Hear Water - Not sure which valve

I hear water running from one of our sprinkler valves. I've turned off the water supply. Four valves sit next to each other. Is there a way to isolate which valve is the one water is running through? For example, if I turn the main water back on, is there some screw or test I can do on the valve that will turn off the flow ... that way I'll know what group of sprinkler heads / area of my lawn to focus on?

Where ever the leak is, it's under ground. I did a pressure test today, and all seemed to be okay.

Is there water leaking out any of the sprinkler heads? If a valve was letting water get past it there would be.
Are the pipes plastic or metal?
If they're metal the leaking sound could be anywhere along the mainline. I've heard the sound all the way around the house from where the leak really was.
Is there a wet spot anywhere near where you hear the noise? Could be a leak in the PVC and not the valve.
You can use a tube or piece of pipe to listen to the valves much like listening to a cars motor to isolate a sound.

I'll check again, but didn't notice any leaking sprinkler heads. I think most of the pipes are plastic ... at least the few I've dug down to in the past. And, as I typed those last words, I bet I know where it is. Couple years ago I fixed our spicket that was out near a fence that had fallen toward the spicket and broken the pipe below. Maybe it sprung a leak.

Darn ... that was a pain.

Thanks for responding, and jogging my memory.
