I am trying to figure out the piping arrangement for the pool at the new house we just bought. Where do y'all think the Blower ties into the spa return? In the photo attached there appears to be two return lines for the Spa?

so there must be a tee with a crossover underground. Thx for the help.

I think each of the spa return lines runs to different set of jets. I don’t think they are interconnected.

My guess is the valve lets you select one set of jets to get more pressure from the jets or have both pipes flowing for all jets.
