Compare your watering schedules and operating durations. (4) Check your controller. You may not have made changes, but have you looked to see that it hasn't failed in some way causing it to operate differently than you expect? Perhaps a lightning strike messed up its programming. You could set the start time to run in the morning so you can monitor if it is operating correctly.

You might also want to check your rain sensor. If it no longer stops the system from watering, it can cost you. If you have a multimeter, or know someone who has one, the standard Hunter and Orbit controllers will show a short across the rain sensor connection terminals when the system is not preventing the system from watering. If it shows an open, the system has stepped in to prevent watering. For your concern, need to check after a good rain to see if it has stepped in to prevent watering.
