Regulator breathing wet

[Tommed]

I just tested my Dacor Viper Metal regulator which recently came back from its yearly service. I have used this regulator for the past three years and am happy with its normal performance, however following the service it is now breathing really wet. I has to switch to the octopus which oprated normally. Can anyone hazard a guess as to what might be wrong? How is the water getting in? Thanks for your help.

I think you'll find your answers here. The same thing happened to me. Returned it to the tech that serviced it and it checked out fine. Explanation was that the diaphram may have gotten slightly pinched when reassembled. Used after that with no problems whatsoever.

With the Dacor viper series, it would be unusual for the diaphragm to be improperly seated as it is oblong shaped and sits in a very deep groove.

The diaphragm could however have a hole in it, the exhaust valve could be torn or folded, the case could be cracked or one of the o-rings in the case could be improperly seated or even missing.

The tech should have detected the problem before it ever left the shop. It is also a good idea for the diver to always do a pre dive check of their reg, including attempting to inhale through the reg after it is attached to the tank, but before the tank valve is opened. If you get any air at all through the second stage, it indicates a leak somewhere in the system (usually the second stage) that needs to be corrected before you dive.

Usually it means that one of the diaphragms isn't seating properly. Often times it's the exhaust valve.

what he said.

Take it back and get them to open the second stage in front of you..

Did you check the mouthpiece?

Thanks for all the responses. Yes I did check the mouthpiece. Seems to be in good shape.
