Third, I'm 100% positive that you don't have personal knowledge of all the "incidents" mentioned, and so cannot speak authoritatively on what did or did not cause them.

Fourth, rationalizing unsafe or disallowed practices with shoddy handwavium arguments and invented "facts" is not useful. So please stop.

1). Yes, it does require that my relief valve is connected and calibrated. But I've already done that so that I can pass inspection.

2). Please show me an FRC compressor filling faster than the relief valve can bleed.

3). The two incidents mentioned in this thread were at normal operating pressure. Please find me the one that isn't.

4). Please show me the rule that prevents me from running the compressor for an extra couple of seconds after the pressure switch tells the compressor to stop. Also, can you show me my "fact" I invented?
