Manifold Geometry Question

[Gerald42]

Hello folks,

I'm just starting to get back into things, and I'm currently trying to build a simple manifold out of flexible copper for my circular cooler.

I'm inclined out of expedience to just make it into a big spiral shape (ie. crimp one end at the center of the pattern, spiral outward to the drain), but it seems like it would create some flow problems.

In your experience, is there some compelling reason not to do this? I'm only doing partial mash batches for now so I only really want ~80% efficiency or something.

Cheers!

Here is a good read on manifild design and geometry and sparging issues associated with false bottoms and manifolds.

Only 80%, eh? I would say that 80%+ would be really good.

Check out How to Brew - Appendix D - Building a Mash/Lauter Tun for some information on manifold design.

5/15 tubing with some holes drilled in it. Been using it for years. I have been getting about 83%.



I don't know how it works on 5 gallon batches. I do 10 and its full to the top.
