Hey DreamingButterfly81, you have some citrus juice in there? I made some lemonades [strawberry, peach, & blueberry] that were DELICIOUS, but they leaked out of EVERYTHING! I finally had to mix them with more PG and combine 'thicker' juice.
As far as the grommets or o-rings getting out of shape, I boil water and soak them in it [with the tank, clearo, whatever] and then let them dry. I have made a punch in the wrong place previously and it affected my grommet shape... after the hot water bath and drying it was fine!
