    Pumps Calculating head

    When it says 6' head 950 gph ? Does this mean all plumping from pump to pump to the tank or just the drop from tank to pump ?

    It means 6' of head, but head can be created by height, fittings, pipe diameter, or even horizontal runs. Anything that causes restriction to the flow that the pump must overcome is "head".

    If you will have alot of head then you should use a pressure rated pump. A normal pump say a mag style is meant to move water but not with any pressure so any head and the output will run out quickly. A pressure rated pump is designed to overcome the pressure and will pump larger volumes to much higher heads.
