For whatever reason, it is really hard to see the bubbles in the picture you posted. SWG will introduce bubbles when it is running, this is normal.I’ve bled any air from system but still get these bubbles from returns at anything below 2000 rpms. Has been this way since build 4 years ago. Disappointed because rest of water is crystal clear. Tried posting the video but wouldn't allow me.
Checking tonight.Turn off the SWG. Do the bubbles go away?
