Recently moved into a home with a preexisting pool, no history or paperwork left with the home so just trying to wrap my head around our setup. Everything is in the current position from the previous owners with the exception of the valve on the far right which was the aerator. I did turn that off as it was driving the PH higher then it should be.
I am currently wondering what position the jandy valve is in and what it controls? I did read up on the jandy valves and know their theory of operation. currently it looks like its in between two settings. Our pool is setup with two main drains, one skimmer, 3 return jets, and a vacuum port.
Also is there a recommended procedure for back flushing? IE shutting the jandy valve off etc?
pictures should help alot! I do apologize ahead of time if this is a very basic question, Im a pool newbie!
