I have 6 Tigon tanks maybe 1 - 2 months old by now, and all of them have started leaking. I can't figure out exactly what's happening, but most are leaking from the bottom of the "sliding" cap as I draw. Other times, liquid is coming from the bottom air port (the one that can be adjusted).
I don't think it's any of the gaskets/seals as those aren't really near those areas (maybe the o-ring of the coil itself for the bottom leak). Any clue on why this is happening? Even with a brand new coil, it will leak at either spot. Even just sitting there standing straight up on a desk or something, completely off and not using it, there will suddenly be liquid all over the tank. It could be 1/2 full, completely full, or less than 1/2 full. It's not tilting to make liquid come up over the top of the coil area.
