Re: hookahs cant purge!
The ones here use bulk coals. They always put three no matter the size and all of the hookahs are common chamber hookahs. Remove a coal and blow that is all you can do. At least the purge valves relieve some of the pressure so we have never had the water in the bowl problem but we found that we can clear it out with quick short bursts. It pisses them off but really if they would just give us tongs and allow us to regulate a little then it wouldn't be as much of a problem. If we are feeling lazy and just really in the mood for some Nakhla DA and some great food we will go to Lizzy's where we get total control after it is set up and everything.
