V,
That is a pressure side cleaner, not a robot, but that has nothing to do with your problems..
Forgetting about your waterfall wall and just looking at your spa overflow... It appears to me that your IntelliFlo pump has to send water to your pool returns, as well as some yet unidentified place, plus the spa overflow... That is a lot of water, so the first question is.. What speed is your pump running when in the pool mode..
Show me the following ScreenLogic screenshot..
Or at least tell me what speed the IntelliFlo runs in the pool mode..
We also need better pics of the valves that are associated with the water feature pump.. I assume it sends water to your waterfall wall. If not, what does it send water to?? We need to be able to see what position the handles are in.. Step back a couple of feet.
Thanks,
Jim R.
