Skimmer = suction line
Pool drain = suction line
Spa drain = suction line
What is the 4th the line you are calling suction? They are all suction lines.
Any way, yes the cam adjustment is what you need to check for all of them. You can toggle the switch on the actuator to confirm they are moving where you want.
Make sure there is not a physical stop on the valve that prevents the actuator from turning.
