Phil: Thank you for responding. I plan to go ahead this weekend and put the holes in my lid for the 4 inch fittings, with the center one a few inches off center.
Brian: Thanks again for your detailed photos. I really like your idea of using the two angled fittings on the outside and inside for the input line. That looks like it should reduce turbulence significantly. I also bought one of those PVC to Clay pipe adapters - that also looks like it is going to work out great! That is exactly what I was trying to do, but couldn't find a way to do it until I saw your post.
Looking forward to getting this thing built and tested!
Thanks again everyone.
