I just moved into a new house and didnt really get much instruction on operating the pool equipment. It appears that I need to turn a valve to divert the water from the pool loop to the inground spa loop. But try as I might, I can't get the valve(s) to turn. They are Pentair valves similar to the picture. What am I doing wrong?[attachment=0:2pexs7va]p_pentair_valve_d.gif[/attachment:2pexs7va]
