I don't understand your problem. I use my Kangzhu pump that way: I put one of the cups on my left breast, I connect the pump to the cup, then I pump until there is enough vacuum which takes 2-3 seconds, I seal the vacuum with the green airlock and then I make the same procedure on my right breast. That's it. After 10-15 minutes I release the vacuum, massage my breasts and then I pump again. Why are you constantly pumping??
