    Slow hiss after firing

    I have a classic valve with a hurricane regulator. When I pull the trigger there seems to be a light hissing sound when I hold the trigger down which over a 1ish second period goes away.The hiss is coming from the bottom of the valve. I don't know if its the regulator or the on/off. Any clue to what it could be?

    Likely the on/off. When you hold the trigger it should be stopping air from moving past the regulator so either the air that is trying to move into the dump chamber isn't completely sealing off or the air that resets the on/off isn't completely sealed off

      Putting new orings on everything in the on/off it still leaks. I found a small gouge on the surface where the dual orings sit which seal the pin. I'm beginning to believe that gouge is whats causing the leak. Perks of buying used.
