Just curious: Why is your hopback configured that way? Which is the input and which is the output? Where are the hops relative to the filter (above/below)?
Yeah I knew more explanation would be necessary, just wanted to get back to a book I was reading (the tender bar). The lid is on top and doesn't actually seal (or need to). It's a vertical setup, the quick connect on the side of the canister plugs directly into the outlet of my kettle. This way the beer flow contacts all the hops as gravity pulls it down through the filter and out the bottom. So the filter sits in the bottom of the canister just like it would in a coffee maker. Yesterday (the only time it's been used), I ran the flow rate so that beer level in the canister stayed just below the lid thus all the hops were completely submerged. If the homebrew hopbacks on the market were sold for $100-ish (still maintaining large profit) I wouldn't have bothered making my hopback or posting the instructions. Funny, in general I'm anti most DIY homebrew equipment as sometimes it creates more problems than the builder thinks it solves. Anyway the thing is simple, I bought all the parts in about two minutes and it did work well. I did machine the pipe thread nuts (from a stainless coupler) that you see in the pictures only because I didn't have stainless nuts
sitting around. Let me know if you have any further questions or thoughts. Cheers, j
