I borrowed this pic from rogerbrks. Hope he doesn't mind. I've been trying to understand this plumbing thing for awhile. Ok, the 2 red lines are the pumps? What are the yellow lines? And are the green lines indicating the deck jet lines??? If so, does that mean that each deck jet has its own line??? I thought they would be in a loop.
It looks like there are 2 suction lines coming to the main pump. Is everything to the right (where my green lines are)return lines??
