Malfunctioning Sprinkler Valve
My sprinkler valve is not working. the solenoid and everything works but when i start pumping the gun up the air just flows out the barrel. I have made 6 pneumatic guns before this but this is my first sprinkler valve.

Did you leave the solenoid on?
Always rely on Murphy's Laws 4.If you have enough grease & a big enough hammer, you can put anything... anywhere
3.If all else fails, hit it with a big hammer
2.Matter will be damaged in direct proportion to its value
1.If anything simply cannot go wrong, it will anyway
Is it a normally open valve ? 
As in does it close when you apply current to it?
Also check your solenoid with an ohmeter. Or maybe your wiring is faulty.

Well, if you blow in it and air comes out the other side, how can you say it's closed? 
You can buy an ohmeter or multimeter at an electronics store. It should be cheap and a multimeter is always useful around the house. Alternatively, you could wire the solenoid in series with a battery and a light bulb (must be small enough to work normally with the battery you're using). If the bulb doesn't light up, the circuit is open, therefore your solenoid is damaged.

it looks closed and i cant see anything
thanks
if it helps any, i've been trying to modify the valve with the blowgun idea but i don't have the blowgun. So right now there's a hole drilled in the top with a steel hose coming out.
