What he means is that if you pull, the pump is connected to the effluent side of the reactor. The intake line going into the calcium reactor remains submerged in the sump so that when pump is on, it pulls the water from the sump through the reactor and then into the pump at which point the pump pushes the water from the reactor it back to the sump.
