Free flow mania!

[Flea Dog]

Most regulator manufacturers say their non-cold water regulators are good to 50 degrees F. Below that temp. a regulator can freeze up and free flow.

Theres always the garden hose trick btw, just fold the damn hose over and hold it kinked, never actually tried it, but id imagine it would work until the situation could be sorted out

That assumes a correct diagnosis of a second stage problem. If you're wrong and the 1st stage is free flowing then you'll have anak pressure in an IP hose intended for <200 PSI and a catastrophic blowout is llikely.

We see free flows a lot in 40 degree water in MN. I've never had the experience, but last weekend while diving in fairly cold water one of the divers with us had it happen on two different regs while at depth and in cold water. We usually detune the reg most of the way (makes it so it's a little harder to draw air, but isn't really noticable to you) and then pull back the hose protectors a little bit from the 1st stage. Seems to really help.

I'm betting it froze up. That is a very cold and clear lake. Most rental regs are not really well suited for water that cold.

And the winner in the catergory of "profile photo that just makes me feel weird" is...
