When they sell pumps its rated by head (length of vertical pump) now if you also run this through a partially closed valve it increases your head/backpressure to a point your pump cant handle.            This is all based on the fact that you will have a flow control valve on both the in and out lines in your sump

 So it is preferable to slow down the flow after the skimmer? Have I got that right?
