hey scott, looking good my friend. have you found any leaks yet around the bulkheads, only reason i ask is because when installed mt bulkheads i put silicone around the outside of each, on the threads and then titen'd them except for one that i forgot, the 2'' drain and i had a small leak around the threads. also from the looks of your overflow picture it seems really tite in there. where is the sump room located, is it behind the tank, opposite the overflow?.
