I have a maphisto dripper and i was wondering if i can just take the tip off to put juice in or if i have to take the cap off? Every time i take the cap off its hard to get back on because of the gasket it came with. I tried a smaller gasket but it broke. I dont know if its meant to be taken off every time i want to drip or not. I do know its a pain in the ... to put it back on
