Rapid Exhaust on Inflator - pros/cons

[Locus]

I notice DSS specifically notes on their site that the Torus wing doesn't have a rapid exhaust on the inflator hose. I currently dive a jacket bcd and am shopping for a bp/w. My jacket has a rapid exhaust and I like to use it for descents. Is there a specific reason DSS would leave this feature out?

Also, is it significant that the inflator hose on the torus connects to the center of the wing and not at the shoulder?

I love my DSS gear, but the center location of the hose is an "inconvenience" with my first stage for diving singles.

As to a rapid exhaust (aka - pull to dump), if you are so inclined, swap out the elbow/assembly. DR/DGE makes the part, but the only tricky part may be to find an appropriate thickness washer....

I'm having trouble finding the part on the DGE page. Would you happen to have a link?

How much of an inconvenience is the hose placement? I will be diving singles for the forseeable future.

The reasons wings shy away from pull-dumps on the inflator hose are:

1. They add mechanical complexity and a failure point. Overly-vigorous tugging on the inflator hose has caused the hose to pull off or the fitting to fail, resulting in a failed BC.

2. They are not needed!! Raise the inflator hose, press the dump button, and viola!! The air is released and you sink. Once underwater and in proper horizontal "trim", you will most likely use the lower dump valve anyway. This takes a little practice, but becomes natural after awhile.

Best wishes.

If you want a 'pull-dump' ( and I agree w/Leadturn ) you can avoid the corrugated hose from pulling off the elbow/inflator by putting a line inside it and attaching one end to the inflator, the other to the elbow.........some manufactures do this w/BCD inflators.......

Pulling on a corrugated hose is a really bad idea even if they did think a pull dump was a good idea.

When I was new, I pulled on mine and tore the hose right in half at one of the convenient perforations, leaving me with no way to inflate the BC.

Pull dumps are cool, but I like them separate, like on a butt dump, not as part of an elbow connected to an inflator.

I have wings both with and without a pull dump on the LP hose. I think I use the pull feature about once every 5 dives. On descent, holding the hose up is no big deal as you are going to need it to add air once you get some depth so your hand should already be there. Adjusting while diving horizontal is easier with a butt dump. My take is I prefer skipping it, more parts to break. I would spend more time figuring out if the hose is the right length, many are too long. I am not to the point of replacing my pull dump but I certainly would not miss it.

Once you have located the part, wait for a while before you order it. You may well find that you will get used to and like the simple elbow.

Those style hoses also like to break just from being bent as well. The Goodrich style corrugates hose are just an all around better choice.

(Though I am a pull dump fan, and put them on all my BCDs/Wings.)
