How to tell if a pipe is pressurized

I need to tap into a line that is going to a hose bib, so that I can add another hose bib in another location. The problem is that in the place where I'm gonna dig to get to the pipe, there are actually 3 or 4 pipes running together in that trench. Only one is pressurized, that is, going to the existing hose bib. The others are different sprinkler zones. Is there a way to determine which pipe to tap into? Or do I have to just start cutting until I find the right one?
Thanks.

Run the exisiting hose bib and see if you can hear or "feel" which pipe it is. Careful, as it is tricky. One running may sound like the other one and visa-versa. Really no other way to tell.
I'm no expert..........YET! :D I just like to suggest things and learn... :thumbsup: See what the pro's have to say first.
