Re: ball barings?
well, my hookah has seen several years of heavy use, I guess I just never thought about cleaning the purge valve, it was kinda stuck when I bought it.
It is practically welded shut lol, only thing I can think of would be maybe PB Blaster but that stuff lubricates and doesnt wash with water, and is VERY TOXIC. Not a good idea to smoke it lol.
It's just one of the things on my list that will eventually get me to buy a new hookah.
