Re: got a little problem
It could also be your ball bearing if you have a hookah with a ball bearing, sometimes they leave the hole opened/ or closed/ and it makes the hookah either get to much air or not enough air and become hard to pull.
Also make sure you are not packing your bowl to tight and are leaving enough holes in the foil , air flow is needed or it will be hard to draw as well.
Um.... Make sure your stem is clean and free of blockages, and also make sure your hose is free of blockages.
I hope this helps you!
