Bought a Toto Drake toilet after all the good advice on this excellent site. Water surface fills to approx. 8 x 10 inches but then loses about 30 fl. ounces or so of water within a just a couple of minutes after filling to a final surface of approx 6 x 9. Was thinking poor vent or blocked vent was causing a vacuum. But I filled the Toto by hand hours later with no other water usage or drainage going on in the rest of the house. The Toto still drained to the 6 x 9 surface within a couple of minutes. Would poor venting cause a vacuum that would cause this to happen hours after flushing? Also thought about the rare possibility of some crack in the toilet. Would I always see some sort of water evidence on the floor of the bathroom or on the ceiling of the room beneath? Is it possible some internal crack might just drain without any evidence? Sorry to be so wordy but I thought I should give as complete a picture as possible. Thanks for any advise to this puzzle.
