Now that I've stopped using the manufactures' angled siphoning/racking tube the device works great.
I attached a food grade clear hose without any connectors from the side of the Enolmatic arm to a RIGID food grade racking tube on the wine source side. This flexible hose ends about 1/2 inch...
I had a few good years, now I don't seem to be able to generate the necessary vacuum to lift wine against gravity.
Does anyone have any suggestions? I have replaced the O rings without help
