Tunze 9002 Nano Skimmer

[cav~firez22]

I recently bought this skimmer new, and upon installing it in a RSM, i noticed something odd, the venturi does not appear to be working.

When the skimmer is on, all it does is pump water, there is no air being drawn in through the Venturi. I have checked, and it seems evertything is intact, there are no kinks in the hose, and the valve screw for the air is full open.

Has anyone had this issue with these units before? perhaps someone could shed some light on this situation for me.

Thanks much,
