The complaint sample was evaluated and leaking was seen at no pressure.The leaking was as a result of the relief band slipping off its original position, thereby exposing the pressure relief holes.No definitive root cause has been established.A potential root cause is the pressure relief band slipping when the customer attached tubing to the valve.As part of the manufacturing process, these devices are 100% tested for relief band opening.The root cause of the reported complaint is unknown and is not confirmed as manufacturing related.
