Friction Head

Of course, the plumbing you use will also affect the flow. Long plumbing runs, lots of fittings and small diameter piping drastically increase friction, and this ‘Friction Head’ will reduce the flow exactly the same way increasing the Head Height will. In fact, Friction Head can cut your potential maximum volume of flow pretty drastically. The shorter the run and the larger the diameter of the plumbing, the less friction there will be to impede flow and the more water will arrive at the end of the pipe.
