After pulling the toilet, making sure that it is totally clear/unblocked, cleaning the base, where the new wax ring interfaces, then reinstalling it with a new wax ring, after a couple of flushes, water begins to appear on the floor around the base of the toilet. There is absolutely no water leaking from the supply line or the tank and running down the side of the toilet. The last time I went through the above-stated routine, after pulling the toilet off the floor then setting it aside, I had the toilet sitting on the floor, two feet away from the hole in the floor and the flange, when I noticed that water was slowly oozing out, appearing around the base, just as though it had been installed and had a broken wax ring or something similar. So, it now appears to me that the toilet, itself, must have a crack in it and is leaking. So my questions: Is there a way to check/find a crack in the porcelain of the toilet, itself? Has anyone ever experienced such a leak in the actual toilet bowl/goose neck before? I have never heard of such a thing, but, as stated, I'm not a plumber, so that doesn't mean anything. Doing a visual inspection, I can see no cracks anywhere, so it must be up higher in the 'gooseneck'/trap. Any way to test this? Any idea? Any help would be greatly appreciated.
