Dive Rite wing gaining air?

[Jarrett]

I got to try my new Dive Rite Transpac with Travel wing for an hour in the pool today. I noticed what seemed to be a inverse leak? I would dump all the air from the wing through the inflator tube, then go upside down and make sure there was none that could be released from the bottom dump valve.

AFter several minutes of swimming I noticed that I was gaining bouyancy and checked the dump valve again and air came out. I wrote it off to trapped air and swam around for several more minutes when again I noticed a gain in bouyancy. Again I pulled the dump valve and it dumped air from the BC.

Is it possible for air to leak into the wing? I haven't heard of that before. Thanks.

The inflator can have a slow leak.

It happens. I'd replace it.

yes the inflator is slowly bleeding into the wing, but it is so slow that you don't notice it? I had an inflator stick recently on an open water dive and I was kinda disappointed about how many times I had to dump air before I finally realized what was happening. Every previous time, the leaking inflator was fast enough for me to easily hear it.

I think it is the inflator. Have it checked and replace if necessary.

Yes you have heard of this before. Remember back on OW class when they taught you how to remove the medium pressure hose from the power inflator valve? They typically have you d it in the pool a few times. The reason you learn this is in case the valve leaks air, (or worse, sticks wide open) you can simply remove the air supply.

Thanks for the input. This is a brand new out of the box wing. Would that imply its defective or have something to do with the newness of the inflator?

I also have one of those Hammerhead quacker things inline. It's worked fine for a year on my Zeagle. Although I noticed my Zeagle has a 250psi low pressure inflator hose and my Dive Rite has a 400psi hose. Could this be the cause?

The hose itself has nothing to do with your problem. The difference between the two hoses is the pressure at which they're rated before they blow out.

As mentioned above, hop back in the pool, dump your B/C, detach your LP hose to your inflator and swim around some more. If it doesn't inflate you know where your problem lies.

There are 2, and only 2, ways by which the volume of air inside your B/C at a constant depth and temperature can increase, 1: you're inflating the B/C orally, 2: air is being put into the B/C by your inflator valve.

It's not unusual for the power inflators to develop problems over years of use (unless you service them), but yes, if it happens right out of the box then it's defective and you could ask them to replace the power inflator. Alternatively, you could buy a new one and replace it yourself if you want to get it done quicker.

Jarrett - I had the EXACT same problem with my DR Travel Wing, also fairly new (about 20 dives on it). We initially thought maybe the inflator button was stuck with a grain of sand or dirt. You can free it sometimes by spinning it around. Then I took it to a tech, who found the problem. Inside there are two tiny O-rings. Both were cut. He replaced them and I was ready to go diving. Have someone check your O-rings before you go spending money.
