Thanks, I figured it's a slow time for most people with pools. Just starting to figure mine out really. I did figure out last night that the valves on the last picture, if they are both pointed up towards the pump and the top picture valve is pointed to the left away from the other 2, just the spa is on and bubbling. No pool water is going into the spa, just spa going through the loop to make heating quick. Other than that, I'm not 100% sure.
