Additional information: b5.Device analysis: product analysis was unable to confirm the reported events through analysis of the cylinder and wqc.Functional, leak and visual inspection concluded the cylinder performed within specification.No abnormalities nor device malfunction were identified with the wqc.Based on this investigation, the investigation conclusion code of no problem detected was chosen because the reported events could not be confirmed nor substantiated through investigation of the cylinder and wqc.Based on the results of this investigation, no escalation is required.Pump analysis: product analysis concluded a pump malfunction based on the identification of a pump functional test failure.The pump failed the inflation test and did not transfer a sufficient amount of fluid to fully inflate the cylinders.Although an allegation related to a fluid leak with the cylinders was reported, based on the cylinders performing within specification, the pump was concluded as the most probable cause of the reported events.An inflation issue with the pump would result in the cylinders not sufficiently inflating and could present as a fluid leak to the user.Based on this investigation, the investigation conclusion code of cause traced to component failure was chosen because the reported events could be traced to a component failure through product investigation.Based on the results of this investigation, no escalation is required.
