The only time i have ever experienced a wet draw on a DH was when the reg fell over on a dive boat and, unbeknownst to me, the inhalation horn cut into the hose making a small hard to see rip. Thought I was gonna die but I relied on my high tech alternate bail-out system and that saved my life. My high-tech system? Swim up toward the surface while exhaling. Works most every time. Mark.
I've done it both ways (had an old OMS wing with bungies) and, aside from looking more streamlined when deflated, it's still fills the same space when inflated. I have never experienced any problems using any kind of wing with a VDH backplate and DH reg. Blocking a few exhalation holes shouldn't have any effect. Your setup looks spot-on. Good luck.

Yes, fix that first.CAP2ND1961 wrote:I think I found the culprit. The mouth piece I installed is loose and can be easily moved around in a circle.

Next, check this: When you rotate the DSV you should feel a bit of resistance just before it reaches the full open or full closed position. If not, the o-ring (in the rectangular groove) around the port that serves the mouthpiece could be compromised.
(Thanks to Luis for sorting mine out recently.)

See the pictures below, I would think this would be where the water is leaking in. I rotated the dsv and it is smooth no signs of grit. I either need a new mouth piece or a better fastener.
I can easily rotate the mouth piece around. Im pretty positive that I should not be able to do that.
I'm sure everyone does it differently, but whenever I'm done diving (whether for the day, weekend or week) I take the hoses off the horns, run warm water through them, then hang them up to dry (with the mushroom valves adjacent to the mouthpiece pointed downward so it will drain). I hang them up in a cool dry place because too high humidity and/or lack of air flow has the potential to cause growth of nasty stuff inside (said from personal experience based on neoprene hoses - not sure of the potential on the newer silicone hoses.) Doing that, you should not have any problems. My 2psi. Mark
