What does this valve do?
Hi all—seeking the collective wisdom of r/pools. Recently moved into a house with an in ground spa. Still learning the ropes and I think I have a good handle on how all of the equipment works but I am unsure what the 3/4” valve circled in red is for. Any ideas what the mystery valve controls? Should I have it open or closed?
