Just had something weird start happening with one of my Lemos. When I flip it over to fill it, it starts leaking juice out of the top cap. I completely disassembled it and the clear tank o-ring is in place and looks good. As does the o-ring on the top of the chimney. It just started doing this recently. The juice has to be getting around the chimney stem somehow. Just can't figure out where. Performs just fine. Anyone have this happen???
