So i just got my hookah in the mail and ive been reading alot about hookahs and how to work them and everything. One thing i didnt come across is how to use the purge valve. I watched sambookas video on how to clear harsh smoke and he purged it, but im sitting here playing with my hookah and i cant figure out how the prge valve works.
its this one
the hose port has a ball bearing and the purge port also has a ball bearing. when i blow through the hose, the bearing plugs the opening not allowing me to blow through it
