Multiport valve pentair tagulus

The valve at the #2 red arrow should have the center white arrow pointing right or left.

The center white arrow is where the internal gate is and it points to what is closed.

Pointing left means that the solar is on.

Pointing right means that the solar is off and bypassed.

What is the thing at red arrow #1?

Is it a check valve?

Is it installed correctly and working correctly?

What is the pressure with the solar on vs. off?
