Long time lurker, but figured I'd make an account to comment on the Okeanos which I received yesterday.
All the pieces feel very sturdy and it hits like a champ, BUT I'm getting an issue with water leaking from the central hole of the bottom of the bubbler. When I put some in (filling to bottom of the UP logo as Sleepin in CA recommended), it seems fine, but after a few minutes water slowly starts leaking out the bottom, and if I leave it alone it'll eventually drain the whole glass chamber of water in about 15 minutes. Any ideas what I might be doing wrong? I've tried tightening the central rod of the bubbler and making sure the rubber seals are secured, but I can't seem to plug the leak.
Some how your creating a siphon effect.
It will only pull the water down if there is a clog somewhere and as the oil sits back down into the bowl it pulls the water in with it, once this starts it can't stop until the pressure is equalized in both chambers.
