freeflow

Hey! So I just have a quick question about regulators. I’m a pretty new diver and have only done about 8 dives. 4 with my gear. I have a Prana Genesis reg and octo and after my dive the other day, after cleaning my gear, I assembled my gear again just for fun/practice. When I pressed the purge...

To preface, I am a relatively new rebreather diver (only ~20 hours on the unit). On three distinct dives, with all three being more strenuous or task-intensive, I’ve had an issue where my nose will begin to “free flow” or “vent” on inhalation. My first reaction was to reduce loop volume...

Neither had ever done so before. We entered the water off a beach with a 2 foot swell breaking on the beach. Hauled the gear through the water past the breakers and both our primary regs started freeflowing. The secondaries were ok. Pressing purge putton on the wife's reg a few times stoped...
