Super Confused!!!!! How to Turn On/Off Valves with Multiple Returns and Skimmers

[malimited]

Still a newbie here, only had pool open for a few weeks last year and now I'm attempting to open it up myself. What I'd like to do is use the vacuum to clear out all the debris using the waste function on the filter. I'm super confused here. Where should each of the 3 valves be located so that I can create more suction on one of the skimmers?

Note: Not sure if it matters, but I have 4 returns. The label that says 'Bench Return' has 3 and the label that says 'Deep Return' has 4.

Thanks

To create more vacuum, you need to adjust the valves on the suction side of your pump, not the returns.

Show us your entire equipment pad and the suction side leading into the pump.
