Well then the pump maybe my problem because when the pressure rises from 6 to 10-11, my flow drops to nearly nothing..skimmer not skimming, robot not robotting. Also, because it's Intex, I had plumbing issues. So, if pressures need to be higher, I'll need to upgrade a couple rubber couplings to the metal-covered rubber couplings, cuz I dont believe the ones I have will hold as they are already swelling from the pressure at 10psi. It's really sad that Intex feels the need to stick it to us like that with their fittings.
