Dump Valve Setting

blackvet · 30th July 2005, 19:04

I'm new to the Dolphin and I have to say I'm loving it! Feels a lot nicer than twin 112's! I'm curious to know how you more experienced Dolphin divers set your dump valve while diving. Any suggestions... Thanks Mike

I normally wind the valve all the way in for tnhe Positive pressure check and then 6 notches out. Start at an arbitrary setting (like 6 notches out from full on) and play with it till you loose the 'puffy cheek' effect and/or it vents at a maximum interval.

Once you have the setting you like just remember how many settings from full on it is.

My OPV has 4 clicks to it. I leave mine at the tightest setting, but I do like I'm not suppose to (according to the official TDI course) and put EANx40 into the EANx50 orfice mainly because I just can't breath that fast. I'm getting a couple of bubbles every 8 - 12 breaths. Keep the loop flowing, Dave

Welcome Blackvet to the Dolphiners.
When diving it SCR I tried to find the setting that made the chipmunk cheeks bearable, but in the end I would just exhale a portion through the mask (to clear it a bit) before the chipmunks developed. Worked great.

As CCR I have it wound fully down and that is where it stays until servicing.

Hope that helps.

Same as Wiz
Prefer it wound all the way down and just vented through my nose when I felt my checks starting to puff.

Wiz what happened to my Dolphin, does Jonathon still have it ?
Is it a CCR yet or a dust collector ?

Cheers
Chris

Hey ho Chris, it has some dust on it, but is ear marked "for sale" or as an O2 Deco unit. Which ever comes first.

That is unless I borrow the scrubber to have two. ;-)
