Re: [APD] New CO2 system

["Tomoko Schum" <tomokoschum at knology_net>]

It may take a while, even weeks or months, for the spring and plunger to
suddenly give under pressure and unlock themselves.  If you have your needle
valve set to the initial slow flow rate, it may be wide open in actuality.  

I am not saying that this is what happened.  I am simply pointing out a
possibility.  In any event, it is a good idea to make sure that we follow
the proper sequence to get the regulator working correctly.  

I have had CO2 equipment set up for two tanks for over 10 years and never
had any failure or problem except for that one time.  I never experienced
so-called the end of the CO2 tank failure.

Ok, if we are in the "i wonder if" mode
 
yes i can see if you didn't open the unit in the proper sequence you could
get irregularities.
 
but my failure happened after the unit had been running for several WEEKS!  
and running at the middle range of one to two bubbles per second.
 
then it went crazy and the flow was as if the needle valve was never
partially closed.
 
Could it be that as the tank got lower the pressure varience caused the
valve to no longer do its job correctly??????
 
This never happened withing days of a cylinder change but rather several
weeks.
 
any engineers out there with an explanation??????
