It's a 6" suction line feeding a 3 x 2-1/2 pump (single phase power - largest pump available) and discharges to a 6" underground. Two reducers for each side. Judging that the color doesn't match on the reducers, my guess is that they didn't order them from the warehouse. I may push the issue as the available space is cramped and we can barely get the 10 diameters (they brought the suction line is at the opposite end of the pump room from where I told them)
