Point being that you should be able to purchase a cap that you can screw on that drain and stop the leak. Water pressure usually runs right at 60 lbs, so it shouldn't cause you any problems by blocking the drain until you need to use it. If you can get a cap that has an o-ring in the end of the cap or at least use some Teflon tape on the threads before you put the cap on so that it doesn't want to leak around the threads.

Yeah, I have a cap for it, but the problem is that I don't WANT the water to get past the drain. That leads outside to the rest of the sprinkler system and has a nice little U in there where water has a tendency of getting trapped, freezing and bursting in the winter (speaking from experience).
So it sounds like it's going to be easier to just replace the whole thing.
