I just stated assembling my all grain stuff got 2 5 gal coolers and I built a cpvc manifold out of 3/3 piping it seems a bit small and I'm a bit suspicious as to its efficiency. It is square with another "leg" bisecting it leading to the outlet. Doesn't seem like enought tubing to me about 17 inches of tube with slits. As it didn't cost me much scrapping it is not a big deal. So now I got another idea to build a false bottom out of a stainless steel pie plate like one I saw built out of a pizza plate here's my rendering of it let me know what you think.

as you can see the pvc that connects it to the spigot will go in the the side of the plate what do you guys think of the design will it work?

I looks good. It reminds me of the phils false bottom that i have. The only concern is the pie tin caving in from the weight. Also, do you have enough holes drilled to let the wort flow?

It's a thick stainless steel job so I don't think caving in will be an issue but now that you mention it maybe I'l add a bolt for support there will be lots o' holes in there.

Looks good to me...just make sure to spread the holes evenly all about it so you won't have channeling to one place. Also consider ease of disassembly in your design for cleaning post-mash.

I made my false bottom out of perforated stainless. My bottling bucket has a drain fitting in the side down low, like Voodoo's pic. But I cut my false bottom into an oval shape, so it fits diagonally from above the drain to the opposite bottom corner. But I use a grain bag too. Never had any grians in my wort, nor any plugged sparges. Make a loop of wire through the high side for removal, or it may become a permanent installation in the bottling bucket.

One thing that I noticed is diffeent from Phil's and others... why is it that the output hole is in the center and comes up and to the side... instead of doing what you are doing and having the output on the bottom?

The reason for the Phil's design having the outlet in the center of the dome is to reduce the amount of foundation water required. With that design, very little foundation water is required as the input to the outlet is very close to the real bottom. With a flat false bottom taking the outlet from underneath, the false bottom would have to be positioned above the outlet from the cooler (about 1 1/2 inches above the real bottom). This would require considerably more foundation water, and reduce the efficiency.

So my design would work but it will be less efficient?

Looks like it to me, and you could easily make up for the loss of efficiency with an extra pound of grain.

Good luck
