    My Atomic Aquatics B2 1st stage regulator is leaking. It is not a small leak, it is basically freeflowing.

    The air is coming from a vent in the saddle. From this schematic.

    The air is coming out of this vent.

    Any ideas on what it could be? I'm thinking maybe this o-ring.

    Just to be clear. Unless it is something easy I'll be taking it in to get serviced. Just trying to understand the problem a bit better.

    That is the most likely source, if you have the socket it’s an easy fix, even if you find the nut loose you’ll probably want to change the o-ring.

    yes probably that o-ring. You can accidentally loosen up that fitting if/when you partially purge the first stage and then begin to crank on the yoke screw and then also rotate the regulator body relative to the tank valve o-ring face.

    I often see people do this when a reg is "stuck". They get frustrated and start twisting things, Rotating the first stage (when there is tension on the yoke screw) can tear up the tank valve o-ring AND loosen up the yoke screw nut.

    Ok thank you. I may just need to get this one serviced.
