What do you thnk of pull dumps?

[Irishdiver]

I don't have a hose pull dump but I only use the shoulder and kidney dumps on my BCD for trim. I don't use the deflator on the jacket's Autoair because it lets water into the jacket. The pull dumps are non-return valves, the deflator is not. Are all BCDs the same or is this peculiar to the Buddy jackets, I wonder...

I used it as the primary way of dumping air with my Seaquest BC when I was vertical. The SQ instructions indicated that was the recommended method of operation. It worked very easily and was very controlable.

Since switching to a BP with Diverite wing, I tend to use the button rather than the pull dump. The DR pull dump takes much more effort to operate and is difficult to control. I tend to only use it at the surface on the initial descent.

Hey Rich, I also have the Pro-QD (with air-source), and I love it.

I used to use the pull dump all the time, but now only occasionally. Rather, I pull the shoulder/ lower deflators, in fact usually. Especially from a head-down position I like to use the lower one.

Omicron once bubbled...
Kind hard to orally inflate on that one then, huh?

Indeed. I ended up on the bottom thinking. "Hmmm....I probably shouldn't have done that....."

As it was I called my buddy over and he slipped the inflator back into place and it was ok for that dive. Amazing what a tie-wrap will do.... I also had an incident once of the mouthpiece pulling off a reg. That was also due to broken tie wrap. Such little things.....

Good thing it wasn't a wall dive.

My wings don't have pull-dumps, which saved me the trouble of removing them.

that's not really true, I have one but don't use it very often, I use very little if any air in my BC.

My second or third dive ever, mine came of in our buddy check.

Never used it since, and purchased a BP/Wing about 2 months later.

used to use pull dump on my oceanic bc and it was very easy action, just switched to dive rite travel wing and it is quite a tug. the velcro hose keeper also doesnt help it, so may switch to using deflator on end of hose. underwater i use my bum dump but it does mean there is a tendency for water to enter

I never use my pull dumps, its just to convienent to use the hose and I find I can control bouancy better. Dump valves dump to much air too quickly and make it hard to fine tune bouancv. As for entry into the water I always have a full bc, diving steel 125's I start the dive - 20 lbs and require half a bc full of air just for neutral.

Been using them ever since they were integrated into the BC. Primarily it is designed to be used when in a "horizontal" position. If you have to much air it is easier to "roll" your shoulder up slightly and gently pull down on the inflator hose vs pull the hose and inflator over your head to let air out.

For those who have never taken their hose off the inflator and/or regulator there is a steel cable that is attached with a pin to the inflator and runs up thru the rubber hose. This cable is what opens the "dump valve".

Some of the BC's on the market today has a dump valve installed on the back bottom of the BC... this is to allow for dumping air in a head low attitude.
