Thank you for contacting Inyo. When it comes to plumbing and valves, every pool is different. We can't say for sure which pipe leads to what or how the valve should be set. You'll have to test each one and then label them. 

In the picture below, I've identified what those lines and valves could be controlling.

Check out our article titled "What Does My Valve Control?".

The backwash valve that controls the filter is not in the picture you provided. That valve should be connected to the Hayward ProGrid filter.
