Re: Getting good smoke out of a crappy Chinese hookah?
If it's a smaller hookah, a handful of ice cubes in the bottle will help smooth the smoke out some. Not so much a concern with larger pipes, but with a lot of the chinese mini's and such I've noticed they tend to hit better with nice cold water.
Get some plumber's teflon tape at the hardware store and make sure all the joints seal up tight.
Keep the stem and downstem clean, they often corrode quickly on these chinese rigs, ditto on the hose.
