I think this is how you would run it "normally". I believe this is what pooldoc described, I just wanted to play with photoshop for a minute


Interestingly, my pool has a similar valve setup. It's capable of isolating skimmer, or floor vacuum lines or spa vacuum lines or combining the three how I like. Same thing for the pressure side returns. I also have two main drains, and also two drains in the spa (one on the bottom, and one on the side of the spa, a few inches from the bottom).
