Searched and found little on this topic. Sage advice would be appreciated.

Moving from a steel braid to a cpvc manifold in my mash tun. No particular reason, just bored and curious about how the two will stack up as far as efficiency.

Should I cut the slots on the bottom or top of the cpvc? My thoughts are as follows. If I cut the slots on top there is more dead space and the potential for the slots to get clogged (more dead space effecting efficiency being more important here). If I cut the slots on the bottom it will effect flow.

Right now I'm thinking about alternating my slots left and right of center on the bottom of the cpvc and have it lay on the bottom of the converted cooler.

Thoughts?

I built one and put the slots on the bottom, no issues with flow and of course no issues with a stuck sparge.

I cut mine on the bottom, half-way through the pipe. Works great, and almost no dead space.

Thanks guys!

Any thoughts on angling the manifold so it lays on the bottom of the tun. I think it can be accomplished with an extra T and 90 degree elbow.

Yeah I used a "T" in the middle with a short nipple and a 45. I roll the "T" up 45 degrees and use the 45 to flatten it back out.

It bends pretty easily if you heat it with a flame. for those times when you don't want to spend $3 in gas to get a 15 cent part. Just don't burn it.
