After chasing a maddening cavitation issue...
Replaced internal parts (impeller, diffuser, wear ring)
blew out lines
checked pressures on both sides of pump
everything based on extremely valuable tips from pool boards...
Maybe its all pumps... but the tristar apparently no longer likes its basket. I noticed one of the reinforcement ribs bent on the impeller side of the basket that keeps the walls on it straight. This was based on a local pool techs phone call to check the basket and or run the pump without it...
started pump up with removed and immediately 25 pounds back from 8 and flow is normal again...
Sometimes the easiest way is right under the lid.... greatly relieved...
