So, I bought a hookah from a lounge in Jacksonville - Sahara. I'm trying to buy a vortex bowl, a new hose, and a replacement valve for a valve that's been stripped on my hookah. I'm a bit hesitant about buying offline and I feel stupid asking these questions - but I figured this was a good place to ask questions. Should I be worried about my hose and bowl not fitting? I've read about wet paper towels and stuff. I don't know. I need help.
