Re: [PSUBS-MAILIST]automatic over pressure valve



Real good idea. Some way of "dumping" stuff seems like a great option.
I was always thinking along the lines of a high pressure piston pump like what would be used to change the VBT at depth, but just a bilge pump-to-snorkel would mostly do the same thing for a lot less hassle.
Then again.....
HP air from a scuba tank could dump a little VBT.
Could you put a hard tank ( little one) to receive the bilge water, then valve it off, and then blow it out through the snorkel valve using the HP air.?
I'll make a little note for my file, the hand pump to snorkel is pretty damn simple and sounds very useful.
Thanks for the tip. Frank D.
