New Scubapro G250V's, why does the purge button lock down?

[Sonofasailor]

I just got my Scubapro MK25/G250V yesterday and hooked it up to a tank. Immediately it started free-flowing as soon as I turned the tank valve in the open position. After a few tries of this, I noticed that the purge button was stuck so that it was purging constantly. I then noticed that the purge button was turned sideways at the same time, and attempted to correct it by twisting it gently. It did go back, is this normal for the G250V? If so, what is it's function? It seems to me that this would be a problem underwater....

I found no mention of this in my manual, anyone wanna try to see if this works on your G250V? Try pressing the purge button down like normal, and turn it 1/8 of a turn counter-clockwise, it should lock down in place. As soon as you turn it back clockwise an 1/8 turn, it goes back to normal.

This is normal for for the G250 and the G250V. It is an anti-engraving mechanism. It helps to relieve tension on some of the internal parts.

so should it be stored with the purge button down?

Yep, it takes the pressure off the seat and you should also back the inhalation resistance knob all the way out

For storage it is recommended to use the anti-engraving system and to completely unscrew the adjustment knob. It is on page 24 of the manual. FWIW, I'm not the most meticulous with my gear and I never use the antiengraving thing and I haven't had any issues that I would consider
related. Congrats on buying great gear! Oh and don't store that thing - you live in Florida -
use the hell out of it.

Happy Holidays,

What is old is now new.

My BA109 reg did the same thing with a little removeable plastic thingy or you could buy a depresser to do it.

Just make sure the button is not depessed when you give the reg it's overnight soak in freshwater

 

[Sonofasailor]

How do you turn the purge button? I also have a G250V, I read about this in my manual, and I have tried with no luck to turn the button.

I have tried to push it inside, then rotate my finger over it in both directions- nothing happened. It just doesn't want to rotate. Then I have tried to use a more gentle push and rotate, with no luck again. Then I have event tried to rotate the purge button from the normal state. Again, no luck.

So.. how do you really turn it?
