Well recently my pool pump started losing pressure, I just did a lil backwash today as we had that HUGE 'haboob' here in phoenix, plus my pressure was high @20. Anyways, The pressure seems to be fine when I just run the skimmer, but when I switch it over to the vac it slowly moves down to zero. Ive noticed it over the past few days but have not put two and two together. The jets hardly push out water the aerator is almost trickling. I can fiddle with the pump building pressure back up with the skimmer then switch it over to the hose, but eventually it just repeats this process over and over again.
I have a Sand Filter, and a Barracuda Q7.
