Main Problem: Pump is have difficulty priming at low speeds (1750) and at 2200, it would start struggling around 6pm (7 hours into its cycle). When I say struggling, I mean it would suck water than there would be like a pressure build up than a lot of water come out, than not much out, than some, etc etc. However, at 3400 rpm that doesn't seem to be a problem.
Secondary Problem: I spa would drain back to the pump, in trying to reach equilibrium with the lower elevated pool.
Background/Recent work: My spa is at higher elevation than the pool, so is all the diverter ortega valves. I recently changed the in ground 3 way ortega valves that would diverter circulation from/to the pool or the spa. I have re-sealed it well, with plumbers greases. But now the pump definitely has problems at 1750 rpm (whole point of a vs pump).
See my attached pdf of the pool setup.
I been trying my best to seal everything properly.
