I would say no, cause I fill mine ALL the way up, even to the point where when I put the thread end back through the hole it pushes some juice out with it... Once fillup is complete, I grab a paper towel and blow out all the excess juice that managed to get inside the center tube. So my conclusion would be exactly the same as Grammie's 1) Did not blow out the juice after fill up or 2) You cut/punched you own cartos and you just went deep and punchured the Draw Tube, thus allowing the fed juice into it, causing syphoning each draw.
