Hi, Pic attached.
With pump at bottom, my 2 skimmers and vac line come in from left, pool drain on right, into manual 3 way diverter valve.
Automated spa drain valve is next.
Constantly getting air in system, have been tracing.
When Spa drain is activated (no flow from pool), I have no air in system, pump basket is clear.
When I de-activate spa drain, I get streams of smaller air bubbles in system. This occurs no matter what I set the pool valve to - as many bubbles from skimmer/vac side as pool drain side, and it worsens as I move the lever.
Does this 3 way diverter valve for pool need maintenance? My theory is air leaking around o-rings (hopefully) or on both sides of fitting.
Appreciate the input and any other troubleshooting.
