Update: bBad news first - while I attempted to open my Water Warriors Jet, I was unable to fully open the blaster. After removing the four screws (one for the battery compartment and three for the casing), I managed to pry the casing apart where I could, but the nozzle cap remained firmly attached, apparently glue in place. I used a couple of thin flat-head screw drivers to attempt to pry off the nozzle cap, but made no real progress, only managing to stress the plastic cap in parts. As such, there is really no apparent easy way to open the Water Warriors Jet.
The Good News - I was able to peek into the internals with the casing partially pryed apart. To my surprise (though I shouldn't have been after seeing the
Water Warriors Tarantula Internals), the trigger not only activates the motor, but also opens a nozzle valve. Thus, I tried the following experiment. With no batteries in the blaster, I pressed my lips to the reservoir opening and tried blowing air through the blaster. If the trigger is not pulled, the reservoir just gets pressurized when I attempt to blow air in. However, if pulling the trigger, I can manage to blow air through the internals and out through the nozzle. That said, if your Jet is not firing, trying to blow through it when there's no water in the reservoir and the trigger is pulled, you can determine whether something is clogged or not. If air (or water if you have some water in the reservoir) can be pushed through the nozzle by blowing into the reservoir, try shooting with it again. If it still fails to shoot, there is something wrong with the pump.
Hope that helps!
