jjccr negative pressure test

[Venomguy]

On the JJ , you look at the ADV button....
It is that simple... if you need a digital tester for that ...:bigdump:

Finally , someone who actually dives a JJ.

ADV depressed for a few seconds on a negative is all you need.

I agree with Ben on 5-10 mins. Longer isn't proving much. I'm unconvinced by 30 seconds - not sure that shows much either!

Matt.

TBH any significant leek shows up imediatly. I do 30 sec to 60 sec neg tests and if the BOV isnt dropping in that time period i am good to go.

So far so good with this method.

If you cant see movement in 30 seconds the leek will be so small i am sure the condensate and drule will outweigh the sea water ingres

As i say on my inspo id leave it in neg overnight but I have changed my attitude since owning a KISS.


On the JJ id have thaught overnight negs were possable if the springs are replacec with proper hose conectors.
