Re: newb Q
I don't know what kind of hookah you have but Mya Saray make auto sealing valves that you can buy for their hookahs. I use them on my Mya Colossus and they work very well, there is a little ball bearing that is in the hose port so even when you are smoking with 2,3 or 4 people nobody has to worry about putting their finger on their mouthpiece if they aren't smoking. Just make sure that they will fit on your hookah. Check out hookah-shisha.com i know they sell them. Also it barely effects your drag so don't worry. I usually am using a nammor hose and there is a very slight difference but not much.
