TurningTim said:Nice pump! I run dolphins my self but the smaller ones. With that much flow I think your good at 1.5" and would plumb the manifold with 1" pipe and then exit with 3/4" loc-line. But I have another option to loc-line. Search Oceanmotions they make switching devices but they have something similar to loc-line and it comes in 1" pieces.
With that much pump I think it could handle all 1". Its not about pressure its about flow.......
