3.7 million views and did anyone pick up on the fact that the whistle/safety valve is defect, then with the arrangement shown how was pressure raised.
With the pressure sustaining parts of this valve missing something is awry, I suspect that it is blocked off somehow otherwise no pressure could be raised.
Therefore; this machine is not fitted with a safety valve, ok if you know what you are doing but I have reservations.
