Our pool's recirc setup puzzles me, here's an overall pix.

Here a close up of the return manifold

I can't find a satisfactory setting on the valves to balance the the functioning of the 3 returns.
In the overall picture the manifold closest is the returns - side/skimmer, bottom/main, then krawler, then there the salt generator and finally the waterfall.
For one the handles appear to be attached wrong. This "!" (handle parallel to pipe) appears to be full-off and not full-on. Shouldn't it be "-" (handle 90* to pipe) to be full off?
I'm basing that on the position of the waterfall return - we keep it normally off - in the "!" (handle parallel to pipe) position, and the Salt Generator which we keep in the "!" (handle parallel to pipe) position.
I _think_ properly set I should have the Side Drain/Skimmer @ 100% open, the Krawler @ 100% open and the bottom drain (there are 2 at the deep end) just cracked. Does that sound right?
Wifie likes to see the Krawler moving busily but it slides down to one of the bottom drains and stays there.
Advice please!
