The Heart. The heart is the center of your hookah, where the Hose ports and purge valves come off of. If you look at the bottom, your hookah will have 2 holes (95% of the time) or 4 holes. If you have 2, one is directly for the hose port and the other specifically for the purge valve. If you have 4, all of them are for Hose port or purge use
