The must not hav ben responsible for that, the IP reg must have increased, it happened to me but with an overpresure valvel tum just above the kiss valve pressure you wouldnot have increased your flow rate .
I common failure is a failure of the oring which will allow much more oxygen to pass than anticipated.. The original SS valves needed oring replacement about every 6 months of use, the newer moldedunits are much easier on the orings..
