it seems that Genesis had a machinist issue with a good many of their H and modular Din valves. The O-ring seats have had too much material removed to get a good seal. My wife and I went through 3 valves before we finally got a good one. The dive shop we bought the tanks and valves from handled all this for us and said that Genesis is aware of the problem but that there might be "hundreds" of these valves out on the market. It is real easy to spot as the tank will begin leaking as you try to fill it. Just wanted to let everyone know to be on the lookout for this. At least Genesis is acknowledging the problem and is replacing the valves as they are found. We finally got a good valve and the tank is waiting for us at the DS filled and ready to go.
