I am new at this, and I first placed my problem on "equipment and sanitation" and got no answers. I have a Eurofilter Vacuum Pump to transfer wine from one carboy to another (too old to lift a full carboy). Pump works great, but at the end and finished transferring wine, and I pull the plug...
I am using a eurofilter vacuum pump to transfer my wine from one carboy to another and would like to know how to prevent a backflow when wine has been transferred and turn off the pump. When I turn the pump off, it stirs up all the sediment on the bottom causing it to go into my other carboy.
