: I installed a toilet in a second story of an apartment complex, new wax ring and bolts, with no cauling around toilet, and the floor was new vct tile on softcrete... they say that the toilet leaked downstairs even though no water was visable on the floor... is this possible... i think it is a leak in the pipe as i think it would have atleast been visiable on the floor... can someone help? lol thanks.
It is possible that the toilet seal is defective and the water would only show up in the ceiling below.
I would lift the newly installed toilet and re-set it again. There could be some splashing going on under the toilet causing the leak.
Good Luck & Happy Holidays. e-plumber
