Re: [PSUBS-MAILIST] Pre-dive Vacuum



Jim on my sub I installed a small air
pump I made from these small 12v
auto tire inflator. It works very well.

Phil,
 
That's certainly worth putting on a pre-dive checklist.  It will definitely go on mine.  How do you go about it?
 
Thanks,

We never dive any of our subs unless they've held vacuum for several minutes immediately prior to launch - this procedure tests and 'sets' the o rings and avoids a nasty surprise at the end of a large air-gap launch!
