Default Manifold help..Which is better?

I struggeled with my manifold the last batch (the U shaped one, top picure) do ya think the "O" style one i made will be better? Its for my 5 gallon mash tun, the one i made for my 10 is great cause its bigger of course but the 5 gallon is limited on space. I do 3 gallon batches in the winter so i like the 5 gallon cooler. Just let me know what ya think. And of course using the cpvc i am very limited on bends in the pipe, hence why the new design is very offset.

Thanks in advance, just let me know what ya think will work better, the "U" or the "O" style one. Also with the U style one, theres no support in the middle so i lifted the right side up while stirring and had a stuck sparge

Was also looking at 5 gallon 9" false bottoms but dont feel like dropping 32 bucks on something that will get stuck too..

New version looks better. My manifold built originally for my 5 gallon mashtun transferred seamlessly to my 10-gallon set up.

Remember, keep those slits on the down side of that manifold.

Cool, thanks for the imput. Im hopeing with this design i wont have to worry about one side lifting up and getting grains caught underneith, That was my biggest problem with the "U" design. It would come out nice for the vourlauf but after that it was very, very slow...

Just curious... Is there a reason you chose to use a more complicated pipe design like this as opposed to a simple stainless steel braided supply line? I am wondering what to do, myself.

Cause im a pipe fitter and like to challenge myself....lol


Plus I heard that the SS braid can get crushed over time, cpvc is also easier to clean and remove after each use..

Makes sense... And why did you choose copper over plastic?

To the OP - second design should be better. You want to minimize the distance the wort has to travel - so by connecting the loop, you cut the travel distance significantly for wort on the right side (i.e., it doesn't have to flow all the way through).

John Palmer has a nice appendix in How to Brew:
How to Brew - By John Palmer - Building the Manifold

People use both copper & CPVC with great results. I chose copper because I think it looks awesome.

EDIT: I've heard mixed results on using a false bottoms in the cooler tuns - the heat expands/contracts the size, such that it makes for a difficult fit. You'd want a domed bottom I think to keep the grains out and to prevent channeling on the side. But the manifold works great (esp. for batch sparging) and is much cheaper.

The other member has copper, i have the cpvc...cost is the main thing, i can build a manifild for about 3 bucks using cpvc as oppose to using copper would be about triple that cost..

Cool... I may go with the cpvc too... Sounds good and inexpensive.

SS braid works awesome if you put a Foof Grade plastic hose inside of it - one that fits well - with a bunch of holes drilled/cut all around - (my buddies resembles the star pattern on the flag, rolled up of course!!)

This holds the shape, no squishing while allowing impressive flow. We actually open his ball valve only halfway when I help him on brewday.
