Brigade inflator pull dump question

[Bryanmc]

My pull dump seems awfully hard to pull. I'm not really sure how hard it should be. I took the inflator hose off and looked inside. It looks like at "full pull" it's only moving the valve about 1/8 - 1/4 inch max. I'm afraid I'm going to pull the grommet off the bladder. Is this normal or do I need to send it in?

Thanks

It doesn't need to open as wide as the Grand Canyon.

Also, be sure that you're grasping the inflator when you pull, and not somewhere in the middle of the hose.

I suppose it doesn't need to open all that wide, but 1/8" seems a bit short. I do grab it at the inflator when I dump it.... I've seen some folks say theirs were so sensative they would dump when they grabbed the inflator. Doesn't seem like it's right if it feels like I might rip it off the bladder...

your hose is probably one of those corrugated looking ones but not really. I bet if you look inside you will see that it is a flat hose. these really don't stretch all that much.

if not it might be that the steel cable is to long. how much is the hose stretching?

Is it not dumping gas adequately?

I think that is the question to ask

Another is why are you using the pull dump?

I think the problem is that he has to pull on it quite forcefully for it to dump adequately. Am I right?

I had the same problem until I replaced the "corrugated" hose with
a real corrugated hose.
The problem I had was definitely related to the "corrugated" hose.
See this thread on SB: Zeagle Ranger Pull Dump Question
See my post (#5).
The newer hoses are much stiffer than the old ones.
While more rugged, they simply don't stretch as well/easy as the early ones.
If you don't feel like going through the hassle of replacing it, you
can try pulling on the hose with the hose/inflator away from your body rather
than pulling down on the hose with it close to your body.
This should reduce the necessary amount of force quite a bit as
it reduces the pull distance necessary to open the valve.

To try this, you don't even have to dive the BC. Simply put the BC on
and fully inflate it orally. Then try pulling on the hose. You should notice
that it takes less force to dump air if you pull on the hose outward or
even up rather than pulling down with the inflator near your body.

To be honest, the first time I dove it I don't think it dumped at all. That was before I realized how hard I had to pull it. My knighthawk dumps gas fairly easily. After I learned how much force it took I can get it to dump but I'm not comfortable pulling on any piece of equipment that hard, especially not one held together with a plastic zip tie that will be a real a problem if it comes apart at depth.

As far as dumping adequately, dumping all the gas is a 3 move event... pull the inflator dump while dropping my right shoulder, once that's done flip head down... pull both bottom dumps. I'm amazed by how much gas dumps out the left bottom dump even after I've dumper the left shoulder.

As to "why are you using the inflator dump?" I suppose I could hold the hose up and push the button, but there's a pull dump for a reason.

I'm hoping Scott will have some ideas... If not this one will be for sale which is a shame because I really like it overall.

I was doing the testing with the assembely removed from the bc. It didn't seem to open any more or less. As I said earlier, if I look into the elbow while pulling the inflator, a gap of about 1/8" opens where the valve seats. Doesn't seem like a big enough orofice to dump air efficiently, and it still takes serious effort. Maybe some folks could look at thiers and see how far it opens.
