Need help: Which valves control what?

[justinjla]

All of my labels have faded away and I don't know what all of them do. I have a 17k gallon pool with spa, cleaner and waterfall. I have one pump, booster pump, heater, two wall skimmers and DE filter. Here is a pic of my equiptment. Can someone help me understand what everything controls? Thanks in advance!

There is no way for us to tell exactly what each valve does. I can tell you the everything before the pump is suction and after the filter is a return. You will have to turn them on and off one at a time to check where the flow is coming from and going to and then label them.
