Upon arrival customer turned on the front yard sprinklers for me and noticed customer had large amounts of water coming from under the left side of the walkway. Dug up sprinkler line and turned approximately 1’ under walk way and found that customers threaded 90 had snapped causing the leak. Unthreaded 90s from 3/4 by 1/2” threaded pvc T and threaded in new pvc 90s in order to fix the leak. Turned the sprinklers back on and didn’t see any further leaks.
