hookah hippie Posted July 27, 2008 Share Posted July 27, 2008 is there a ball bearing on the inside of it??what happens is a ball bearing should sit in the hole and then you blow threw the hose and it moves the ball bearing and the stale smoke leaves the base If there is no ball bearing you can put a 12mm bb in it Link to comment Share on other sites More sharing options...
coplinb Posted July 27, 2008 Author Share Posted July 27, 2008 no i dont think there is a bearing in it, i cant hear one rattling around, just a hole with a knob you can tighten or take completly out. Link to comment Share on other sites More sharing options...
hookah hippie Posted July 27, 2008 Share Posted July 27, 2008 then get yourself a ball bearing or a bb in the meantime you can block the hole with tin foil but then you can't clear the chamber Link to comment Share on other sites More sharing options...

ahhhdam Posted July 27, 2008 Share Posted July 27, 2008 The vent knob that you call it is really called a purge valve. And as hippie explained it is to purge (hence the name) the stale air in the base. Just put a bb in there and purge away. Good luck Link to comment Share on other sites More sharing options...
Codename067 Posted July 28, 2008 Share Posted July 28, 2008 ff that does not work and you simply want to give up, seal that up with some clay. Link to comment Share on other sites More sharing options...
derogatory Posted July 28, 2008 Share Posted July 28, 2008 I've seen hookahs like this before. It is a purge valve but you cannot put a BB in there. Just keep it completely shut when smoking and unscrew it a ways to purge. Or just leave it shut all of the time and clean your hoses regularily.

TexasHookah Posted July 28, 2008 Share Posted July 28, 2008 The purge valve or air valve definitely needs a ball bearing to close out the port when you inhale and to open up to release stale or harsh smoke when you blow in. Link to comment Share on other sites More sharing options...
TizaNabi Posted July 28, 2008 Share Posted July 28, 2008 Another thing about some pumpkins and minis is that there are those whose shaft is quite short which forces you to practically fill the already small chamber close to the top leaving little room for air. Okay, like the friends said, the ball bearing will alllow excess smoke to escape. I did this : took 2 or 2 thin diameter folding elbow drinking straws and the uncut ends I put squeezed together into the shaft, measure what distance to the bottom of the bowl, and cut the other side of the straws. When placed into the watter they splay out and extend shaft length .Its also a great diffusser which will cut down on noise. Link to comment Share on other sites More sharing options...
coplinb Posted July 28, 2008 Author Share Posted July 28, 2008 thanks for all the input everyone, i was toying with it while i was smoking last night and would keep it shut while smoking, opening it back up every few hits to let out some stale smoke. i was getting a pretty good smoke out of that little thing, i had my doubts but im impressed so far. Now i just need to get some better shisha! Link to comment Share on other sites More sharing options...
