Hi there. Got myself a K4 with Cleito. Worked fine but now it's leaking like a waterfall. I have read posts about leaking on this forum and have followed all the advices (keeping the airvent closed during filling up, priming the coil, etc.. There is no damage on the glass or the rubber joints. Every different solutions I have tried, and the bastard still leak like crazy. The last time I filled it (after replacing the coil with a new one, tied up all neat and good) and it was worst than ever, the entire tank emptied itself through the vents as soon as I opened them. Pouring like rain. Any advice?
