Ok, here's my problem. I just opened up my pool and was using my G3, it will only work for a few minutes, then the pressure in my filter ( Hayward sand filter)
rises to 26 from 18 and my my pump stops suctioning. I turn off the pump then turn it back on and the same thing happens. It sucks fine for the few minutes then stops again, there is nothing in the hose or at the end of the G3 that might clog the system . My pump works great when I don't have it attached. I am hoping one of the guru's here on the forum can give me some advice.
