I'm not sure what the bottom chamber is called, but I'm quite interested in some knowledge. Thank you for your time
Inline to 8 stem. The perk on top can be called anything there are so many variations of that perc. Hisi makes a tripple geyser bong and they have a similar perc to the one you have on the top. I believe they call it a bell perc. Inline to 8 arm. That could also be just a splash guard at the top so no water rises too high
yeah i figured the 8 arm perc to be a splash guard of some sort. Thanks for informing me about the inline.
It's kind of hard to see in the picture but it looks like a splash guard to me. It looks like it doesn't have a riser in the middle, and it looks like it has slits at the top.
I would say top one is a splash guard. From what I know pers always retain water, besides maybe swiss and pillars, that one is designed to let water fall down to the tree perc. Best regards K
