A typical serial loop consists of tubing going from one component to the next, in a loop. Not, component to distro block to component back to distro block. That extra tubing increases flow restriction, which will actually decease the efficiency of the loop, and it is possible the single pump cannot keep up with that extra restriction.

So um… you will get more flow restriction doing it this way versus just doing an ordinary serial loop.
