Ots Guardian diaphragm issue

[Craig Myers]

Has anybody had an issue with the small diaphragm that allows dry air to flow on the lens area to consistently free flow? It's not a large amount of flow but enough if there were coms installed you wouldn't be able to hear me talk.

if that knob on the side of your lens is free flowing then it is either defective or you do not have it closed. it is an ambient valve so that when bobbing on the surface say waiting for others or your buddy, you can save your tank gas and breath ambient air until you go down. you are supposed to close this knob/valve just before you submerge.

It's not the ABV. If you look at the reg. There is a separate port for air to flow like a defrost on a car up the lense. That diaphragm is leaking.

is your reg slightly free flowing? i wonder if the reg needs an adjustment or maybe the IP is too high for the reg? or maybe a small pc of debris stuck under the flapper?

Not sure. Wish I could tear into it, but I'm heading to a service tech now. I want to take the service class so I can work on it myself. I'll update what we find

Going ahead and getting it fully rebuilt. Found a deformed diaphragm seal that was causing the leak.
