This can be huge. Just tonight when I started my first session it wasn't smoking right. The first time I purged the rig I noticed smoke pouring out around the hose port. I reseated the hose and everything was fine after that. Also make sure you purge valve is seating properly. When I got my first hookah, I discovered a burr around the valve seat. The ball bearing wasn't sealing. Removing the burr fixed it right up!
