Aqua pack devastator CVF?

Post by mikehansen » Thu Jun 22, 2006 7:50 pm

Where do I cut? I think I know but i donj't want to wreck my soaker.

Welcome to Super Soaker Central. Do not post this thread twice.

Take a picture of the internals of your Aquapack Devastator and I'll highly the area to remove. 90% of the time it follows the same pattern as displayed in the article, but I have not seen the Aquapack's valve setup, so I am unsure if it does.

My saved OpenOffice.org reply from before the other thread was deleted:

Are you sure you're looking for the check valve? Soakers generally have three valves: one pull valve (that the trigger is connected to) that opens and fires when the trigger is pulled, and two check valves that help water move from the reservoir to the pump to the pressure chamber. Most Super Soakers have a tubing complex right below the reservoir and at the base of the pump tube; your check valves should be somewhere there. The pull valve should be between the pressure chamber and the nozzle and very close to the front tip of the gun.

The APD, as we all should know, is a backpack CPS soaker. A hose allows water to feed in from the backpack, and the pressure chamber should be a large part of the gun, with an opening in the front (you don't need to open the pressure chamber). Because of this layout, the first check valve could be anywhere in the tubing from the hose connection to the front of the pressure chamber. The second check valve should be between the pressure chamber and the pull valve.

Naturally, I guess we weren't talking about either of those valves after all. The other thread hadn't stated that you wanted a CVF, and I assumed you meant check valve as in check valve, not check valve as in pressure release valve.

As you can see, the water always goes through the tubing and takes the fork part that leads through the first check valve and into the pump. Generally, the water comes out of the pump, through the second check valve and into the PC; but if there's too much pressure, a pressure relief valve uses that loop of tubing in the pictures that goes over everything else to bypass the first check valve and lets the water reenter the reservoir.

How do I post pictures from my computer? How do I find the pictures URL?

Check out the thread, "Uploading Images." It's under the New Users subforum and it's been stickied.

I'm assuming Ben made those lines indicating where to cut--and it looks fine to me, although the actual check valve might have been marked rather than the pressure relief valve. It's hard to tell with my inexperienced eyes, though, so he's probably right.

Thank goodness Mouse Gestures allows you to easily cut images' sizes in half--that picture is pretty big.

I did not make those lines. I wouldn't post an image that large, and I would announce myself as well. ;)

The image will be turned into a link after I post.

Even still, that doesn't appear to be where to cut. Typically the place where the pipe increases in diameter is where the real check valves are. The smaller spot is where the pressure relief valve is.

Cut on the red lines. I've tried my best to blur out the yellow lines. Please be aware that we are not responsible if it turns out that this suggestion is incorrect. None of us have modified an Aquapack, so we do not know for sure which valve to cut.

what is this mod for?

I'm about to get one for an upcoming water fight....

Yes the CPS 2000 will be there, and hope to be somewhat of a challenge if possible lol

Check valve freezes (CVFs) involve disabling the pressure release valve (the proper name for "check valve"--real check valves are just one-way valves, so use "pressure release valve" when possible). In commercial soakers, these valves allow water to go through when there is a certain amount of force, and it prevents excess pressure from building up and possibly destroying the soaker. If you look at the pictures, you can see that the valve--which points backwards and towards the reservoir--bypasses the check valve that normally stops water flow. In CVFs, we basically cut out the pressure release valve (soakers can take quite a bit more pressure than these valve will allow, but don't push it), but then we have to seal the opening with epoxy. The lack of this valve allows for greater pressure and power.

CVFs are not specific to the Flash Flood--indeed, they are practically universal.
