How is it they heed the advice of people who say they (YS) are nothing but trouble and challenge the advice of those who have good sucsess ? Oh well I guess it is self explanatory !

Yes , a dirty regulator can cause the leakage but the check valve is an easier fix to try and it is the more common problem.

The YS is DIFFERENT than others and only harder for those who have a hard time adapting to DIFFERENT. Once set up they are very unfussy and NOTHING in their size and type runs as well , NOTHING>
