Just curious here. I have a mag 9.5 running out of my sump. According to the head calculator on this site, I would be ahead upwards of 200gph if I were running 1.5" pipe vs. the 3/4" pipe that is on it now. The only catch is that the output of the pump is a 3/4" fitting. If I step up the output to a 1.5" will I still achieve this increase in flow?

also, does anyone know what the input thread size is on this pump, I know it is threaded, I just cant figure out the size. It looks like it might be as little as 1/2".
