VEVOR Goat Milking Machine, 6 L 304 Stainless Steel Bucket, Electric Automatic Pulsation Vacuum Milker, Portable Milker with Food-grade Silicone Cups and Tubes, Adjustable Suction for Cows and Sheep

On the bucket lid, there are typically two ports: one connects to this milk/vacuum line, and the other connects to the electric vacuum pump. Make sure the black rubber gasket under the lid is seated perfectly, or the suction won't be strong enough to pull the milk through the splitter. if this answer does not resolve the current issue, please contact us again for assistance.

The splitter (the Y-junction) should be plugged into the long main vacuum hose that leads directly to the lid of the 6L stainless steel bucket. Ensure the two short hoses from the suction cups are pushed firmly onto the two prongs of the splitter to create an airtight seal. The single remaining end of the splitter connects to the thick silicone tube that draws the milk into the bucket during the pulsation cycle.
