I got Jobo Cascade in my hands, but I don't know how can I attach it to the water tap. I was reading an old post here, but unfortunately I still have no clue.
What I was expecting is the mouth to be "stretchy" so I can attach it to the water faucet/tap, and the water runs without me holding it.
Yes, the adapter is not included. Mine came in a pile of Jobo stuff and thankfully there was a bag of miscellaneous hardware including the right adapter. They're not hard to find (I believe they're used in home-brewing of beer) but it's always nicer when it's just there already.
I'll post dimensions and a photo tonight when I'm back.
