Bottom. I cut slots in it with a Dremel/Cutoff wheel. Works well, but you have to trim out all the little "flakes" still holding on to the CPVC. I drilled my cooler at an angle so the drain comes "up" from the valve to meet the manifold which lays flat on the bottom of the coler. Guess you'd need to see it to get the point. I can take pictures if you'd like.

I put mine on the bottom as well, but I'm not sure you get more or less dead space either way?

If your holes are on the top, once the fluid level gets to them, you lose siphon and you can't lauter any more. This will leave a volume of wort in the bottom equivalent to the footprint of your tun, 1 inch deep. If they are on the bottom, you have positive pressure almost the whole time, and you leave a fraction of the liquid behind.

But won't the wort level only go as low as the outlet out of the cooler? In other words, if your outlet valve is a half inch off the bottom, that's as far down as the level can possibly go. It's been awhile since I studied fluid flow, but it's similar to what makes a sight glass work right?

Yes but if you have tubing attached , the lowest point becomes the end of the tubing, which is well below the bottom of the tun.

Anybody have any suggestions for my cpvc manifold. I've used it 4 times now and it is getting to the point where at the joints want to slip away during the mash. Is there a food safe glue to put these pieces together so that my manifold doesn't fall apart during a mash.

Actually I do have your solution. Instead of using 90's for your corners use t's and extend the piping until it hits the wall of the cooler. Put end caps on extended pipe and it should fit snug(takes some trimming). I also used some cpvc cement at strategic points so that my manifold held together but could still be disassembled for cleaning.
