Skimmer not drawin in air

[Peer.Boerner]

I have an eshopps c-120 skimmer which has been working just fine until today. I turned it off to do some work in the sump. When I turned it back on the pump runs fine and fills the skimmer with water but it won’t draw in air. I disassembled the skimmer, checked the motor, impeller, Venturi and all very clean. Checked the air line and no obstructions. I blew into the line while the pump was running and it started drawing air. But strange there was no resistance that I could feel. Not sure what could be going on with such a simple thing. Ideas??

You might be able test the draw or vacuum of venturi by attaching a short piece of airline to the air inlet and dipping the other end of the tubing into water. You would see water pulled into the airline if the venturi is working.

Thanks. I tried and it seems to be pulling the water. I disassembled and reassembled again, found nothing wrong and seems to be working. Maybe I had something attached loosely?? Don’t know.
