–Travis from Aztec Solar came out for air bubbles and leak. They’ll have to schedule two guys to come back and fix leak. Air bubble problem seemed to be a consequence of too-low pump speed. He mentioned something about (1) wrong pump model number entered into the solar controller, and (2) some confusion over RPM and GPM (gallons per minute). Key to diagnosis was him demonstrating that vacuum relief valve wasn’t the issue, by uncapping it to show water spurting out–except water didn’t spurt out, showing that pressure was too low. After applying (an unclear) fix, water spurted out.
–Took a swim. Pleasant.
