um.. could someone please tell me how the hydro power pressure system in water warriors works? diagrams would be appreciated. thanks in advance.

If you know how CPS works in general, it's fairly simple. The water is compressed by a flat rubber disk. The disk stretches and buldges out, then when you pull the trigger, the valve opens and the rubber disk pushes in, which in turn pushes the water out.

This is a newer method designed to get around CPS patents. It's slightly less effective (but that's also be cause BBT uses small tubing), but still works nonetheless.

For water guns in general (that have seperate compression chambers), the idea is to pump water into a compression chamber. The water goes through a one-way valve (a check valve), then the pump pushes the water into another check valve, then the water is held in a compression chamber between the second check valve and the trigger valve. Following is a diagram of a primitive water gun (as in original super soaker series) with a seperate compression chamber.

Stuff can be moved around a lot through different designs, but they all follow that convention. Other differences include the pressure chamber (in the case of the Hydro Power, it uses the rubber disk I mentioned, not air pressure), as well as the firing valve used.

You can also do search for other explanations or pictures.

It's a very difficult system to pull off right. In a traditional bladder, most of the force vectors cancel each other out; here, there's a massive amount of force acting on the plate.

Still, the BBT water guns seem to cope with the pressure well enough, as evidenced by their fairly thick bladders and decent range. As CA-99 pointed out, though, the thin tubing restricts flow and power on the larger stream settings.
