It's real hard to figure out your plumbing layout form the picture provided.

This is what I think id going on (usually the Pool or Spa mode would be controlled by automation) so I marked the drawing accordingly. Can you confirm this is correct?

Hard to tell from that picture which check valve is on the spa return line, I can only see 3 of the 5 check valves. I'm leaning to the top left check valve as the spa return check valve. Do you know which check valve is on the spa return line? That would be the check valve I would replace the internals on.

I opened No.2 and checked the flapper the - black part in the image is worn out - time to replace ?

also, i upgraded to a Variable Speed pump - at 1700 RPM no water leak through No.2 but at 3000RPM a-lot of water in No.2

i also have alot of bubbles in return and one big bubble in my pump ... cant seem to figure out the air leak

btw - thanks for marking up my ugly picture - you rock dude - much respect to you !

The pipes within the yellow circle should be your all of you returns.

Blue & red should be your intake.

Orange? Well it almost looks like an automated way to use the heater for the spa only maybe.

What kind of valve or whatever is on the suction side in front of the pump?

Maybe a front picture of all of this would also help.
