Discharge Head: This is the vertical distance that you are able to pump liquid. For example, if your pump is rated for a maximum head of 18 feet, this does not mean that you are restricted to 18 feet of pipe. You can use 300 feet, so long as the final discharge point is not higher than 18 feet above the liquid being pumped.
