I have never actually done it, but have thought about it a lot when I was diving the MK-15...
I believe you should be able to do the same on the MK-15 if the water is accumulated in the CL. Then the OPV could be pressurized to act as a dump valve as long as the diver stays horizontal.
Like I said, I have never done it so could be wrong...
not the same as the opv on mk15 as you know is on the inhale side. the exhale side (before scrubber and exhale hose) on mk15 cant be flushed clear of much more than the absobtion ability of the foam so its not so recoverable (one of the downsides of the design)
