I just purchased a home with a pool. While I have the chemistry down (thanks to this site) I'm finding I still have a few questions on the pump and filter I was hoping to get help on. Specifically:

The arrow points to a diverter valve which pumps the water to either filter A or B. Both use the same skimmer (there's only one), but return the water to the pool through a different return line. Why are there two filters and what is the purpose of the diverter valve?

This is right next to the pump and filter. The arrow points to a dial that I'm not sure the purpose of, but since the PVC pipe after it goes into the ground next to the pump I am assuming it's pool related. Any idea here?
Any thoughts would be appreciated. Otherwise, I'm enjoying my pool so far!
