I must be really dense as I still don't understand what you said above after reading it several times. I assume you are talking about a valve that is between the skimmer and the INLET to your pump. If you partly close that valve you are decreasing not increasing flow and that is a very bad thing to do to a pump. Am I not understanding what you are saying????
