The reason mine are a differnt heights is the main pump, 1500gph with standard float switch, is just off the bottom of the hull and the float swith is mounted on an angled block to keep it parallel to the water line, plus both are as low in the hull as possible. The second pump is an 1100 gph automatic pump which is again mounted on an angled block to keep the pump parallel to the water. Due to room issues it's about 1" to 1.5" higher. So bottom line....if both pumps are pumping out water for an extended time I'm in deep poop.
