Julia has come to the conclusion that water temperature is more important in pulling a strong vac than the volume pumped/minute..
SWIM's faucet doesn't pump that much water in that much time.. But as long as the temp is cold, her vac is OK..
Rather than going for the biggest, strongest water pump out there to create a vac, just make sure your water bath is well stocked with ice.. Julia say's that will get you a stronger vac.
