I did have a stuck sparge on a hefeweizen towards the last two or three gallons but I think that was because I didn’t mix the rice hulls in well enough. I did see someone place a manifold like this in a large mash/mesh bag (paint strainer bag) and think I might try that as well. Also, 6 ounces is awesome, maybe I’ll solder my connections after all…

I would avoid sweating if at all possible. Having done a soldered manifold I replaced it with another one unsoldered as flushing all the grain husks out of the soldered version was a PITA.

IMHO, disassembly for cleaning purposes is a must.

I soldered the ends with all the T's/elbows together and the "H" in the middle together. Essentially, all the vertical pieces are easily separated for cleaning. Cleanup was super simple and I had no concerns about spent grain after use. I'll try to post a final (soldered) pic tonight or this weekend and explain further, just in case my description is not clear.

I'm not surprised a hefe might give this manifold challenges. I used a .031 crush on my maiden voyage and like I mentioned in my previous post, it started to really go slow at the 5 gallon point (total was 6.5 gallon draw). I was thinking about doing a hefe here soon and was debating .5 or 1 pound of hulls, probably inclined to go with more due to my initial experience. Good to know, thanks.

This design looks great. I have a similar manifold and the thing almost never sticks! It works great, and after vorlaufing I peg it wide open. The exception would be wheat-heavy grain bills but for instance I just did a dunkelweizen that was about 50% wheat. All I did was throw in maybe .5 lb rice hulls, and it worked like a charm.

I have also wrapped the manifold in a grain bag, that works as well. It was a bit of a mess and it partially came off with the stirring, but then again mine is not as tight a fit as this design here. If you are looking for a bullet-proof solution I might go that direction, but use a zip tie or stainless wire to seal it onto the manifold.

[Edit] Revco I do not crush as fine as .031 BTW, that could be part of the issue. I do get 75-80% efficiencies. How did you do with that fine of a crush?

I did this too! Easy. Thanks! I did not sweat the fittings, so I could clean if necessary and had like 1 cup of liquid left when draining. Cheers!

Looks very good!

You don't need to sweat them because any small gaps work just like your cut gaps...

Not soldering makes taking it apart for cleaning easy. But, putting it back together after a few beers… not so easy

Sorry for the delay. Here's how I soldered my unit. Makes for a pretty easy assemble and disassemble, pretty well drunk proof. All you gotta do is make sure all the slits are facing the right direction. I found I was mixing up a couple of the pieces pre-solder, so I'd have to take it apart and reassemble it correctly. The unit cleans out very well, no complaints.

I used it again yesterday. Fantastic performance...easily got me into the high 80's efficiency-wise with a good crush. Still gotta do a hefe with it to see how she does...possibly next month.

P.S. Don't judge me because of my sweat job. I suck at it, I know...and it was my first go with sweating pipe, ever. I might rebuild it someday, since I now have a better propane tip and 5' of spare copper pipe.
