NetDoc:Was it a J or H valve? We used to run our J valves dry all of the time. Heck, the dive was ended when you ran out of air!!! We always seemed to get water in our tanks.
Really? I never got any water in a tank through a J valve even when breathing the tank dry. To accomplish that you would have to depress the purge on the scond stage with the empty tank/reg combination and then descend substantially to force the water in through the open system.
I did however on occassion get water in tanks through compressors with less than wonderful filtering and separating systems. Compressors on average are a lot better today.
