Thinking in terms of cross connection, though, I think I would shut down the sprinkler system, crack the drain, and see if there is flow. Then I would throttle the domestic, keeping some flow to push water toward the sprinklers. then, with a stethoscope or one of those fancy gadgets I'd try to pinpoint where there is flow. Larger pipe towards smaller, of course.
