The complaint sample was evaluated and was confirmed to be leaking around the diaphragm area and bottom housing.Three additional samples, similar to the complaint sample, were pulled from existing inventory and these samples were leak tested for 24 hours.No leak was observed on any of the additional samples.A dhr review was conducted and there were no manufacturing anomalies associated with the reported complaint condition.The definite root cause of the reported complaint condition is unknown.A potential root cause might be a shift in the diaphragm, which may have created the potential for bond strength degradation and material separation between the diaphragm and the bottom housing components where the leak was observed.Quest will continue to monitor complaint trend.
