I got in touch with the guy as well and found out why my experiment of simply sticking my thumb on the skimmer cup outlet hose didn't change anything within the skimmer.
Some KNUCKLEHEAD drilled four air holes in the lid of this skimmer. They are not supposed to be there. I stuck some fingers over those holes and then plugged the outlet hose and wham - the skimmer stops like immediately. Still not exactly sure how it works, but it definately works. I ordered a waist container from AE Tech and filled the air holes with some silicone.
