2 lines found next to each other?

I recently moved into a new house. Got the sprinkler system up and running and found one zone forming a puddle. Figuring the head was taken completely off by a mower I dug out the hole. In the hole I found (2) 1" lines. One is clearly supply with water coming out when I open that zone. The other has nothing. I tried using a hose to feed the other line to see if it runs anywhere but no luck. Anyone know why there would be a second line next to the first? Based on the zone head layout it still seems like a head is missing in that area.

Could be a line for another zone, no?

It is not uncommon to have multiple lines in the same trench hard against each other. It's not the best practice but it happens.
I have the same question: another zone?
Perhaps one that has been abandoned?

Maybe that's your mainline and it's not under pressure until the master valve comes on. Did you have to cut it open to test it?
