[PSUBS-MAILIST] Purge Valve

[Alan via Personal_Submersibles]

Thanks everyone,
It might be easiest & safest in my case ( 1 person sub ) to just shut off the
Bottles & reach inside the hull & bleed air & O2 from there.
It saves putting another fitting in line that may leak. Also there may be the
Possibility of leaving the purge valve open, although no doubt you would hear
It when you turned the air on!

Go to "thescubadiversstore.com" and then type in the search bar 46335 and it will pull up a bleed part but the one I have does not the have threaded port for a gauge. The guy was really great to work with and good prices as well. This will get you started and when I get to me shop, I'l look up the part number that doesn't have the gauge port and get that to ya.
