Sometimes, a vibration pump will develop an airpocket in shipping or from storage. To remove the airpocket, use a turkey baste willed with water and push the water through the pump while powered on/operating. Make sure the other end is clear and drained, or connected within machine AND air can escape the other side (through open grouphead valve, steam valve open, etc). This pump can also be found and replaces pumps for most mobile smoke fog machines used in the entertainment industry.
