Edge EXP exhaust tee removal

[SurprisedOutlet]

It appears the second stage exhaust tee is removable but I haven't figured out how and I don't want to force it. I'd like to know how to remove it in case I need to clear debris or otherwise access the exhaust valve. Any help would be appreciated!

Ten year old thread unanswered but I'm looking for same info. My Edge reg is breathing wet but I see no perforations on the diaphragm and I believe the mouthpiece is affixed tight enough. Maybe water is ingressing through the exhaust valve? Can't breathe in when not attached to pressure though.
