Where does the air control valve go?


It makes no difference were the air control valve goes.

However the one way valve and any joins should be at or before the highest point in the air line . And glued in place ( superglue)
Should the air line fall apart at a join you need the line coming out of the water to have a one way valve.

In short the one way valve should be at or just before the top of the aquarium ON the water side of the airline.

To avoid all possibility of a back siphon have the pump above the water level.

Sorry for giving more information than asked for but it’s pretty important you think about what you are doing. Many of the one way valves have a tapered male connection and are Notorious for slowly disconnecting if you don’t glue them.
