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 see...
