I recently purchased 2 tank systems, and really like them. I am having trouble with both of them leaking juice out of the breather holed on the attys. They seem to be ok at first, but for some unknown reason they will begin leaking out the holes and down the outside of the unit. They usually leak out all of the juice that is in the tank. I have tried different carts, as well as 4 different attys. I have made certain that they click into place, and are flush with the atty also that the top on the refillable carts is securely in place, but they continue to leak. Anyone else having this problem. Or a solution to it?
