Thanks guys for your input. From everything I've read from you all, it seems to me my original idea of drilling the bottom near the end of the tank and building an overflow box around the area (7" deep x whatever) big enough to install a durso would be the way to go. (three sided box like what Dale was talking about)
Would putting in one 2" bulkhead be a bad idea? instead of 2 - 1.5". I appreciate the idea of a backup overflow standpipe, but would rather not take up so much room for the plumbing.
Also, I would rather not partition off the whole end of the tank. I would rather make a three sided box approx 7" deep x 10" or 12" wide. If I did one 1.5"durso and had an emergency drain pipe as well what would you estimate to be my minimum size box to build around it?
Steve, what if I put two 1.5" bulheads on the side of the tank and built a small overflow box for the two drains, would that suffice for flow and how would the noise be?
