I have 3 returns plus my cleaner return in my pool. After installing a poolskim (great product by the way) my pressure wasnt enough to run my cleaner effectively. I placed reducer in two of the returns and it raised pressure on filter gauge to 15lbs and the cleaner and poolskim are working great. Is this pressure (15lbs) O.K. for 1.5hp single speed hayward? I can regulate the pressure somewhat with a ball valve on the single line going to the poolskim but upping pressure to the cleaner reduces flow to the poolskim to the point it doesnt work well and vice versa for the cleaner.
