It work fine for the first couple of tanks but now it won't stop leaking. I only use it two days a week when I do my long workouts. Last weekend I filled it up Friday night and when I picked it up Saturday morning half had spilled out onto the table. I used it anyway had maybe 5-6 drops, by Sunday it was nearly empty and I ran out before my 45 mile ride was over. I ended up putting it in my vape box until last night. Last night I took the top cap off and found the chimney loose so I tightened it down thinking that would fix the problem. I filled it up last night, took a few puffs to set the vacuum and had the same experience. What is going on here.
