Is there any way of stopping a CE4 tank from leaking? I'm fairly new, less than a month, and have a couple CE4 tanks that have started leaking onto the battery. I've probably done something wrong when I refilled or cleaned (rinsed out with a syringe) them before switching eliquids. But, still, a buck is a buck and if I can fix them rather than use a new one I'd like to. Also like to know what may have happened so I don't do it again...
