4 years ago we built a 20,000 gallon In ground Gunite chlorine cartridge pool with a variable speed jandy pump. Over the weekend we drained it (cya was high) and cleaned the filters. I have spent most of today trying to get it going again. I have attempted to prime the pump no less than 20 times. The water level is over halfway up the skimmers. I’ve got the 2 skimmer lines open and the main drain. I have tried getting it to work with the pressure gauge open and with it closed. We did get it going for about an hour and it seemed great (water never quite filled the pump basket, but was close). We had the bubbler and all the fountains going. Then the pressure/flow went back down without warning. Tried to prime it again without luck. At my wits end. Ideas?
