Okay, I have an evod tank, and all was working perfectly fine until I couldn't unscrew it. Now, I can't fill it with juice. I've honestly tried every single thing I could to open it, such as running in under hot and cold water, having all my friends try, and I even used a pair of heavy duty pliers. I just want to know if anybody else has/had this problem, why it's happening, and how I could possibly fix it.
